Answer:
It will be A. So since its 2 times more the kinetic energy. But then you have to square it 2^2 = 4
Answer:
that's nice very nice super duper nicer
Given mass = 2kg, height = 10m,g = 9.8.
We know that Work done W = FD
= > W = (mg)(D)
= > W = (2 * 9.8)(10)
= > W = 196 Joules.
Hope this helps!
Distances to nearby stars can be determined from Stellar parallax. <span>Astronomers can measure a star's </span>position<span> once, and then again 6 months later and calculate the apparent change in </span>position<span>. The star's apparent motion is called stellar parallax. The distance d is measured in </span>parsecs<span> and the parallax angle p is measured in </span>arcseconds<span>.</span>
