Question1
You're CEO of a courier company, and you decide to select an electric car for your fleet of vehicles. A particular car has a mass of 1500kg and is powered by 26 12−V batteries connected in series, for a total of 312 V. Batteries are rated at 100 ampere-hours, that means they can deliver 100 A for 1 h, 1 A for 100 h, or any combination that equals 100A⋅h. When the batteries are connected in series, the charge output of all the batteries is similar as one battery-in this case 100A⋅h. The motor is 85 percent capable in converting electrical energy to mechanical energy in drive wheels. A test report says car can climb a 15° slope at a speed of 40km/h
Question2
A 4.8 m length of wire is coiled into a solenoid. Thee turns of solenoid are 1.1 cm in diameter. How long is solenoid when it is completely coiled? How many turns are there, assuming an integer number of turns? What is inductance of the solenoid?
