The Earth spins on its axis and also orbits around the Sun.
For this problem use the following constants.
Mass of the Earth: 5.97 × 10^24 kg (assume a uniform mass distribution)
Radius of the Earth: 6371 km
Distance of Earth from Sun: 149,600,000 km

What is the rotational kinetic energy of the Earth due to its orbit around the Sun, in joules?

The magnitude of the poynting vector of a planar electromagnetic wave has an average value of 0.939 w/m^2 . the wave is incident upon a rectangular area, 1.5 m by 2.0 m, at right angles. how much total electromagnetic energy falls on the area during 1.0 minute?

Consider the growth of a 20-nm-diameter silicon nanowire onto a silicon wafer. the temperature of the wafer surface is maintained at 2400 k. assume the thermal conductivity of the silicon nanowire is 20 wm-1k-1 and all its surfaces including the tip are subjected to convection heat transfer with the coefficient h = 1×105 wm-2k-1 and t∞ = 8000 k. when the nanowire grows to l = 300 nm, what is the temperature of the nanowire tip (t (x =
