A long straight cable of radius a = 0.100 m lies along the x-axis. Inside the cable the current density is constant and has magnitude J = 5.00 ( Ampere m-2 ). The current density is directed along the + x direction. Let s be cylindrical radius. i. What is the current running through the cable between radius 0 and s? ii. What is the magnetic field as a function of s inside the cable? iii. What is the total...

A person pulls a small trolley of mass 30 kg along a flat icy road with a rope. The rope exerts a tensile force of F = 300 N and makes an angle θ = 25o with the horizontal. The figure illustrates the situation but is not drawn to scale. Taking the acceleration due to gravity as g = 10 m s-2 in any calculations and round your answers to the nearest integer. You can assume that any frictional forces...

Suppose you have a connected network of two-way streets. Show that you can drive along these streets so that you visit all streets and you drive along each side of every street exactly once. Further, show that you can do this such that, at each intersection, you do not leave by the street you first used to enter that intersection unless you have previously left via all other streets from that intersection

You are driving along straight road. You cover 200 miles in 4 hours? Does that mean that your speedometer read 50 mph for your entire trip? Is is necessary that your speedometer register 50 mph at least once during the trip? Use math to explain your answer. I understand that your speedometer would not be 50mph for the entire trip, but I am not sure how to explain it using math.

Consider driving a car in one direction along a straight road for 10 minutes. You start from rest. During the first 1 minute, you speed up with constant acceleration until you reach 60 m/s. During the next 5 minutes, you maintain constant speed at 60 m/s. During the final 4 minutes, you have constant negative acceleration (i.e. deceleration) until you are not moving. How far in total did you travel during the whole 10 minutes? Express your answer in units...
