The tune-up specifications of a car call for the spark plugs to be tightened to a torque of 47 n⋅m . you plan to tighten the plugs by pulling on the end of a 25-cm-long wrench. because of the cramped space under the hood, you'll need to pull at an angle of 115 ∘ with respect to the wrench shaft.
with what force must you pull?

Water at room temperature of 20.0°c is poured into an aluminum cylinder which has graduation markings etched on the inside. the reading in the graduations is 300.0 cc. the cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100°c. what is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? the volume coefficient of expansion of water is 2.07 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc
