How long did it take the ball to return to the launching height? c. ... A ball is launched with an initial velocity of 4.47 m/s at an angle of ... C. How far away did it land? 5

Explanation: its b

ANSWER:

(a) 0.100 m^3

STEP-BY-STEP EXPLANATION:

We have that the force is equal to mass times gravity, therefore, we can calculate the mass, because the difference in force would be the volume of the stone.

Therefore

Now, we know that the density is equal to the quotient between the mass and the volume, therefore we can calculate the volume like this:

Therefore the volume of the piece is 0.100 cubic meters.

The magnitude of the average voltage induced in the coil is 12.5 volt.

It is the creation of a potential difference in a coil as a result of variations in the magnetic flux flowing through it. To put it another way, it is said that electromotive force, or EMF, is created when the flux connecting with a conductor or coil changes.

Given that: a circular coil with an area of 0.0500 m^2 is wrapped with 500 turns of wire and the magnetic field changes in value from -0.100 T to 0.150 T in an interval of 0.500 s.

Hence, the magnitude of the average voltage induced in the coil is =

N ( B₂ - B₁) A/t

= 500(0.150 - (-0.100))0.0500/0.500 volt.

= 12.5 volt.

As a general rule of thumb, you should wait to exercise until three to four hours after eating a meal, and one to two hours after eating a snack.

How Soon Can You Workout After Eating?

Experts generally advise waiting 3 to 4 hours after a meal and 30 to 90 minutes after a snack. Your meals should be basic and simple to digest as you come closer to your workout. This is from the general rule of thumb.

A quick, readily digested snack should be planned for about an hour before to an intense workout, but if you are undertaking a workout that takes less energy and haven't eaten in four hours, you may be able to forgo the snack.

Density of a planet is a fundamental property that can be used to infer its composition. The belief that a planet with a density of 3.4 g/cm3 is composed mostly of rock with a little iron is based on scientific observations and measurements.

By studying the properties of objects in our solar system, scientists have determined that rocky planets like Earth have densities that are generally in the range of 3 to 5 g/cm3. Iron, which is denser than rock, will increase the overall density of a planet. Therefore, a density of 3.4 g/cm3 is consistent with a composition that is mostly rock with a small amount of iron.

Additionally, scientists use spectroscopic techniques to study the light that is reflected off a planet's surface. By analyzing the light, they can determine the types of minerals present on the surface. On the basis of these observations, it has been concluded that planets with densities around 3.4 g/cm3 are composed of silicate rocks and possibly a small amount of metal.

The balloon carries approximately 3.23 x 10^13 excess electrons.

To determine the number of excess electrons on the balloon, we need to use the elemental charge and the charge on the balloon.

The elementary charge, denoted e, is the charge carried by a single electron and has a magnitude of approximately 1.6 x 10^-19 coulombs.

The charge on the balloon is given as -5.16 nC (a negative charge indicates an excess of electrons).

To calculate the number of excess electrons, we can divide the charge on the balloon by the elementary charge:

Number of excess electrons = (balloon charge) / (elemental charge)

Number of excess electrons = (-5.16 nC) / (1.6 x 10^-19 C)

Calculation of this distribution:

Explanation:

Answer:

The lifeguard should run approximately 17.752 meters along the shore, before, jumping in the water

Explanation:

The given parameters are;

The rate at which the lifeguard runs = 5 m/s

The rate at which the lifeguard swims = 1 m/s

The horizontal distance of the child from the lifeguard = 30 meters along the shore

The vertical distance of the child from the lifeguard = 60 meters along the shore

Let x represent the distance the lifeguard runs

We have;

The distance the lifeguard swims = √((30 - x)² + 60²)

Time = Distance/Speed  

The time the lifeguard runs = x/5

The time the lifeguard swims = √((30 - x)² + 60²)/1

The total time = √((30 - x)² + 60²) + x/5

The minimum time is given by finding the derivative and equating the result to zero, as follows;

Using an online application, we have;

d(√((30 - x)² + 60²) + x/5)/dx = 1/5 - (30 - x)/(√((30 - x)² + 60²)) = 0

Which gives;

1/5 - (30 - x)/(√(x² - 60·x + 4500) = 0

(30 - x)/(√(x² - 60·x + 4500)) = 1/5

5×(30 - x) = √(x² - 60·x + 4500)

We square both sides to get;

(5×(30 - x))² = (x² - 60·x + 4500)

(5×(30 - x))² - (x² - 60·x + 4500) = 0

25·x² - 1500·x + 22500 - x² + 60·x - 4500 = 0

24·x² - 1440·x + 18000 = 0

Dividing n=by 24 gives;

24/24·x² - 1440/24·x + 18000/24 = 0

x² - 60·x + 750 = 0

By the quadratic formula, we have;

x = (60 ± √((-60)² - 4×1×750))/(2 × 1) =

Using an online application, we have;

x = (60 ± 10·√6)/(2)

x = 30 + 5·√6 or x = 30 - 5·√6

x ≈ 42.25 m and x ≈ 17.752 m

At x = 42.25

Time = √((30 - 42.247)² + 60²) + 42.247/5 ≈ 69.69 seconds

At x = 17.75

Time = √((30 - 17.752)² + 60²) + 17.752/5 ≈ 64.79 seconds

Therefore, the route with the shortest time is when the lifeguard runs approximately 17.752 meters (rounded to three decimal places) along the shore, before, diving in the water

1-When two capacitors are connected in series, the equivalent capacitance can be calculated using the formula:

1/Ceq = 1/C1 + 1/C2

where C1 and C2 are the capacitances of the two capacitors.

In this case, C1 = 1500 micro-farad and C2 = 3000 micro-farad. Substituting these values into the formula, we get:

1/Ceq = 1/1500 + 1/3000

1/Ceq = 2/3000

Ceq = 3000/2

Ceq = 1500 micro-farad

When two capacitors are connected in series, the equivalent capacitance can be calculated using the formula:

1/Ceq = 1/C1 + 1/C2\

where C1 and C2 are the capacitances of the two capacitors.

In this case, C1 = 1500 micro-farad and C2 = 3000 micro-farad. Substituting these values into the formula, we get:

Ceq = 3000/2

Ceq = 1500 micro-farad

3-When two capacitors are connected in parallel, the equivalent capacitance can be calculated using the formula:

Ceq = C1 + C2

where C1 and C2 are the capacitances of the two capacitors.

In this case, C1 = 1500 micro-farad and C2 = 3000 micro-farad. Substituting these values into the formula, we get:

Ceq = 1500 + 3000

Ceq = 4500 micro-farad

Therefore, the equivalent capacitance when the 3000 micro-farad capacitor is connected in parallel with the 1500 micro-farad capacitor is 4500 micro-farad.

The energy stored in a capacitor can be calculated using the formula:

\(E = 1/2 * C * V^2\)

where E is the energy stored, C is the capacitance, and V is the voltage across the capacitor.

Let's assume that the voltage across the series combination is V.

For the 1500 micro-farad capacitor:

\(E1 = 1/2 * C1 * V^2 = 1/2 * 1500 * V^2\\\)

For the 3000 micro-farad capacitor:

\(E2 = 1/2 * C2 * V^2 = 1/2 * 3000 * V^2\)

The total energy stored in the series combination is:

\(Etotal = E1 + E2 = 1/2 * 1500 * V^2 + 1/2 * 3000 * V^2 = 2250 * V^2\\\)

Let's assume that the voltage across the parallel combination is V.

The total energy stored in the parallel combination is:

When two capacitors are connected in series, the equivalent capacitance can be calculated using the formula:

1/Ceq = 1/C1 + 1/C2

1/Ceq = 1/1500 + 1/3000

1/Ceq = 2/3000

Ceq = 3000/2

Ceq = 1500 micro-farad

Therefore, the equivalent capacitance when the 3000 micro-farad capacitor is connected in series with the 1500 micro-farad capacitor is 1500 micro-farad.

When two capacitors are connected in parallel, the equivalent capacitance an be calculated using the formula:

Ceq = 4500 micro-farad

The energy stored in a capacitor can be calculated using the formula:

E = 1/2 * C * V^2

where E is the energy stored, C is the capacitance, and V is the voltage across the capacitor.

Let's assume that the voltage across the series combination is V.

For the 1500 micro-farad capacitor:

\(E1 = 1/2 * C1 * V^2 = 1/2 * 1500 * V^2\)

For the 3000 micro-farad capacitor:

\(E2 = 1/2 * C2 * V^2 = 1/2 * 3000 * V^2\)

The total energy stored in the series combination is:

\(Etotal = E1 + E2 = 1/2 * 1500 * V^2 + 1/2 * 3000 * V^2 = 2250 * V^2\)

Let's assume that the voltage across the parallel combination is V.

The total energy stored in the parallel combination is:

\(Etotal = 1/2 * Ceq * V^2 = 1/2 * 4500 * V^2 = 2250 * V^2\\\)

Comparing the total energies stored in the series and parallel combinations, we can see that they are the same:

\(Etotal(series) = Etotal(parallel) = 2250 * V^2\)

This indicates that connecting capacitors in series or parallel does not change the total amount of energy that can be stored.

The Equivalence Principle of Gravity

Explanation:

The fact that objects fall to earth at the same speed is called the Equivalence Principle of Gravity.

According to the Equivalence Principle of Gravity, all things fall at the same rate when there is little to no air resistance. The value of the acceleration caused by gravity is demonstrated by the force of gravity equation to be a constant that is independent of the mass of the item.

According to Einstein's equivalence principle, it is unnecessary to distinguish between gravitational and inertial forces because they are comparable in nature.

Therefore, the Equivalence Principle of Gravity states that all objects descend to Earth at the same rate.

To find the tension that will give a wave speed of 177 m/s, we can use the formula v = √(T/μ), where v is the wave speed, T is the tension, and μ is the linear mass density of the string.

Since μ is constant, we can set up a proportion using the known values and solve for the new tension:
154/√(83.0) = 177/√(T_new)
Square both sides and isolate T_new:
(154^2)/(83.0) = (177^2)/(T_new)
T_new = (177^2 * 83.0) / (154^2)
T_new ≈ 114.86 N

Work is the ability to do something.

a) 2.0 represents the initial position of the ball,  -3.6 represents the initial velocity of the ball  and 1.7 represents the acceleration of the ball.

b)The unit of 2.0 is meters, the unit of -3.6 is meters per second, and the unit of 1.7 is meters per second squared.

c) Position of of ball at t=1, 2, 3 are -1.9, 5.4 and 9.1 meters respectively

d) Average velocity is 5.5 meter per second

Part a

In the equation x = 2.0 - 3.6t + 1.7t2, the number 2.0 represents the initial position of the ball (i.e., the position of the ball at t = 0 seconds), -3.6 represents the initial velocity of the ball (i.e., the velocity of the ball at t = 0 seconds), and 1.7 represents the acceleration of the ball.

Part b

The unit of 2.0 is meters, the unit of -3.6 is meters per second, and the unit of 1.7 is meters per second squared.

Part c

To determine the position of the ball at t = 1.0 s, 2.0 s, and 3.0 s, we simply substitute these values into the equation:

When t = 1.0 s: x = 2.0 - 3.6(1.0) + 1.7(1.0)^2 = -1.9 meters

When t = 2.0 s: x = 2.0 - 3.6(2.0) + 1.7(2.0)^2 = 5.4 meters

When t = 3.0 s: x = 2.0 - 3.6(3.0) + 1.7(3.0)^2 = 9.1 meters

Part d

The average velocity over the interval t = 1.0 s to t = 3.0 s can be calculated by taking the displacement of the ball during this time interval and dividing it by the time interval:

Displacement = x(3.0) - x(1.0) = 9.1 - (-1.9) = 11.0 meters

Time interval = 3.0 s - 1.0 s = 2.0 s

Average velocity = Displacement / Time interval = 11.0 meters / 2.0 seconds = 5.5 meters per second.

The building is approximate - 29.4 meters tall. The negative sign indicates that the brick is below the starting point, so the height of the building is 29.4 meters.

To determine the height of the building, we need to calculate the vertical displacement of the brick. First, let's break down the initial velocity of the brick into its vertical and horizontal components. The initial speed of 35 m/s can be split into two parts: the vertical component and the horizontal component. Since the angle is 45 degrees, both components will have the same value.

Using trigonometry, we can calculate the vertical component of the initial velocity. The vertical component can be found by multiplying the initial speed (35 m/s) by the sine of the angle (45 degrees).
Vertical component = initial speed * sin(angle)
Vertical component = 35 m/s * sin(45 degrees)
Vertical component = 35 m/s * 0.707
Vertical component = 24.5 m/s (approximately)

Now, we know the initial vertical velocity of the brick is 24.5 m/s. Next, we can use the kinematic equation to calculate the vertical displacement of the brick during its flight. The equation is as follows:

Vertical displacement = (initial vertical velocity * time) + (0.5 * acceleration * time²)
Since the brick is thrown upward, the acceleration due to gravity should be negative (-9.8 m/s²).

Plugging in the values, we have:
Vertical displacement = (24.5 m/s * 6 s) + (0.5 * -9.8 m/s² * (6 s)²)
Vertical displacement = 147 m + (-176.4 m)
Vertical displacement = -29.4 m
