Q. A cylinder is closed by a piston connected to a spring of steady 2x 10^3 N/m. With the spring relaxed, the cylinder is filled with 5.00 L of gas at a pressure of 1.00 atm and a temperature of 20°C.
a) If the piston has a cross sectional area of 0.0100 m^2 and negligible mass, how high would it rise when the temperature is raised to 250°C?
b) What is the pressure of the gas at 250°C?
After being accelerated to a speed of 1.7×10 5 m/s, the particle enters a uniform magnetic field of strength 1.00 T and travels in a circle of radius 35.0 cm (determined by observing where it hits the screen as shown in the figure). The results of th..
assume a charge starts at rest on an equipotential surface, is moved off that surface, and then is eventually returned to the same surface at rest after a round trip. How much work did it take to do this? Explain.
A stone with a mass of 0.700 is attached to one end of a string 0.8 long. The string will break if its tension exceeds 65.0 . The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed.
For a damped oscillator with a mass of 320g, a spring constant 82N/m and a damping coefficient of 71g/s, what is the ratio of the amplitude of damped oscillations to the initial amplitude at the end of 28 cycles.
What is the magnitude of an object's average velocity if an object moves from a point with coordinates x = 2.54 m, y = -3.56 m to a point with coordinates x = 7.85 m, y = -6.54 m in a time interval of 2.02 s.
A small, 300 g cart is moving at 1.60 m/s on an air track when it collides with a larger, 1.00 kg cart at rest. After the collision, the small cart recoils at 0.890 m/s.

Assume that when you ride on your 7.60-kg bike the weight of you and the bike is supported equally by the two tires. If the gauge pressure in the tires is 78.5 lb/in2 and the area of contact between each tire and the road is 7.13 cm2, what is your we..
A generator uses a coil that has 140 turns and a 0.50-T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. assume that each turn of the coil is a square (an approximation), find out the length of the..
