Sheena can row a boat at 2.30 mi/h in still water. She needs to cross a river that is 1.20 mi wide with a current flowing at 1.90 mi/h. Not having her calculator ready, she guesses that to go straight across, she should head upstream at an angle of 25.0° from the direction straight across the river.How long does it take to cross the river in minutes?How far upstream or downstream from her starting point will she reach the opposite bank? If upstream, enter a positive value and if downstream, enter a negative value in miles. In order to go straight across, what angle upstream should she have headed?
Let the direction across the river be represented by the X axis, and the direction upstream be represented by the Y axis.
The current is flowing at 1.90mi/h downstream. Then, the vertical component of the velocity is -1.90mi/h and the horizontal component is 0.
Since Shena can row at a speed of 2.30mi/h with respect to the water and she heads upstream 25.0º from the direction straight across the river, then, the horizontal component of her velocity is given by:
\(2.30\frac{mi}{h}\times\cos (25.0º)=2.0845\ldots\frac{mi}{h}\)Since the river is 1.20mi wide, divide 1.20mi over the horizontal component of the velocity to find the time that it takes for her to reach the other side:
\(\frac{1.20mi}{2.0845\ldots\frac{mi}{h}}=0.5757\ldots h=34.5\min \)Add the vertical component of the velocity of the boat with respect to the water and the velocity of the stream to find the resultant vertical component of the velocity of Sheena:
\(2.30\frac{mi}{h}\times\sin (25º)-1.90\frac{mi}{h}=-0.927978\ldots\frac{mi}{h}\)Multiply the vertical component of the net velocity by the time 0.5757...h to find the vertical displacement:
\(-0.927978\ldots\frac{mi}{h}\times0.5757\ldots h=-0.5342mi\)In order to go straight across, the vertical component of the velocity of the boat should compensate the velocity of the water.
Then:
\(\begin{gathered} 2.30\frac{mi}{h}\times\sin (\theta)=1.90\frac{mi}{h} \\ \Rightarrow\sin \theta=\frac{1.90}{2.30} \\ \Rightarrow\theta=\sin ^{-1}(\frac{1.90}{2.30})=55.7º \end{gathered}\)Therefore, the answers are:
It takes 34.5 minutes for Sheena to cross the river.
She reaches the opposite bank 0.534 miles downstream.
In order to go straight across, she would have to head 55.7º upstream.

If the launch speed of the rock from the tower in the previous question were doubled, what would happen to the time it takes to hit the ground?
If the launch speed of the rock from the tower is doubled, the time it takes to hit the ground would be halved.
This is because the launch speed and the time it takes to hit the ground are inversely proportional.
To explain this further, let's use the formula for the vertical displacement of a projectile:
y = v0yt - (1/2)gt2
Where y is the vertical displacement, v0y is the initial vertical velocity (or launch speed), t is the time, and g is the acceleration due to gravity.
If we double the launch speed (v0y), the equation becomes:
y = 2v0yt - (1/2)gt2
Since we want to find the time it takes to hit the ground, we can set y to 0 and solve for t:
0 = 2v0yt - (1/2)gt2
(1/2)gt2 = 2v0yt
t = (2v0y)/((1/2)g)
t = (4v0y)/g
As you can see, the time is now half of what it was before the launch speed was doubled. Therefore, if the launch speed of the rock is doubled, the time it takes to hit the ground is halved.

what caliber are the rubber balls in the 40mm rubber ball munition for the marines?
The 40mm rubber ball munition used by the Marines typically contains rubber balls that have a caliber of 40mm. The caliber refers to the internal diameter of the barrel or the diameter of the projectile itself.
In this case, the munition is specifically designed for 40mm launchers or firearms. The 40mm rubber ball munition is commonly used for crowd control and non-lethal force situations.
The rubber balls are designed to be less lethal compared to traditional ammunition, as they are intended to incapacitate or disperse individuals without causing fatal injuries.
These rubber balls are usually made from a durable and dense rubber material that allows them to be fired accurately and effectively.
The 40mm caliber provides a suitable size for the rubber balls to be propelled with sufficient force and accuracy while minimizing the risk of causing severe harm.
It is important to note that specific details regarding munitions can vary based on the manufacturer and specific military specifications.
Therefore, it is always recommended to refer to official military sources or consult with experts for precise and up-to-date information on the caliber of rubber balls used in the 40mm rubber ball munition for the Marines.

what happens to the current in a circuit if a 1.5 volt battery is removed and is placed by a 9 volt battery?
Answer:
The current would increase.
Explanation:
The current would increase. 10. The relationship between resistance and current in a circuit is that the greater the resistance the less the current and the greater the current the less the resistance is.
if a 1.5-volt battery is removed and placed by a 9-volt battery in a circuit, From Ohm's law we can say that the current flow inside the circuit will increase because the voltage increases (resistance remains constant).
What is Ohm's law?Ohm's Law is a fundamental law of physics that describes the relationship between the three basic electrical quantities: voltage, current, and resistance in a circuit.
It states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. Mathematically, Ohm's Law is expressed as:
V = I x R
Where:
V = the voltage or potential difference between two points in the circuit, measured in volts (V).
I = the current flowing through the circuit, measured in amperes (A).
R = the resistance of the conductor, measured in ohms (Ω).
In other words, the voltage (V) across a circuit component is equal to the product of the current (I) flowing through the component and its resistance (R). This law is applicable to both DC (direct current) and AC (alternating current) circuits, as long as the resistance is constant.
Ohm's Law can be used to calculate any one of the three variables if the other two are known. For example, if the voltage and resistance in a circuit are known, the current flowing through the circuit can be calculated using the formula:
I = V / R
Here in the question,
The current in a circuit is determined by the resistance of the circuit and the voltage applied to it, according to Ohm's Law. If a 9-volt battery replaces a 1.5-volt battery, the voltage applied to the circuit will increase, which may cause an increase in the current flowing through the circuit if the resistance remains the same.
However, the increase in voltage may also cause an increase in the heat generated by the circuit, which could potentially damage the components or cause a safety hazard. Therefore, it is important to ensure that the components in the circuit can handle the higher voltage before replacing the battery.
It's also important to note that the current may also depend on the internal resistance of the batteries. A 9-volt battery typically has a lower internal resistance than a 1.5-volt battery, which means it can supply more current to the circuit. So, even if the resistance of the circuit remains the same, the current may still increase due to the higher voltage and lower internal resistance of the 9-volt battery.
Hence, The current flowing through the circuit increased when we removed a 1.5-volt battery and replaced it with a 9-volt battery.

A 37 kg child jumps in the air. At the maximum height of the jump, the GPE is 500J. If the mass of the boy is tripled, how much Potential Energy does the child have at the top of his jump? If the same boy's mass is doubled, but his height is quadupled, how much Potential Energy does the child have at it's maximum and in what position in the jump will he be?
Answer:
*Answers are in their respective order with the questions.
\(1500\:\mathrm{J},\\4500\:\mathrm{J},\\5.52\:\mathrm{m}\)
Explanation:
The [gravitational] potential energy of an object is given by \(PE=mgh\), where \(m\) is the mass of the child, \(g\) is acceleration due to gravity, and \(h\) is the height of the object (relative to the ground).
"If the mass of the boy is tripled, how much potential energy does the child have at the top of his jump?"
Without actually plugging and chugging, notice the formula in which gravitational potential energy is given. Potential energy is directly proportional to mass. Therefore, if the mass of the boy is tripled, his potential energy will also be tripled, yielding an answer of \(500\cdot 3=\boxed{1500\:\mathrm{J}}\)
"If the same boy's mass is doubled, but his height is quadrupled, how much potential energy does the child have at its maximum and in what position in the jump will he be?"
In similar fashion to the first question, we can note that the potential energy of an object is directly proportional to its mass and height. Therefore, if the boy's mass is doubled and his height is quadrupled, his potential energy will be \(2\cdot 4=8\) times as large at maximum height. Thus, he will have \(500\cdot 8 =4,000\:\mathrm{J}\) of potential energy at the maximum height. I'm assuming that "in what position in the jump will he be?" is asking for the height at the maximum height of the jump.
The original height can be solved using:
\(PE=mgh,\\500=37\cdot 9.8\cdot h,\\h=\frac{500}{37\cdot 9.8}=1.37892995036\:\mathrm{m}\)
Quadrupled implies being multiplied by four. Therefore, we have:
\(h'=1.37892995036\cdot 4=5.51571980143\approx \boxed{5.52\:\mathrm{m}}\)
A piece of metal has a mass of 60 g and a volume of 3 cm^3, what is the density of the metal..?
====================================================
Work Shown:
density = mass/volume
d = m/v
d = (60 grams)/(3 cubic cm)
d = (60/3) g per cm^3
d = 20 g per cm^3
d = 20 g/cm^3
This means that each cubic centimeter of material has about 20 grams of mass.
A cubic centimeter is a cube that has all sides each 1 cm.
The density of the piece of metal is equal to 20 g/cm³ when the mass is 60 g and a volume of 3 cm³ of metal.
What is the density?The density of a substance can be measured as the mass per unit volume of that substance. The average density is equal to the total mass of the substance divided by its total volume.
The formula for the density of the substance is represented as follows:
The density of material = Mass/Volume
The density of a material is an intrinsic property as it does not depend on its size and the S.I. unit of the density is Kg/m³. If the size of the substance increases, the mass increases as well but the density of the material remains the same.
Given, the mass of the metal, M = 60 g
The volume of the metal, V = 3cm³
The density of metal = M/V = 60 /3 = 20 g/cm³
Therefore, the density of a piece of metal is 20g/cm³.

If all matter has a gravitational force, why don’t two tennis balls on the ground move towards each other on their own?
A. The force of gravity from the tennis balls is too small.
B.The tennis balls are outside of each other’s gravity field.
C.The tennis balls are too small to produce any gravity.
D.There is too much friction between the balls and the ground
(the picture is just of the question)
Answer:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

Using the gravitational force of F= G(m1*m2/r^2)
m1= 5.97 x 10^24 kg (Earth)
m2= 1.99 x 10^30 kg (Sun)
r= 1.48 x 10^11 m
G is a known value, it is 6.672 x 10^-11
All units are proper. Therefore plug in the values and you get 3.16 x 10^22 N.

Answer:
\(\boxed {\boxed {\sf F_g \approx 3.62 *10^{22} \ N}}\)
Explanation:
We are asked to find the gravitational force between Earth and the Sun. Use the following formula:
\(F_g= \frac{Gm_1m_2}{r^2}\)
G is the universal gravitational constant. One mass (m₁) is the Earth and the other (m₂) is the Sun. r is the distance between the planets.
G= 6.67 * 10⁻¹¹ N*m²/kg²m₁ = 5.97 * 10²⁴ kg m₂= 1.99 * 10³⁰ kg r= 1.48 *10¹¹ mSubstitute the values into the formula.
\(F_g = \frac{ (6.67*10^{-11} N*m^2/kg^2)(5.97*10^{24} \ kg)(1.99*10^{30} \ kg) }{ (1.48 *10^{11} \ m)^2}}\)
Multiply the numerator. The units of kilograms cancel.
\(F_g = \frac {7.9241601 *10^{44} \ N*m^2}{ (1.48 *10^{11} \ m)^2 }\)
Solve the exponent in the denominator.
\(F_g= \frac {7.9241601 *10^{44} \ N*m^2}{ 2.1904*10^{22} \ m^2}\)
Divide. The units of meters squared cancel.
\(F_g=3.61767718 *10^{22} \ N\)
The original values all have 3 significant figures, so our answer must have the same. For the number we found, that is the hundredth place. The 7 in the thousandth place tells us to round the 1 up to a 2.
\(F_g \approx 3.62 *10^{22} \ N\)
The gravitational force between Earth and the Sun is approximately 3.62 *10²² Newtons.

The Earth's surface also absorbs some of the incoming solar radiation and radiates it back out as heat, which is balanced by the radiation of heat energy from the Earth's atmosphere and surface back to space. This balance ensures that the Earth's temperature remains relatively stable over time, and is crucial for maintaining the habitability of the planet.
