Amoving sidewalk in an airport terminal moves at 1 m/s and is 35 m long. if a person steps on at one end of the sidewalk and walks at 1.5 m/s relative to the moving sidewalk, how much time does it take the person to reach the other end of the sidewalk if a) the person walks in the same direction the sidewalk is moving b) the person walks in the opposite direction the sidewalk is moving?

What should the power status of a circuit be when measuring resistance with an ohmmeter?

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
