An electric dryer consumes 6.0 × 10^6 joules of
electrical energy when operating at 220 volts for
1.8 × 103 seconds. during operation, the dryer
draws a current of
(1) 10. a (3) 9.0 × 102 a
(2) 15 a (4) 3.3 × 103 a

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
