If a scientist is studying a model that is a widely accepted theory about the position of planets and sun, the model would most likely help the scientist to understand facts that can't be easily observed. That will make the correct answer to be C.
The velocity of the block leaving the spring is determined as 18.26 m/s.
<h3>
Velocity of the block</h3>
The velocity of the block leaving the spring is calculated from the principle of conservation of energy.
K.E = Ux
¹/₂mv² = ¹/₂kx²
v² = kx²/m
v² = (500 x 2²)/6
v² = 333.33
v = √333.33
v = 18.26 m/s
Thus, the velocity of the block leaving the spring is determined as 18.26 m/s.

Loudness<span> refers to how loud or soft a </span>sound<span> seems to a listener. The </span>loudness<span> of </span>sound is<span> determined, in turn, by the </span>intensity<span>, or amount of energy, in </span>sound<span> waves. The unit of </span>intensity is<span> the decibel (dB). As decibel levels get higher, </span>sound<span> waves have greater </span>intensity<span> and </span>sounds are<span> louder.</span>
It’s B lovey !!! Glad to help
