Answer:
<em>The Sun produces energy by the process of nuclear fusion. Nuclear fusion occurs when lighter nuclei combine to produce a larger, heavier nucleus. In the process, energy is released. Nuclear fusion requires very high temperatures and pressures. Nuclear fusion occurs in the core of the Sun when hydrogen atoms combine to form helium atoms.</em>

Answer:
I only really know the "How do we use these EM waves in our lives?" part srry
Explanation:
EM waves are used to make sure you cellphone, radio, TV, and etc. have service/ connection.
Answer:
C
Explanation:
Because everything on Earth falls at the same speed, the masses of the balls do not matter. Since the acceleration due to gravity is constant, their speeds will both be increasing at the same rate, and therefore the difference in speeds would remain constant until they hit the ground. Hope this helps!
Answer:
- 144 V
Explanation:
A = (2, 3) m = 2 i + 3 j
B = (5, 7) m = 5 i + 7 j
Displacement vector = AB = B - A = (3 i + 4 j) m
Electric field, E = (4 i + 3 j ) N/C
V = - E . AB
V = - (4 i + 3 j) . (3 i + 4 j)
V = - (12 + 12) = - 144 V
The core of a star must be at the temperature of 10,000,000 degrees Celsius for hydrogen fusion to begin.
