A, B, and C are all incorrect because they are talking about springs. I'm assuming you're talking about a 2 dimensional, side to side pendulum. In that case, the answer is D because as the pendulum goes up from one side, gravity accelerates it downward until it swings to the other side. If you're not talking about this type of pendulum, leave a comment and ill come back.
E = hf
E = 6.63* 10 ⁻³⁴ * 7.24* 10¹⁴
<span>E = 4.80012 × 10⁻¹⁹ J</span>
Answer:
5/6 = 0.833
Explanation:
From conservation of momentum,
m1*u1 + m2*u2 = (m1+m2)*v
v = (m1*u1 + m2*u2)/(m1*m2)
Putting in the values, we get, v = 5/6 = 0.833
