I need this answer too , can someone please help , I have a time limit , please
Answer:
A. Sound comes from the ball every time it bounces.
B. The ball is warmer after it stops bouncing than it was before it
started bouncing
Explanation:
It is evidently shown that the ball shown energy transformation because it produces sound at each bounce and also becomes warmer after the bounce.
The law of conservation of energy suggests that energy is neither created nor destroyed but transformed from one form to another.
- a bouncing ball produces sound energy at each bounce. This is conversion of potential energy initially of the ball into kinetic energy of sound.
- Also, the motion of the ball produces kinetic energy which causes the ball to warm up, this is thermal energy.
- We see that a ball originally with potential energy has yielded the kinetic forms of energy which are sound and thermal energy.
<span>The correct answer is: Option (A) Orange
Explanation:
When two or more colors mixed together, the color of light that is reflected back represents the equivalent color for the different colors you mixed. Let's take white color as an example. If you mixed up all the color of the light spectrum, you will get the white color (which is reflected). Likewise, when red and yellow paints are mixed together, it is the orange color that is reflected. Hence the correct option is (A) Orange.</span>
