An 80 kg worker stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale reads 960 N. Find the magnitude of the elevator's acceleration. (Use g=10m/s^2)

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

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.)

Heterogeneous mixture with larger particles that never settle is
