The Sun is 864,400 miles across. its about 109 times the diameter of Earth<span>. so the volume is about 109 times the volume of the earth.</span>
Explanation:
The angle of the handle relative to the horizontal is 35°. The angle of the ramp to the horizontal is 7°. So the angle of the handle relative to the ramp is 28°.
cos 28° = 50 / F
F = 50 / cos 28°
F = 56.6 lbs
Potential energy is the greatest when the the kinetic energy is the least. This occurs when the ball loses the energy to fly higher, and begins to fall back to the ground.
THe loss of 2 protons and 2 neutrons (also called a helium nucleus) is defined as alpha decay.
