Answer:
A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More p recisely, one light-year is equal to 9,500,000,000,000 kilometers
Answer:
Einstein's equivalence principle says that __________.
the effects of gravity are exactly equivalent to the effects of acceleration
Explanation:
The equivalence principle is one of the fundamental laws of physics, as enunciated by Einstein. It categorically states that the gravitational and inertial forces are of a similar nature. In physics, a gravitational acceleration is the acceleration of an object in a free fall within a space. The importance of Einstein's Equivalence Principle is explained by his theory of general relativity. This theory states that mass is the same, whether inertial or gravitational.
Answer:
C. All planets orbit the Sun in the same direction.
E. The orbits of the planets are evenly distributed in distance from the Sun.
F. All planets orbit the Sun in a roughly flat plane.
Explanation:
As we can see that due to big bang theory of planet formation we can say all planets revolve around the sun in circular orbit with almost in same plane
Size of the planets are unevenly distributed and they all revolve around the sun in same directions
so here correct options are
C. All planets orbit the Sun in the same direction.
E. The orbits of the planets are evenly distributed in distance from the Sun.
F. All planets orbit the Sun in a roughly flat plane.
Answer:
The tennis ball.
Explanation:
Because the baseball is heavier, it requires more force to move it, whereas the tennis ball requires less force, so it will move more. Hope that makes sense!
