Anegatively charged object is placed within a positive electric field. what happens to the object?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

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.

The solid that is formed and usually sinks to the bottom of a solution is the
