A ball is thrown upward with a speed of 30 m/s. Approximately how much time does it take the ball to travel from the release location (A) to its highest point (B)? Approximately how much total time is the ball in the air before it returns back to its original height (C)?

Which accurately compares concave and convex lenses?

What determines the amount of inertia an object has

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
