A slide-loving pig slides down a certain 35 degree slide in twice the time it would take to slide down a frictionless 35 degree slide. What is the coefficient of kinetice friction between the pig and the slide? I know that when the coefficent of kinetic fricition is zero t=1/2...

Two infinitely-long lines of charge run parallel to the z axis. One has positive unifonn charge per unit length, IvO, and goes through the x y plane at x=O, y=s/2. The other has negative unifonn charge per unit length, -A, and goes through x=O, y=-s/2. Nothing changes with the...

first you would want to convert feet to miles or vice versa. Then, youll want to build the triangle because you start at 40,000 feet and then that goes at a six degree angle along the x axis for 20 miles. So you will want to put this on a cartesian plane because from there you...

A 500-turn circular coil with an area of 0.050 0 m2 is mounted on a rotating frame that turns at a rate of 20.0 rad/s in the presence of a 0.050 0-T uniform magnetic field that is perpendicular to the axis of rotation. What is the instantaneous emf in the coil at the moment ...

**Calculus**

The direction vector of the given line is (2,-1,3) and a point on it is (0,3,1) So using that point and the additional given point (1,2,-2) yields a second direction vector of (1,-1,-3) So we need a normal to these two direction vectors, which is the cross-product of (2,-1,3) ...

**Geometry**

Concurrent lines are lines that intersect at a single point. Well, a figure cannot be shown here, but try to draw/imagine. For instance, in an x-y plane, you have the three concurrent lines that intersect at the origin. Now, in order to have one pair of parallel lines, the ...

Four identical particles, each with mass m, are arranged in the x,y plane like a cross. They are connected by light sticks to form a rigid body. If m=2.0kg and a=1.0 m the rotational inertia of this array about the y axis is: work: I know that I= mr^2 I=(2.0kg)(1.0m)^2 I=2 kgm...
