One of them would be power source.
Answer: Stage 1- Stars are born in a region of high density Nebula, and condenses into a huge globule of gas and dust and contracts under its own gravity. This image shows the Orion Nebula or M42 . Stage 2 - A region of condensing matter will begin to heat up and start to glow forming Protostars.
Explanation:
It’s due to the refraction of light rays as they traverse the boundary between water and air. The greater the viewing angle, the more the bending of the light and therefore the less the apparent depth. An object placed in a denser medium, when viewed from rarer medium appears to be at a lesser depth than its real depth due to refraction of light.
Stationary at rest or moving with constant motion
Explanation:
If the force acting upon an object are balanced, the object must be stationary or at rest or moving with constant velocity.
According to newton's first law of motion;
"An object will remain in its state of rest or of uniform motion unless acted upon by an external force".
This suggests that body at rest has balanced forces acting upon it.
