Each round has a muzzle velocity of 2,820 ft/s and a mass of 48.599 g. If the barrel of the rifle is 74 cm, with what force is each bullet fired?

What causes the formation of ocean currents?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

What are some properties of transverse waves?
