While rotating around Earth the Moon also rotates around it's axis. These two rotations have almost same duration (27.3 and 27 days respectively). This is the reason why we always see the same side of Moon.
The dark part of a Moon is the part where there is night on the Moon, meaning there is no sunlight visible. This dark part depends on the Moon's position relative to Earth and Sun. The change in size is due to part of Moon-day. Dark part of Moon has night, bright part has day and the boundary has either sunrise or sunset.
Opaque materials absorb all the light that shines on them. None of it comes out the other side. That's why they're opaque.
Opaque materials become warmer when light shines on them, because <em>they absorb the energy</em> carried by the light that shines on them. (According to the law of Conservation of Energy, that energy has gotta go somewhere.)
Answer:
20 m/s
Explanation:
initial velocity, u= 25m/s
u has two components. one in horizontal and in one vertical.
so,
u sin theta = vertical component.
=> u sin theta = 25× 4/5
= 20 m/s
