The answer is C because its shiny
Answer:
Their common velocity after collision is 3.6 m/s
Explanation:
Given;
mass of the first meatball, m₁ = 3.0 kg
initial velocity of the first meatball, u₁ = 6.0 m/s
mass of the second meatball, m₂ = 2.0 kg
initial velocity of the first meatball, u₂ = 0 m/s
let their common velocity after collision = v
Apply the principle of conservation of linear momentum for inelastic collision ;
m₁u₁ + m₂u₂ = v(m₁ + m₂)
(3 x 6) + (2 x 0) = v( 3 + 2)
18 = 5v
v = 18 / 5
v = 3.6 m/s
Therefore, their common velocity after collision is 3.6 m/s

False, the term seeing is not used to describe the measure of faint an object can be detected.
<u>Explanation:</u>
Astronomers use the term "seeing" to suggest the effect of turbulence created by atmosphere. As per telescopes, the larger the area of telescope, the more accurately it can detect fainter objects. This is because the area of telescope is directly proportional to the light collected in it.
Thus, the term seeing and ability to observe fainter object is completely independent of each other. So, it is a false statement that the term seeing is used to describe how faint an object can be detected by a telescope.
