The same ball is shot straight up a second time from

The same ball is shot straight up a second time from the same gun, but this time the spring is compressed only half as far before firing. How far up does the ball go this time? Neglect friction. Assume that the spring is ideal and that the distance by which the spring is compressed is negligible compared to H.

Assume: The resistance per length of the wire is 0.122 Ω/m.

Assume: The resistance per length of the wire is 0.122 Ω/m. The two-loop wire circuit is 98.6271 cm wide and 65.7514 cm high. The wire circuit in the figure is located in a magnetic field whose magnitude varies with time according to the expression B = (0.001 T/s) t and its direction is out of the page. When the magnetic field is 0.3 T out of the page, find the magnitude of the current through the middle leg P Q of the circuit. Answer in units of μA. The direction of the current in the middle leg of the circuit is from P to Q, or Q to P?
