A satellite becomes unstable in its orbit and begins to fall towards earth and simultaneously starts burning. If the satellite had a potential energy of 10000 J initially and by the time it reaches the surface of the earth it attains a kinetic energy of 5000 J, then how much energy was lost as a result of its burning?

Solution

The correct option is C
5000 J

Potential energy is converted to kinetic energy and heat energy.
So 10000 J = 5000 J + heat energy
Therefore, heat energy = 10000 - 5000 = 5000 J

The correct option is C 5000 J Potential energy is converted to kinetic energy and heat energy. So 10000 J = 5000 J + heat energy Therefore, heat energy = 10000 - 5000 = 5000 J

The correct option is C
5000 J

Potential energy is converted to kinetic energy and heat energy.
So 10000 J = 5000 J + heat energy
Therefore, heat energy = 10000 - 5000 = 5000 J
