You intend to move a rectangular loop of wire into a region of uniform mag- netic field at a given speed so as to induce an emf in the loop. the plane of the loop must remain perpendicular to the magnetic field lines. in which orientation should you hold the loop while you move it into the region with the magnetic field to generate the largest emf? select one: 1. (a) with the long dimension of the loop parallel to the velocity vector2. (b) with the short dimension of the loop parallel to the velocity vector3. (c) either way because the emf is the same regardless of orientation

What is the length x of the side of the triangle below? (hint: use the cosine function)

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?

Which best represents the law of conservation of mass ?
