Identify the force that moves a rock upwards

electromagnetism. (more info below)

Explanation:

Electromagnetism is the basic energy that propels a rocket. What is occurring is that any chemical reaction (the burning) gives fuel particles a fast speed and these are expelled from the rocket at the edges. As the momentum needs to be maintained and such particles have a net downward momentum (particles traveling upward clash with the rocket), a net upward momentum is obtained.

hope this helped!

The correct answer is option(d).

Explanation:

The light given by the combination of the all the seven colors is white color.

Generally white light splits into the band of seven colors when passed through the prism which is known as spectrum.

When the Anna shines a beam of light that includes all the wavelengths of visible light onto the wall she will observe the white light on the wall of the darken room.

Hence, the correct  option is (d).
