<h2>Hello!</h2>
The answer is: B. Kinetic energy
<h2>
Why?</h2>
Since the ball is falling, speed increases because the gravity acceleration is acting. When speed increases, the kinetic energy increases too, so the ball is gaining kinetic energy.
The gravity acceleration is equal to 
, it means that when falling, the ball will increase it's speed 9.81m every second.
We can calculate the kinetic energy by using the following formula:

Explanation:
Orbital period = 2 x 10⁶s
Total radius = 2.5 x 10¹²m
Unknown:
Tangential speed of the satellite = ?
Solution:
The tangential speed simply expresses the rate at which the distance moves around its orbit with time.
Since the orbit is taken to be circular;
Tangential speed = 
r is the radius
t is the time or orbital radius
Tangential speed = ![\frac{2 x 3.14 x 2.5 x 10¹²}{2 x10[tex]^{6}](https://tex.z-dn.net/?f=%5Cfrac%7B2%20x%203.14%20x%202.5%20x%2010%C2%B9%C2%B2%7D%7B2%20x10%5Btex%5D%5E%7B6%7D)

Tangential speed = 7.85 x 10⁶m/s

Answer: A hot lightbulb gave off white visible light instead of ultraviolet light.
Explanation:
Without the fig, we know nothing about AB, C_1, C_2, V_a, or V_b.
The probability of getting any kind of answer from anybody who hasn't
seen or tasted the fig is vanishingly small.
