Answer:
0.08 solar masses
Explanation:
0.08 solar mass is required to support nuclear fusion.
As the latitude increases the intensity of solar energy decreases
D. A physical change
The makeup of it is still the same it's just ground up
Answer:

Explanation:
Using kinematics equations:

Use
due to condition of distance traveled.
Solving second equation for time, there are two solutions. t=0 and

Use the expression in the first equation to have

Using trigonometric identities, you have the answer of the distance.
By doing the ratio for two different angles, you have the second answer. Due to sine function properties, the distances can be the same to complementary angles. Example, for 20° and 70°, the distance is the same.
