The force between a positively charged foam cup and a positively charged metal sphere is 5.2 × 10−4 newtons. The charge on the cup is 7.2 × 10−6 coulombs, and the charge on the metal sphere is 6.8 × 10−6 coulombs. What is the distance between the two objects? (k = 9.0 × 109 newton·meters 2/coulombs2)

Can you match these to the correct definition

Juliette sets the initial velocity to +10 m/s, the acceleration to zero, and clicks “start.” how can shakina describe the subsequent motion of the car juliette controls?

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
