Consider on an inclined air track, the inclined angle is 2 degrees. If in our experiment, the time it takes for the glider to pass the first and second photogate is 0.2s and 0.1s, the length of the glider is 0.1m, try to find the distance d between the two photogates
A loudspeaker is placed between two observers who are 120 m apart, along line connecting them. If one observer records a sound level of 52.8 dB and the other records a sound level of 83.5 dB, how far is the speaker from each observer? Enter the longe..
A string is wrapped around the disk of mass m = 1.8 kg and radius R = 0.11 m. Starting from rest, you pull the string with a constant force F = 8 N along the nearly frictionless surface. At an instant when the center of the disk has moved a distan..
Identical point charges of +3.6 C are fixed to diagonally opposite corners of a square. A third charge is then fixed at the center of the square, such that it causes the potentials at the empty corners to change signs without changing magnitudes.
A point charge of -12 micro-coulombs is fired directly towards a single infinite sheet of charge. It is initially moving at 3.4 m/s towards the sheet and after it has traveled 0.7 meters it is moving at 18.4 m/s.
On a cool morning, when the temperature is 16 deg Celsius, you measure the pressure in your car tires to be 20.0 psi. After driving 40 mi on the freeway, temperature of your tires is 56.0 deg Celsius. What pressure will your tire gauge now show.
A 300 turn solenoid has a radius of 1.00 cm and a length of 15.0 cm. Find the inductance of the solenoid
A 1460-kg submarine rises straight up towards the surface. Seawater exerts both an upward buoyant force of 16300 N on the submarine, as well as a downward resistive force of 1090 N. What is the submarine's acceleration?
Let the x axis be parallel to the ground, +y direction be vertically upward, and take as an origin the point on the ground directly below the top of the ramp.
find out the speed of the test charge. How many electrons should be removed from A and put onto B to make the electrostatic force that acts on each object an attractive force whose magnitude is 23.6 N.
A barbell spins around a pivot at its center at A. The barbell consists of two small balls, each with mass 400 grams (0.4 kg), at ends of a very low mass rod of length d = .6 m. The barbell spins clockwise with angular speed 20 radians/s.
A satellite moves in a circular orbit around the Earth at a speed of 4420 m/s. Determine the period of the satellite's orbit
When one person shouts at a football game, the sound intensity level at the center of the field is 62.4 dB. When all the people shout together, how many people are at the game
