An object is released into the air to free fall for 12 seconds before hitting the ground. If friction and air resistance are negligible, compare the kinetic, potential,

What are the applications of electromagnetic waves

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.
