Two stationary positive point charges, charge 1 of magnitude 3.25 nC and charge 2 of magnitude 1.9nC, are separated by the distance of 60 cm. An electron is released from rest at the point midway between the two charges, and it moves along the lin..
Four identical point charges (+3.17nC) are placed at the corners of a rectangle, what is the potential at the geometric center of this rectangle
A free floating piston cylinder device that contains 1 kg of a 25% quality saturated mixture of water at 150C, Determine the initial and final pressure, the total energy of electrical work added to the water
The potential difference between the plates of a capacitor is 145 V. Midway between the plates; a proton and an electron are released. The electron is released from rest.
A 25 kg cannon shell is subjected to a constant acceleration of 1200 g while in the cannon barrel. What force is the burning propellant exerting on the shell?
An object is placed 64.5 cm from a screen. Find the magnification of the lens
Once the station is completed, it is set rotating at a rate that requires an object at the rim to have radial acceleration, thereby simulating Earth's surface gravity. This is accomplished using two small rockets, each with 130 thrust that are mounte..
An ocean liner leaves New York City and travels 18.0° north of east for 232 km. How far east and how far north has it gone? In other words, what are the magnitudes of components of the ship's displacement vector in the following directions.
The barrel has a length of 0.60 m and an opening whose radius is 2.8 10-3 m. A bullet (mass = 2.7 10-3 kg) has a speed of 380 m/s after passing through this barrel. Ignore friction and examine the average pressure of the expanding gas.
