Asmall spinning asteroid is in a circular orbit around a star, much like the earth's motion around our sun. the asteroid has a surface area of 7.70 m2. the total power it absorbs from the star is 3800 w.
assuming the surface is an ideal absorber and radiator, calculate the equilibrium temperature of the asteroid (in k)

Temperature will be 305 K  

Explanation:

We have given The asteroid has a surface area

Power absorbed P = 3800 watt

Boltzmann constant

According to Boltzmann rule power radiated is given by

So temperature will be 305 K  

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
