Air is streaming past a horizontal air plane wing such that its speed is over the upper surface and at the lower surface. If the density of air is , what will be the gross life on the wing? If the wing is long and has an average width of 2 m,
We will have general discussion of all physics doubts here.
A small iron sphere is dropped from a great height. It attains its terminal velocity after having fallen 32 m. Then, it covers the rest of the path with terminal velocity only. The work done by air friction during the first 32 m of fall is . The work done by air friction during the subsequent 32 m fall is. Then
A liquid does not wet the sides of a solid, if the angle of contact Select one:
The liquid which do not wet the solid have obtuse angle of contact. For mercury and glass, the angle of contact is .
Please resolve my query.
So how does charge move
