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:
10. 3
11. 1
12. 3
Explanation:
10. Everybody has different things that they find stressful. Stressful situations are associated heightened anxiety, fear, and worry. Different situations and life events can trigger stress. Public speaking is a good example of a stressful situation, as it often makes people nervous and uncomfortable. The other options are not usually associated with stress
11. After division of a cell containing 46 chromosomes (diploid), the genetic content is divided equally between 2 cells, producing two daughter cells with 23 chromosomes (haploid). Sex cells are the only cells in the body that are haploid. At fertilisation, 2 haploid cells come together to form a diploid cell.
12. After the whales died, the bones settled in the ocean sediments that moved with the changing land. The bones would not be preserved after animal activity or floating in the ocean. Options 4 and 5 do not explain how the whale bones ended up out of the water.
Answer:
The mass of the object, its acceleration due to gravity and the distance between the top of the hill and the ground level.
Explanation:
gravitational potential energy is the energy possessed by a body under influence of gravitational force by virtue of its position.
In order to determine the gravitational potential energy of the brick, we must know the mass (m) of the brick, its acceleration due to gravity (g) since it is acting under the influence of gravitational force and the distance between the top of the hill and the ground level. (The height).
Potential energy of a body is calculated as mass × acceleration due to gravity × height.
