earnstyle [38]3 years ago
8 0

Answer:

Explanation:

The equation for momentum is p = mv; therefore,

p1 = 50(4) so

p1 = 200

p2 = 50(5) so

p2 = 250

The impulse, the change in the momentum, is 50, going in the same direction.

melisa1 [442]

Answer:

E

Explanation:

From the equation describing the Electric field strength of a charge

E=F/q

We can deduce that the electric field strength is dependent on the force arcing on the magnitude of the charge.

As the force increases the the electric field increases, also the electric field strength decreases with increasing charge.

Hence the distance has no effect on the electric field strength. The magnitude remain as E

The sunlight that reaches Earth is generated by a transformation of _____.
Georgia [21]

nuclear energy

Explanation:

The sunlight that reaches earth is generated by a transformation of nuclear energy. Radiant energy is a from of energy that reaches the earth from nuclear reactions in the core of the sun.

  • In this process, light nuclei combines to form larger ones through the process of nuclear fusion.
  • This process does not conserve energy and mass is converted to energy.
  • The nuclear reaction produces huge energy that goes into the solar system space and lights it up.
  • Therefore, it is a transformation of nuclear energy into radiant energy.
  • The radiant energy is made up of electromagnetic radiations.
