Answer:
the speed of light in air is about 299,000,000 and 3×10⁸ m/s
Answer:
Yes.
Explanation:
Newton's first law says that an object in motion stays in motion and an object at rest stays at rest until acted upon by an unbalanced force.
If an object in motion has balanced forces, it will stay in motion. For example, if an object is falling at terminal velocity (for example, a parachuter), then the force of gravity is equal and opposite to the force of air resistance. The forces are balanced, and the object continues to fall at a constant speed.
Answer:
C and D
Explanation:
an object that is projected at an angle where gravity is the only force acting on the object
