Consider an infinitely thin flat plate of chord c at an angle of attack α in a supersonic flow. the pressures on the upper and lower surfaces are different and linearly varying over each surface; that is, pu(s) = c1 (x/c) and pl(s) = c2 (x/c), where c1 and c2 are constants and c2 > c1. ignoring the shear stress, calculate the location of the center of pressure. (round the final answer to two decimal place.)

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
