Which of the following is NOT an effective way to help prevent further injury once you have been hurt? Group of answer choices

A. Rehabilitating the injured area through stretching

B. Returning to physical activity before injury is fully healed.

C. Allowing proper recuperation time before being physically active again.

D. Receiving appropriate treatment for existing injuries.

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.

Consider motion in one dimension. (the sign of the vector quantities is their direction indicator.) an object moves in the positive x-direction with speed 2.9 m/s for 4.5 s. it stops for 3.8 s and then moves in the negative x direction with speed 2.8 m/s for 4 s. what is the total distance traveled by the object in units of meter? enter a number with two digits behind the decimal point.

5volt is supplied to an electrical circuit.if the resistance of the circuit is 2.5ohms ,calculate the current flowing through the circuit.
