Amass m1 of 1610 kg is fixed in place on a frictionless surface at a distance l = 11.9 mm from a second mass m2 of 116 kg. mass m2 is free to move. the surface is slowly tilted. m l θ 2 µ = 0 m1 at what angle of inclination will the second mass begin to slide down the plane? the acceleration of gravity is 9.8 m/s 2 and the value of the universal gravitational constant

6–55 refrigerant-134a enters the condenser of a residential heat pump at 800 kpa and 358c at a rate of 0.018 kg/s and leaves at 800 kpa as a saturated liquid. if the compressor consumes 1.2 kw of power, determine (a) the cop of the heat pump and (b) the rate of heat absorption from the outside air.

The act of moving from one place to another. a. locomotor b. aerobic c. stationary d. static

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
