The acceleration due to gravity on the surface of the moon is 1.62m/s^2. the moon's radius is rm+1738km. a) what is the weight in newtons on the surface of the moon of an object that has a mass of 10kg? b) determine the force extend on the object by the gravity of the moon if the object is located 1738km above the moon's surface.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
