A plumber has a 30-cm long wrench and a 60-cm long wrench and is trying to loosen stubborn bolt. Which wrench will allow her to exert more torque, and by how much (assume she applies the same force on both wrenches and at the same angle)? A. The shorter wrench will allow her to exert four times as much torque. B. The shorter wrench will allow her to exert twice as much torque. C. Both wrenches will allow her to exert the same amount of torque. D. The longer wrench will allow her to exert twice as much torque. E. The longer wrench will allow her to exert four times as much torque.

Asatellite that goes around the earth once every 24 hours iscalled a geosynchronous satellite. if a geosynchronoussatellite is in an equatorial orbit, its position appearsstationary with respect to a ground station, and it is known as ageostationary satellite find the radius rof the orbit of a geosynchronous satellite that circles the earth.(note that ris measured from the center of the earth, not the surface.) you mayuse the following constants: the universal gravitational constant g is 6.67 \times 10^{-11}\; {\rm n \; m^2 / kg^2}. the mass of the earth is 5.98 \times 10^{24}\; {\rm kg}. the radius of the earth is 6.38 \times 10^{6}\; {\rm m}.
