Explanation:

Given, the position of an object in circular motion is modeled by the parametric equations: x = 5 sin(t) and y = 5 cos(t).

To describe the path of the object:

Radius of the circle:

We can obtain the radius of the circle by using the relation: r² = x² + y²=> r² = (5sin t)² + (5cos t)²=> r = 5Position at time t = 0:

When t = 0, we have x = 5 sin(0) = 0 and y = 5 cos(0) = 5.

The position of the object is at (0, 5) at time t = 0.

Orientation of the motion: We know that sin and cos functions are periodic with period 2π radians.

Hence, we can say that the object completes one revolution around the circle in 2π seconds.

Since x = 5 sin(t) and y = 5 cos(t) represent the equations of a circle with radius 5, it is clear that the path of the object is a circle with center at (0,0) and radius 5 units.

The orientation of the motion is counterclockwise.

Therefore, the path of the object is a circle with center at (0,0) and radius 5 units. The position of the object at time t = 0 is (0, 5).

The orientation of the motion is counterclockwise.

The time t it takes to complete one revolution around the circle is 2π seconds.

Explanation:

Efficiency is a way of describing the amount of useful ​output​ a process or machine can generate as a percentage of the ​input​ required to make it go. In other words, it compares how much energy is used to do work versus how much is lost or wasted to the environment. The more efficient the machine, the less energy wasted.

For example, if a heat engine is able to turn 75 percent of the fuel it receives into motion, while 25 percent is lost as heat in the process, it would be 75 percent efficient. Out of the original 100 percent of the fuel, 75 percent was output as useful work.

The object with the highest mass is the one on planet D. This is because mass is a measure of the amount of matter an object contains, and is not affected by gravity. Therefore, although the weight of the object on planet D is lower than that of the other planets, its mass remains the same.

Weight, on the other hand, is a measure of the gravitational force acting on an object. Therefore, the weight of an object will vary on different planets due to different gravitational forces. As shown in the drawings, the object on planet A has the greatest weight, but nevertheless the greatest mass.

In summary, the object with the greatest mass is on planet D, while the object with the greatest weight is on planet A.

Answer:

-0.375 m/s2

Explanation:

To find the acceleration due to gravity in this planet, we can use the Torricelli formula of UALM (uniformly accelerated linear motion):

V^2 = Vo^2 + 2*a*S

Where V is the final velocity, Vo is the inicial velocity, a is the acceleration and S is the total displacement.

With V = 3, Vo = 0 and S = -12, we have:

3^2 = 0^2 - 2*a*12

24a = -9

a = -9/24 = -0.375 m/s2

The H-R diagram, also known as the Hertzsprung-Russell diagram is a graph that demonstrates the relationship between luminosity, temperature, classification, and spectral types of stars. This diagram shows the life cycle of stars. The life cycle of stars begins with their formation, followed by a sequence of changes leading to the death of a star. The location of a star on an H-R diagram enables us to determine the mass, temperature, and luminosity of the star.

The following can be determined from the location of a main-sequence star on the H-R diagram- The position of a star on the H-R diagram is determined by the star's mass. More massive stars are placed to the left of the diagram, while less massive stars are placed on the right. Temperature can be calculated by looking at where the star falls on the horizontal axis of the H-R diagram. The temperature ranges from cool to hot, left to right.

Answer:

Atom has become a cation.

Atom has lost 2 electrons.

Explanation:

Based on the ionic notation of the element or ion given, we can clearly state that the atom has become a cation and it has lost two electrons.

A cation is an atom that has lost electrons to become positively charged.

In a neutral atom, the number of protons and electrons are the same.

Protons are the positively charged particles within an atom.

Electrons are the negatively charged particles.

 When an atom loses electrons, it becomes positively charged because the number of electrons is now more.

Positively charged atoms are called cations.

a. The picture is drawn below

b. KE = 0 at the initial position and PE = 0 at the final position.

c. Using Conservation of Energy, the final speed of the object just before it strikes the ground is 18.8 m/s.

d. The final speed of the object just before it strikes the ground is 18.8 m/s using 1-dimensional kinematics.

e. Law of conservation of energy is easier.

a. Picture:

     Initial position:

               _______________

              |               |

              |    15 kg      |

              |_______________|

     Final position:

               _______________

              |               |

              |               |

              |_______________|

b. KE = 0 at the initial position, as the mass is at rest. PE = 0 at the final position, when the mass has completely fallen to the ground.

c. Using conservation of energy:

The initial energy of the system is all potential energy, which will be converted into kinetic energy just before the object hits the ground. The law of conservation of energy states that the total energy of a system remains constant, so we can set the initial potential energy equal to the final kinetic energy.

Initial potential energy = Final kinetic energy

mgh = \((1/2)mv^2\)

where m = 15 kg (mass), g = \(9.8 m/s^2\) (acceleration due to gravity), h = 18 m (height above the ground), and v is the final speed of the object just before it strikes the ground.

Substituting the values, we get:

\((15 kg)(9.8 m/s^2)(18 m) = (1/2)(15 kg)v^2\)

Simplifying the equation, we get:

v =\(\sqrt{[(2 * 15 kg * 9.8 m/s^2 * 18 m)/15 kg]\)

v = \(\sqrt{[2 * 9.8 m/s^2 * 18 m]\)

v = \(\sqrt{[352.8]\)

v = 18.8 m/s

Therefore, the final speed of the object just before it strikes the ground is 18.8 m/s.

d. Using 1-dimensional kinematics:

We can use the equation of motion for an object under constant acceleration, which relates the final velocity, initial velocity, acceleration, and displacement:

\(v^2 = u^2 + 2as\)

where u = 0 (initial velocity), a = g = \(9.8 m/s^2\) (acceleration due to gravity), s = 18 m (displacement), and v is the final velocity of the object just before it strikes the ground.

Substituting the values, we get:

\(v^2 = 0 + 2(9.8 m/s^2)(18 m)\)

Simplifying the equation, we get:

v = \(\sqrt{[2 * 9.8 m/s^2 * 18 m]\)

v = \(\sqrt{[352.8]\)

v = 18.8 m/s

Therefore, the final speed of the object just before it strikes the ground is 18.8 m/s using 1-dimensional kinematics.

e. In my opinion, using the law of conservation of energy is easier as it involves fewer equations and calculations. It also provides a more intuitive understanding of the problem by focusing on the energy of the system rather than the motion of the object. However, both methods are equally valid and can be used interchangeably to solve the problem.

A drop shot is a soft shot that lands just over the net and falls quickly, making it difficult for the defense to reach and return. In this situation, the drop shot can be effective because it would require the X players to quickly move forward from the backcourt, putting them out of position and giving the offense an opportunity to score.

Based on the position of the X players, it looks like the back of the court is more crowded compared to the front. Therefore, the offense should aim for an Drop Shot to try to score.

Answer:

1.6 m/s

Explanation:

Avg. Speed =  total distance/total time

d1 = speed x time = (2 m/s)(30 s) = 60 m

d2 = (1.5 m/s)(120 s) = 180 m

d-total = 60 m + 180 m = 240 m

t-total = 30 s + 120 s = 150 s

Avg speed = 240 m / 150 s = 1.6 m/s

A full water tank in the shape of a hemispherical bowl of radius 5 m. 5 m. 8.6875 × \(10^5\) J work is required to pump all the water to a height of 5 m 5 m above the tank

The amount of work required to pump all the water in the full water tank of the shape of a hemispherical bowl of radius 5m to a height of 5m above the tank is 8.6875 x \(10^5\) J.

Let us begin by finding the volume of the hemispherical bowl of radius 5 m.

V = (2/3)πr³

where r is the radius of the hemispherical bowl.

Substituting r = 5 m in the above formula for volume,

we get

V = (2/3) × π × 5³ m³ = 523.6 m³

Since the bowl is full of water, the volume of water it contains is also 523.6 m³.

To find the mass of the water in the bowl, we need to multiply the volume by the density of water at room temperature, which is 1000 kg/m³.

Mass of water in the bowl = 523.6 × 1000 kg = 523600 kg

The potential energy of the water when it is lifted to a height of 5m above the tank is given by

mgh

where m is the mass of water, g is the acceleration due to gravity and h is the height of the water above the tank.

Substituting the given values, we get

Potential energy of water = 523600 × 9.81 × 5 J = 25690800 J

Therefore, the amount of work required to pump all the water to a height of 5m above the tank is equal to the potential energy of the water, which is 25690800 J, rounded off to 8.6875 × 10^5 J.

The answer is C.19.8 m/s because it's their common velocity after the collision of the two cars.

Explanation:

Hello !

look at the attachment above ☝️ and if you have any questions you're welcome.

If a car travels a distance D before stopping, it will go 3D distance before stopping, and If car B stops in time T, car A will take (T/3) time to stop.

(a) The intial speed of car A and B is Ua =  Ub

The final speed of both cars is 0.

Va = Vb = 0

If the displacement of B is Sb

By using the equation of motion:

v² = u² - 2as

v = 0

u² =  2as

2aASA = 2aBSB

SB = (aASA)/(aB)

= 3aBD/ aB = 3D

Car B will go 3D distance.

(b) Using the equation of motion

Ua = Ub

aAtA = aBtB/ aA

= aBT/ 3aB

= T/3

Car A will take (T/3) time to stop.

Answer:

v = 21.25 km/h

The average velocity is 21.25km/h

Explanation:

Average velocity = total displacement/time taken

v = d/t

Given;

A car travels 50 km in 25 km /h

d1 = 50km

v1 = 25km/h

time taken = distance/velocity

t1 = d1/v1

t1 = 50/25 = 2 hours

and then travels 60km with a velocity 20 km/h

d2 = 60km

v2 = 20km/h

t2 = d2/v2 = 60/20

t2 = 3 hours

and then travels 60km with a velocity 20 km/h in the same direction

d3 = 60km

v3 = 20km/h

t3 = d3/v3 = 60/20

t3 = 3 hours

Average velocity = total displacement/total time taken

v = (d1+d2+d3)/(t1+t2+t3)

v = (50+60+60)/(2+3+3)

v = 170/8

v = 21.25 km/h

The average velocity is 21.25km/h
