The last one , I’m pretty sure is the correct answer .
Answer:
The mass of ball C is greater than the mass of ball A but less than the mass of ball B.
Explanation:
From Newton's second law, net force = mass × acceleration.
Using the data for ball B, the acceleration of gravity near the surface of the moon is:
∑F = ma
9.6 N = (6 kg) a
a = 1.6 m/s²
Therefore, the mass of ball C is:
∑F = ma
6.6 N = m (1.6 m/s²)
m = 4.1 kg
Answer:
Violet Light
Explanation:
On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow.
Answer:
Energy gained by the second particle = 12Uo
Explanation:
Given Data;
Resistant force = 12F
Initial kinetic energy = Uo
Calculating the kinetic energy gained, we have;
u = f *r
where f= resistant force = 20F
r = initial kinetic energy = Uo
Therefore,
U = 12 * uo
= 12 Uo
Therefore, energy gained by the second particle = 12Uo
