Arocket is launched straight up with constant acceleration. four seconds after liftoff, a bolt falls off the side of the rocket. the bolt hits the ground 6.10s later. what was the rocket's acceleration?

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.

Which of these metals are magnetic?
