What is the magnitude of the line charge density on the power line?

A 33 kg gun is standing on a frictionless surface. The gun fires a 57.7g bullet with a muzzle velocity of 325m/s. The positive direction is that of the bullet. Calculate the kinetic energy of thebullet immediately after the gun was fired.

How much farther will a car skid if it locks its brakes at 60 mph as compared to a skid from 15 mph? Assume the braking force that will eventually stop the cars is provided by the road and that it acts with equal magnitude in both situations.

6. I just pulled up to Sheetz and filled my car up with gas. Explain the transfer of energy that would occur once I start then drive my car--consider the type of energy that exists within the gas molecules, explain the transfer of form of energy as

If atmospheric pressure suddenly changes from 1.00 atm to 0.896 atm at 298 k, how much oxygen will be released from 3.30 l of water in an unsealed container?

Calculate the pressure of an enclosed fluid on which a force of 150 N is exerted over an area of 10 cm2. give the answer in pascals.

Two cars are moving in the same direction in parallel lanes along a highway. At some instant, the velocity of car A exceeds the velocity of car B. Does that mean that the acceleration of car A is greater than that of car B? Explain.

A motorist enters a freeway at 45 km/h and accelerates uniformly to 99 km/h. From the odometer in the car, the motorist knows that she traveled 0.2 km while accelerating.

What is the Coriolis Force?

Einstein's general theory of relativity made or allowed us to make predictions about the outcome of several experiments that had not yet been carried out at the time the theory was first published.

What factors that affect friction?
