1.a block accelerates at 3.1 m/s2 down a plane inclined at an angle 24.0◦. find μk between the block and the in- clined plane. the acceleration of gravity is 9.81 m/s2 . 2.a 1200 kg car moves along a horizontal road at speed v0 = 20.1 m/s. the road is wet, so the static friction coefficient between the tires and the road is only μs = 0.189 and the kinetic friction coefficient is even lower, μk = 0.1323. the acceleration of gravity is 9.8 m/s2 . what is the shortest possible stopping dis- tance for the car under such conditions? use g = 9.8 m/s2 and neglect the reaction time of the driver. answer in units of m. you for the !

Currents in dc transmission lines can be 100 a or higher. some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. for a line that has current 150 a and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? express your answer in teslas and as a percentage of the earth’s magnetic field, which is 0.50 g. is this value cause for worry?

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
