How much pressure do you experience when you balance a 0.63 kg basketball on the tip of your finger assuming a contact area of 1 cm^2 (1 x 10^-4 m^2). Recall P = F/A and 1 Pa = 1 N/m^2. a) In Pascals (Pa) and b) In kilopascals (kPa)

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.

Which composition of water moves to begin a deepwater current?

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.
