The driver of a 1740 kg car traveling on a horizontal road at 100 km/h suddenly applies the brakes. Due to a slippery pavement, the friction of the road on the tires of the car, which is what slows down the car, is 22.0 % of the weight of the car.
A. What is the acceleration of the Car?
B. How many meters does it travel before stopping under these conditions?
A pendulum of length 3.53 m with a bob of mass 5.50 kg is pulled aside until the bob makes an angle of 35.0° with the vertical. Find the speed of the bob as it passes through the lowest point in its swing
A silver wire has resistivety p = 1.62x10^-8 ?m ana cross sectional area of 5.00 mm^2. what is the displacement current in the wire
A 500 turn solenoid with a length of 20 cmand a radius of 2.0 cm carries a currentof 2.0 A. A second coil of four turns iswrapped tightly about this solenoid so that it can be considered tohave the same radius as the solenoid.
As a new electrical technician, you are designing a large solenoid to produce a uniform 0.250Tmagnetic field near its center. What current will you need to produce the necessary field
