To calculate work done on an object, a. multiply the force in the direction of motion by the distance the object moved b. multiply all forces applied to the object by the distance the object moved c. divide the force in the direction of motion by the distance the object moved d. divide the distance the object moved by the force in the direction of motion

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

70 give a real life example showing how sensory neurons work with the motor neurons

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,?
