When hiking at altitude, the air pressure drops to 825,000Pa. Solve the force that site exerts against the side of a rectangular tent wall having dimensions of 2.00m long and 0.750m wife.

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?

What part of the ear is names after tools, such as the hammer and the anvil?
