A caddie at a golf course must move two sets of golf clubs (on wheels) from the first tee to the second. Will they do more work by wheeling them there both at once or one at a time? I think the caddy is doing more work by wheeling them separately, but if it's the other way around can you please explain!

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation

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,?
