A hologram is a physical structure that diffracts light into an image. The term ‘hologram’ can refer to both the encoded material and the resulting image. A holographic image can be seen by looking into an illuminated holographic print or by shining a laser through a hologram and projecting the image onto a screen. Hope this helps! Oh and here's a good source to use just don't forget to credit the sources you use.

Answer:
The acceleration of gravity on the Moon is only one-sixth of that on Earth. If we hit a baseball on the moon with the same effort(and at the speed and angle)that we would on earth, the ball would land 6 times as far. The ball on the moon will cover 6 times more distance than Earth.
Explanation:
Speed=distance travelled/Time required speed
Speed=d/t
Acceleration of gravity on earth=9.8 m/s^2
Acceleration of gravity on Moon=1.62 m/s^2
So the maximum height of ball will be the ration of these both gravity.
Answer: (D)
