1. An 800 kg car travels around the edge of a circular track of radius 400 m. At one point, the car accelerates around the track, increasing its speed from 40 m/s to 60 m/s over the course of 5 s. At the instant that the car reaches 50 m/s find (a) its angular velocity (b) its radial acceleration, (c)...

Magnetic surveying is one technique used by archaeologists to determine anomalies arising from variations in magnetic susceptibility. Unusual changes in magnetic susceptibility might (or might not) indicate an important archaeological discovery. Let x be a random variable that represents a magnetic susceptibility (MS) reading for a randomly chosen site at an archaeological research location. A random sample of 120 sites...

(10%) Problem 9: Slick Willy is in traffic court (again) contesting a $50.00 ticket for speeding. The speed limit was vo 50 mph and the police officer clocked Slick going vsw 68 mph. However, he was caught by a police officer driving towards him, so he is arguing that although the police officer measured him to be speeding, in reality...

Please include the equation used and how you got the answer.
Four point charges are arranged in a square with side length 2a, where a = 2.7 cm. Three of the charges have magnitude 1.5 nC, and one of them has magnitude - 1.5 nC, as shown in the figure. What is the value of the electric potential generated by...
