Which of these is true about the magnetic field of a bar magnet? it has a magnitude at each point but no specific direction. its direction at each location is the same direction it would tend to make a compass point. its direction at each location is the same direction it would tend to make a small test magnet move. its direction at each location is the same direction it would tend to make a small electric charge move.

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?

Which statement correctly describes the relationship between frequency and wavelength?

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c
