Answer:
v = √k/m x
Explanation:
We can solve this exercise using the energy conservation relationships
starting point. Fully compressed spring
Em₀ = 
= ½ k x²
final point. Cart after leaving the spring
= K = ½ m v²
Em₀ = Em_{f}
½ k x² = ½ m v²
v = √k/m x
Answer: (A) "X: May use LF, HF, and UHF waves
Y: Travels at the speed of light
Z: May use MF and VHF waves"
High mass are largest , hotest , and brightest sequence
An element like that would have have a molecular structure that has a high tolerance to heat, so the correct answer is D
