During the pyramid-building era the ancient Egyptians used two units of length, the palm and the ell. An ell was 7 palms and a palm was about 3 inches. If a hawk is tracked at a diving speed of 3 ells per second, what is its speed in inches per second? 1. 42 in/s 2. 5.25 in/s 3. 0.7 in/s 4. 126 in/s

When does your body conduct current more readily?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
