(a) The power of the bulb is P=60.0 W. Half an hour corresponds to a time of
so the energy used by the bulb during this time is
(b) The efficiency of the bulb is 12%, it means that it converts only 12% of the input energy into thermal energy, so the thermal energy is

Answer:
C. relatively large size
Explanation:
Earth's internal heat flow to the surface is 80% due to mantle convection while the remaining heat mostly originates in the Earth's crust and about 1% due to volcanic activity, earthquakes, and mountain building.
The earth's internal heat- stresses between the lithosphere and the upper mantle are responsible
for geological processes. These stresses are the results of motions in the upper mantle stemming from convection that push the lithosphere in different directions.
Larger planets cool slower than small planets.
Explanation:
As temperature increases additional heat energy is applied to the consituent part of a solid which cause additional molecular motion.
