Amass m = 0.7 kg is released from rest at the origin 0. the mass falls under the influence of gravity. when the mass reaches point a, it is a distance x below the origin 0; when the mass reaches point b it is a distance of 6 x below the origin 0. what is vb/va?

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

Carbon-14 is a radioactive element that undergoes beta decay. which force is responsible for allowing carbon-14 to become stable? electromagnetic gravitational weak nuclear strong nuclear

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.
