On the moon, the acceleration due to the effect of gravity is only about 1/6 of that on earth. an astronaut whose weight on earth is 570 n travels to the lunar surface.
(a) what is his weight as measured on the moon? (in newtons)
(b) what is his mass on the moon (in kg)?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

What is a costume plot? why is it important to a film or theater production?

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
