A box of mass 16 kg is pulled at a constant velocity with a cord that makes the angle32 degrees as shown in the sketch. If the coefficient of kinetic friction between boxand the surface at which it is sliding on is 0.21, and tension in the string is 13 N,what is the value of kinetic friction force? (Note: Use g = 10 m/s^2 and round answerto two significant figures. Learn about sig. fig. in Section 1.3 of book or fromprovided handout)velocity constant

The electromagnet shown in the Fig. below is to be used to lift an iron slab of mass M=150 kg. The surface roughness of the iron is such that when the iron and the electromagnet are in contact, there is a minimum air gap of 0.2 mm in each leg. The electromagnet has infinite permeability and the crosssectional area Ac is 25 cm2. The number of turns of N-turn winding is 350 and the winding coil resistance is 3 Ω. Calculate the minimum coil voltage which must be used to lift the iron slab against the force of gravity. Neglect the reluctance of the iron.(Hint: Gravitational acceleration constant is 9.8 m/s2)

A wire with negligible resistance is arranged in a magnetic field with a strength of 20 T oriented into the page as shown. A slider with a mass of 250 grams is connected to the fixed wire and can slide without friction. The slider has a resistance of 3 ohms. When the slider is released from rest, it begins to accelerate downward but quickly reaches a constant velocity. a) Determine the magnitude and direction of the current in the slider as it falls at a constant speed. b) Determine the induced emf in the loop as the slider falls at a constant speed. c) Determine the speed at which the slider falls. d) If the resistance of the slider is increased, will the constant speed of the slider be lower, higher, or the same as determined in part c? Justify your answer.
