at the surface of the red super giant star betelguese, the gravitational force 6-67x10
between the star and a 1.00 kg mass of hot gas is only 2.19 x 10-3 n. this is
because the mean radius of betelguese is so large. given that the mass of
betelguese is 20 times that of the sun, or 3.98 x 1031 kg, what is the mean radius of
betelguese?

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface
