A force of 10,000 N is applied to a wall that does not move. How much work is performed? Be sure to show your work: write formula, place in values, and solve equation.

=force × distance a. work b. velocity c. pressure d. momentum

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 frequency of the fundamental of the guitar string is 320 hz. at what speed v do waves move along that string?
