The end of a horizontal rope is attached to a prong of an electrically driven tuning fork that vibrates at 100hz. the other end passes over a pulley and supports a 2-kg mass. the linear mass density of the rope is 0.075 kg/m. what is the wavelength of a transverse wave on the rope?

0.25 m
0.16 m
0.12 m
1.2 m

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.
