Use g = 9.8 m/s2 Calculate answer to two decimals.a) When rebuilding his car's engine, a physics major must continuously exert 3.74 x 102 N of force to insert a dry steel piston as it slides into a steel cylinder. What is the normal force (in N) between the piston and cylinder? (Enter the magnitude.) 1246.67 N b) What force (in N) would he have to continuously exert if the steel parts were oiled? (Enter the magnitude.) 187 X NTwo circular platforms are attached to a fluid reservoir. On one platform rests the entire cast of Glee frozen in carbonite. A force of 7.0 N is applied downward to the empty platform with radius 8.0 m. The other platform applies a force of 7.2 N to the carbonite-frozen pop-idols. What is the radius of the platform holding the Glee cast?

What is the average density (in kg/m3) of a uniform-diameter log that floats with 28.0% of its length above water?On a distant planet, where the gravitational field strength is 10.0 N/kg, a block of mass 20 kg hangs from the end of a 5-m fishing boon of mass 14 kg. A cable is attached to the boon two meters from the pivot at an angle of 53º. The submerged block has a mass of 20 kg, but the tension in the rope supporting it is only 140 N (because of the buoyant force). T₂ = T₂=? 53⁰ (a) The tension, T2, in the cable is: Volblock 5 m water mmmmmmmm 3 m N (± 5N) T₁= 140 N 2309 (b) What is the volume of the block?
