T1 > T2, because the first rope attached must hold the full weight of the loudspeaker before the second rope is attached.T1 > T2, because rope 1 is shorter than rope 2.T1 = T2, because two ropes attached to the same loudspeaker should have the same tension.T1 = T2, because the ropes attach to the loudspeaker at the same point and at the same angle.SubmitPrevious AnswersCorrectThis is a type of reasoning, used often in physics, called a symmetry argument. Since the ropes are in identical situations, except for one being themirror image of the other, they have to possess identical tensions. Since the two tensions have equal magnitude, just use T to denote the magnitudeof the tension in either rope.

Instructions Click 'start' in the following Active Figure depicting static and kinetic frictional forces with a given applied force to a trash can to complete the exercise. EXPLORE A trash can with a mass of 11 kg has a coefficient of static friction of Ms = 0.88 and a coefficient of kinetic friction of μk = 0.40. (The Active Figure applies to a similar situation, but the values of the mass, coefficient of static friction and coefficient of kinetic friction may be different. So the values it gives may not be the same values you obtain from your calculations.) (A) What is the maximum horizontal force F that can be exerted without moving the trash can? (B) Suppose this force is just barely exceeded. Determine the acceleration of the trash can as it moves. CONCEPTUALIZE The trash can is being pushed near its base but the applied force is balanced by the force of static friction. The maximum force of static friction is determined by the coefficient of static friction and the normal force…
