Consider two point particles that have charge +e, are at rest, and are separated by 2.7 x 10-15 m.

1) how much work was required to bring them together from a very large separation distance? kev

2) if they are released, how much kinetic energy will each have when they are separated by twice their separation at release? kev

3) the mass of each particle is 1.00 u (1.00 amu). what speed will each have when they are very far from each other? m/s

Iflow from a warmer object to a cooler object until both objects are the same temperature what am i?

In a wind tunnel the speed changes as the cross sectional area of the tunnel changes. if the speed in a 6' x 6' square test section is 100 mph, what was the speed upstream of the test section where the tunnel measured 20' x 20'? use conservation of mass and assume incompressible flow. conservation of mass requires that as the flow moves through a path or a duct the product of the density, velocity and cross sectional area must remain constant; i.e., that ova-constant. a model is being tested in a wind tunnel at a speed of 100 mph if the flow in the test section is at sea level standard conditions, what is the pressure at the model's stagnation point? (a) the tunnel speed is being measured by a pitot-static tube connected to a u- tube manometer. what is the reading on that manometer in inches of water? (b) at one point on the model a pressure of 2058 psf is measured. what is the local airspeed at that point?
