Consider a planet that, given its albedo and distance from the sun, should have a surface temperature of 100 k, but instead has a surface temperature of 110 k because it has an internal source of heat. how much more energy is the planet emitting than receiving?
a. 1.10
b. 1.21
c. 1.46
d. 2.14

Along, straight wire with 3.0 a current flowing through it produces magnetic field strength 1.0 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 36.0% of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire
