Answer:
1. bending of light in gravitational fields.
2. effect of gravitational redshift.
3. perihelion precission of mecury.
Explanation:
1 bending of light in gravitational fields, we can think of it like this:
by noting the change in position s of stars as they pass near the sun on the celetial sphere, so since the sun creates a gravitational field even the star thats not in our line of side(behind the sun) can be seen because its light is bent.
2. effects of gravitational redshift:
this says that if you are in the gravitational field, your clock moves slower when it is seen by a distant observer.
3. perihelion precission of mecury:
according to Newtonian physics a two body system consisting of a lone orbiting the spherical mass would trace out an ellipse with the center of mass of the system as the focus but mercury deviates from that precission. then according to Einstein, the change in orientation of the orbital ellipsewithin its orbital plane is the effect of gravitation being mediated by the curvature of space-time.
Answer:
Net force equals 0
Explanation:
Newton's first law states that an object at rest tends to remain at rest, and an object in motion tends to remain in motion with a constant velocity (constant speed and direction of motion), unless it is acted on by a nonzero net force. Note that the net force is the sum of all the forces acting on an object.
Well I would assume it would increase due to the increase in body movement creating more energy
During photosynthesis, light energy is converted into an electron flow in the reaction center chlorophyll.
<h3>What is photosynthesis?</h3>
Photosynthesis can be defined as a biological and chemical process through which green plants (autotrophs) convert light energy (sunlight) into chemical energy.
<h3>The chemical reaction for photosynthesis.</h3>
In Science, photosynthesis is represented by the following chemical reaction:

In conclusion, the electrons found within the pigment molecules are excited by visible light, which is then converted into an electron flow in the reaction center chlorophyll.

Answer:
D) 4.9 m/s
Explanation:
Speed of Object in Free Fall
s = Rate of Acceleration, Due to Gravity × Length of Time
s = 9.8 × 2.0
s = m/s (Round Up to The Nearest Whole Number)
--
m/s = 9.8 ÷ 2.0 = 4.9 m/s
