An approximately spherical, black asteroid (emissivity equal to one) of diameter 2km is orbiting the sun at a distance from the sun 10 times larger than the distance from the sum to the earth

a) What is the tempature of this asteroid?

b) What is the wavelength of radiation it emits with maximum intersity?

c) What rediation intersity emitted by the asteroid would be observed on Earth (when the asteroid makes its closet approach, assuming a circular orbit)?

Solar constant (solar power per unit area measured above the earth's atmosphere is 1400 W/m^2).

Distance from the Sun to the Earth is 1.5*10^11m

A spherical motile bacteria with a radius of 1.0 microns and a density approximately equal to water is swimming in water (temperature 20 C) at a speed of 8.0 microns per second. The bacteria suddenly stops swimming. Since the Reynolds number for a swimming bacteria is small, it should experience Stokes drag (F?D? = 6????Rv). (a) How long (in seconds) does it take the bacteria to come to a “complete” stop? We’ll define a “complete” stop to be when the...
