Suppose a tank contains 624 m3 of neon (Ne) at an absolute pressure of 1.01 105 Pa. The temperature is changed from 293.2 to 295.5 K. What is the increase in the internal energy of the neon?
What is the new momentum of the puck. What is the length of pipe.
We are not normally aware of the gravitational or electric force between two ordinary objects. What is the reason in each case? Give an example where we are aware of each one and why.
Determine the value of the electric potential. calculate the acceleration of the ball when it is 3 cm from the surface and again at the position determined in part b.
Find out the type of mirror and how far the object is
Nobel laureate Richard Feynman (1918-1988) once said that if two persons stood at arm's length from each other and each person had 1% more electrons than protons, the force of repulsion between them would be enough to lift a "weight" equal to that..
A 2.25×10^4 elevator is to be accelerated upward by connecting it to a counterweight using a light (but strong!) cable passing over a solid uniform disk-shaped pulley. There is no appreciable friction at the axle of the pulley, other than its mass..
How much work is required to stretch the spring. A satellite is in a low circular orbit about the Eart.
The magnitude FN of the normal force that each side of the tread channel exerts on the stone is 1.8 N. Suppose that only static friction supplies the centripetal force, & find the radius r of the tyre.
A small body of mass 0.28 kg is undergoing simple harmonic motion of amplitude 4.0 cm and period 0.10 s. What is the maximum value of the force acting on it? If the oscillations are produced by a spring, what is the spring constant?
A 10000 N car comes to a bridge during a storm and finds the bridge washed out. The 750N driver must get to the other side, What is the speed of the car just before it lands safely on the other side
Assume that an inexpensive watch runs 0.004% slower than a "perfect watch" (viz., a "time standard") that neither loses nor gains time, what would the perfect watch measure for this time interval
A positive charge Q1 = 3.00 µC is in the origin and a negative charge Q2 = -5.00 µC is at point x = 11m. Find the position of point P between the charges, where the electric potential equals zero.
