A particle has a charge of +1.7 ?C and moves from point A to point B, a distance of 0.12 m. The particle experiences a constant electric force, and its motion is along the line of action of the force. The difference between the particle's electric potential energy at A and B is EPEA - EPEB = +7.7 x 10-4 J. (a) Find the magnitude of the electric force that acts on the particle. (b) Find the magnitude of the electric field that the particle experiences.
Find the resultant forces and moments at wrist, biceps muscle force, elbow and shoulder and joint reaction force using 2-D static analysis.
As an energy-efficiency consultant, you're asked to assess the pumped-storage facility. Its reservoir sits 136 above its generating station and holds 9.0×10^9 of water. The power plant generates 315 of electric power while draining the reservoir over..
What is the least coefficient of friction between tires and road that will allow cars to negotiate the turn without sliding off the road?
A gas bubble with an initial volume of 7.00 milliliters rises from a depth of meters. If the temperature does not change, what is its volume, to nearest ml, when it reaches the surface (density of water=1000 kg/m^3)?
Select True or False for the following statements about conductors in electrostatic equilibrium. The electric field inside the conducting material is always zero.
Suppose the player has a mass of 0.658 kg. How long might the player operate on the energy required to lift it through a height of 1.17 m.

A shopper pushes a cart 50 m south down one aisle and then turns 90° west and moves 28 m. He then makes another 90° turn and moves 11 m.
Helium (He), a monatomic gas, fills a 0.012 m3 container. The pressure of the gas is 6.90x 10^5 Pa. How long would a 0.25 hp engine have to run (1 hp = 746 W) to produce an amount of energy equal to internal energy of this gas.
When you push a 1.95kg book resting on a tabletop it takes 2.50N to start the book sliding. Once it is sliding, though, it takes only 1.50N to keep the book moving with constant speed. What are the coefficients of static and kinetic friction betwe..
Two cars are traveling along a straight road. Car A maintains a constant velocity of 110 km/h and car B maintains a constant speed of 110 km/h. At t= 0, car B is 45 km behind car A. How far would car A travel from t = 0, before it is overtaken by c..
