The narrator of The Jungle Book by Rudyard Kipling portrays the man cub as cute and endearing. How might this characterization be different if Shere Khan were the narrator?
The man cub would be described as a food item, because Shere Khan would want to eat him.
The man cub would be described as friendly, because Shere Khan would want to help him.
The man cub would be described as dangerous, because Shere Khan is scared of humans.
The man cub would be described as smart, because Shere Khan admires human intelligence.
Answer: the answer is C - The man cub would be described as dangerous, because Shere Khan is scared of humans.

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.
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?
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.

If an object has kinetic energy, what must it be doing?
Answer:
It has to be moving in order for it to be kinetic energy and potential energy is when is not moving.
Answer:
The Object Must Be Moving!
Explanation:
Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.

A ball is thrown up into the air. Describe the work done on the ball and the energy transformations that take place
between the time the ball is released and the time it reaches its maximum height.
Answer:
so if the ball is thrown up it will eventually fall right? so what it's asking is how hard and fast the ball is thrown and so the time is released it will go up, and by the time it reaches the maximum height it will fall.
