You drop a stone into a deep well and hear it hit the bottom 1.60 s later. This is the time it takes for the stone to fall to the bottom of the well, plus the time it takes for the sound of the sto
0.46mol of argon gas is admitted to an evacuated 30cm^3 container at 60C. The gas then undergoes an isochoric heating to a temperature of 500C. What is the final pressure of the gas?
31g of copper pellets are removed from 300C oven and immediately dropped into 100mL of water at a 25C in an insulated cup. what will the new water temperature be?
A certain elevator cab has a total run of 190 m and a maximum speed of 305 m/min, and it accelerates from rest and then back to rest at 1.22 m/s2. How long does it take to make the nonstop 190 m ru
You are on an airplane traveling 30° south of due west at 150.0 m/s with respect to the air. The air is moving with a speed 38.0 m/s with respect to the ground due north. What is the heading of
If the kinetic energy of the swirling air in the eye could be converted completely to gravitational potential energy, how high would the air go?
A 60 g piece of ice at an initial temperature that is unknown is placed into a glass of 250 g of water sitting at room temperature when it is 80ºF in the room. The glass and ice come to therma
What is the maximum equivalent capacitance that can be obtained by combination of three capacitors of 1.5 µF, 2.1 µF, and 3.3 µF? What is the minimum equivalent capacitance that c
If the radius of the equipotential surface of point charge is 13.5 m at a potential of 2.10 kV, what is the magnitude of the point charge creating the potential?
Current state-of-the-art capacitors are capable of storing many times the energy of older ones. Such a capacitor, with a capacitance of 2.4 F, is able to light a small 0.30 W bulb at full power for
It takes +4.0 J of work to move two charges from a large distance apart to 3.0 cm from one another. The charges have the same magnitude. How large is each charge? And what can you tell about their
It climbs a frictional incline of height 3 m inclined at an angle 12, then moves along a second frictional surface of coefficient 0.19 before coming to rest. The acceleration of gravity is 9.8 m/s2
Whenever the velocity changes, there is a non-zero acceleration. The change can be in only the magnitude of the velocity, in only the direction of the velocity, or in both the magnitude and the dir
A large asteroid of mass 77100 kg is at rest far away from any planets or stars. A much smaller asteroid, of mass 610 kg, is in a circular orbit about the first at a distance of 311 meters as a resu
Two new particles, which have identical positive charge q3, are placed the same 8.09 centimeters apart, and the force between them is measured to be the same as that between the original particles.
Assume that none of the alpha particles bounced back from the sheet, meaning that the alpha particles either were captured by the shielding or penetrated completely through the shielding. What perce
For a particular collision you detect the emitted products and find 17 protons, 4 antiprotons, 8 positrons, and 28 neutral particles. How many electrons are also emitted?
By what distance has the proton been deflected sideways when it reaches the far edge of the capacitor? Assume the field is uniform inside the capacitor and zero outside the capacitor.
A uniform electric field of magnitude 256 V/m is directed in the negative y direction. A +12.9 uC charge moves from the origin to the point (x, y) = (20.0cm, 45.6 cm). What was the change in the pot
An electron starts from rest 2.84 cm from the center of a uniformly charged sphere of radius 2.19 cm. If the sphere carries a total charge of 1.18E-9 C, how fast will the electron be moving when it
To maintain an inside temperature of 21.9°C if the outside temperature is 0.0°C? Disregard radiation and the energy lost by heat through the ground.
Question: A single isolated conductor can store charge. We can define its capacitance as the ratio of the charge to the potential at the surface. (Alternatively, one can think of a second conductor
Three charges are placed on the y axis. One charge of -2.4 micro-Coulombs is placed at y = 0, another charge of +1.7 micro-Coulombs is placed at y = -0.2 meters, and another unknown charge is placed
How much charge, in micro-coulombs, was exchanged? Use the absolute value of the charge exchanged so the answer is positive.
