A 6.2kg bucket of water is raised from a well by a rope. If the upward acceleration of the bucket is 5.0m/s^2 find the tensional force exerted by the rope on the bucket of water

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.
