Suppose a small plane can fly at 170 km/hr relative to the surrounding air. Suppose also that there is a 60 km/hr tailwind blowing in the same direction as the plane's motion. How fast does the plane's shadow move across the ground

When you turn on a battery-operated device, an electrical circuit is

Chemical energy is a form of energy. a. heat b. kinetic c. potential d. electromagnetic

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,?
