Point charges q1=+2.00?C and q2=?2.00?C are placed at adjacent corners of a square for which the length of each side is 4.50cm. Point a is at the center of the square, and point b is at the empty corner closest to q2. Take the electric potential to be zero at a distance far from both charges.
What is the electric potential at point b?
A point charge q3 = -5.00?C moves from point a to point b. How much work is done on q3 by the electric forces exerted by q1 and q2?
A spherical object with a radius of 40.0 cm has a net charge of 37.7uC distributed uniformly throughout its volume, Using Gauss's Law, calculate the electric field 71.5 cm from the center of the sphere
Explain why? Because when you go to the grocery store they do not take any recognition as a form of payment!" do you agree or disagree? Examine.
Steel Piano string, The lowest note on a grand piano has a frequency of 27.5 Hz. The string is 2 m (more or less; let's just assume it is exactly 2.000 m) long, and its tension is 1000 N (again, more or less, so let's say it's exactly 1000 N).
A galvanometer whose full scale current is 150amps and coal resistance is 75ohms is used with a 1.50 ohms shunt resistor to make an ammeter. what is the largest current that can be measured by the ammeter.
A helicopter is ascending vertically with a speed of 5.00m/s . At a height of 120m above the Earth, a package is dropped from a window. Evaluate how much time does it take for the package to reach the ground?

Important information about Initial kinetic energy of the object Point A is situated at the bottom of a rough plane which is inclined at 45 degrees to the horizontal. A body of mass 0.5 kg is projected from A along and up the line of greatest slop..
At t=0 a grinding wheel has an angular velocity of 20.0 rad/s. It has the constant angular acceleration of 29.0 rad/s^2 until a circuit breaker trips at time t = 2.20 s. From then on, it turns through an angle 435 rad as it coasts to a stop at cons..
An 8.m, 220 N uniform ladder rests against a smooth wall. The coefficient of static friction between the ladder and the ground is 0.75, and the ladder makes a 50° angle with the ground. How far up the ladder can an 770 N person climb before the la..
