Answers
Answer:
C
Explanation:
It would have to be a bus with a ramp.
Think about it, an inclined slope is kinda like a right triangle, and its a ramp, ramps go down :)

A rock is thrown straight up from the surface of the Earth. Which one of the following statements describes the energy
transformation of the rock as it rises? Neglect air resistance.
a) The total energy of the rock increases.
b) The kinetic energy increases and the potential energy decreases.
c) Both the kinetic energy and the potential energy of the rock remain the same.
d) The kinetic energy decreases and the potential energy increases.
e) Both the potential energy and the total energy of the rock increase.
Answers
Answer: d
Explanation:
Uuhhh I’m not good at explanations...
The kinetic energy decreases while the potential energy increases.
Option d is the answer because as soon as this ball gets thrown from the surface of the earth kinetic energy would be at its greatest.
we have
[tex]k=\frac{1}{2} mv^{2}[/tex]
The velocity is going to be minimized. As the ball is going up its velocity would be falling or decreasing due to gravity. [tex]k=\frac{1}{2} mv^{2}[/tex] would then have a smaller value. So kinetic energy is reducing/decreasing.
We have potential energy as u = m*g*h = 0. This is because the height is 0 as the ball is released. But as the ball goes up, the height would start to increase so the potential energy increases.
In conclusion as the ball is thrown straight from the earth, kinetic energy decreases and potential energy increases.

The kinetic energy of the pom-pom came from potential energy in the system.
How did potential energy gets stored in the spring/pom-pom system?
Answers
Answer:
I believe that the answer is that in physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field.
The elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.
The potential energy stored in a spring is known as elastic potential energy. The elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.
For example, when a spring is compressed it acquires potential energy which will be converted to kinetic energy of the object impacted by the spring.
The elastic potential energy of spring is given as;
[tex]U_x = \frac{1}{2}kx^2[/tex]
where;
k is the spring constantx is the extension of the spring.Thus, we can conclude that, the elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.

Roxanne is an expert at blowing bubbles with bubble gum. She discovered that her bubbles were bigger if she stood facing the Sun when she blew them. At lunch she told her three best friends about her discovery and after school they all tried it. No one else was able to blow bigger bubbles when they faced toward the Sun. Which of the following would be best for Roxanne to do next? A. She should prove she is right by blowing bubbles while her friends are watching.
B. She should give them each bigger pieces of bubble gum and try it one more time.
C. She should think about what else she is doing that might have made the bubbles bigger.
D. She should ask her friends to try it again and concentrate harder when they face the Sun.

NASA plans to launch a new satellite to orbit the Earth. As the satellite is launched the thrust of the hot exhaust gas is pushed through the rocket nozzle and is accelerated toward the rear of the rocket. In turn, the rocket engine is then lifted off of the ground. According to Newton's 3rd law of motion, which statement below is true of the forces involved?
A The downward force exerted by the exhaust on the engine is greater.
B The magnitude of both forces is equal to zero acting in opposite directions.
C Both forces are equal in magnitude, but opposite in direction.

Why would the crash affect the motion of the satellite? Write at least 1 paragraph and good vocab.
Answers
Answer:
The speed and direction of the two satellites would differ from each other cause the asteroids differ in size. The bigger one would have moved the satellite farther of track and go a bit faster than the other asteroid. The other one wont move it as far and the speed would not change by much.
