Work = Force times Distance
W = Fd
Given W = 750J, F = 125N;
750 = 125d
Solving for d:
d = 750/125
d = 6
The box moved a distance of 6 meters.

Time dilation is the slowing of the passage of time at high speeds. The faster the object moves, the greater the amount of time dilation. Time dilation, in part, accounts for the constant speed of light, regardless of the light's source and regardless of the observer's perspective.
D. The net gravitational force on the astronaut is not balanced by a normal force
Rather than reflecting, most sunlight that reaches the ocean's surface passes directly into the ocean. As the light travels through the ocean, it is absorbed and scattered by molecules and particles. Water absorbs light faster when the wavelength is long and the energy is low.
