The form of energy that can move from place to place across the universe is (gravitational potential energy, radiant energy, thermal energy, vibrational energy). on earth, the main source of this energy is (lightning, the moon, the sun, wind).

1.  Radiant Energy is the correct answer.

Radiant Energy is the form of energy that can move from place to place across the Universe. It is y is  electromagnetic energy that travels in transverse  waves.

2.  The sun is the correct answer.

On Earth the main source of energy is the Sun. The sun is the source of all energy (except Nuclear energy) on the earth.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
