3. The gravitational force between two objects (mass1 = 8 kg, mass2 = 4 kg) is measured when the objects are 10 centimeters apart. If the 8 kg mass is replaced with a 4 kg mass and the 4 kg mass is replaced with a 8 kg mass, how does the new gravitational attraction compare to the first one that was measured?

The simple interest on a loan of $200 at 10 percent interest per year is $10 per year until the loan is paid off. $15 per year until the loan is paid off. $20 per year until the loan is paid off. $25 per year until the loan is paid off.

What object a collides with object b and bounces back its final momentum is?

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.
