A lamp draws 0.50 A from a 120-V generator.
1. How much power is delivered?
2. How much energy does the lamp convert in 5.0 min?
An experiment you're designing needs a gas with = 1.60. You recall from your physics class that no individual gas has this value, but it occurs to you that you could produce a gas with = 1.60 by mixing together a monatomic gas and a diatomic gas.
A 2.0 kg mass and a 3.0 kg mass are attached to a lightweight frictionless pulley. The masses are free to move. Find the acceleration of the smaller mass
Two small stereo speakers are 2.8 m apart and act as a double-slit interference experiment with sound waves. If the opposite wall of the room is 7.5 m away and the sound frequency is 1.4 kHz, what is the distance among the two interference maxima nea..
A 0.42 kg ball is dropped from rest at a point 1.30m above the floor. The ball rebounds straight upward to a height of 0.580 m. What are the magnitude and direction of impulse of the net force applied to the ball during the collision with the floo..
A ball is dropped from the top of a building. In the absence of air resistance, the ball will hit the ground with a speed of 49 m/s. The height of the building is
a pingpong ball weighs 0.025 n. the ball is placed inside a cup that sits on top of a vertical spring.the spring is
Calculate the direction of the average force on the ball during the contact . The magnitude of the average force is 4700N
A slug bug hits a semi truck. Both are going the same, constant speed. What one has the higher acceleration? What one has the most force?
A red laser pointer with a wavelength of 635 nm is shined on a double slit producing a diffraction pattern on a screen that is 1.75 m behind the double slit. The central maximum of the diffraction pattern has a width of 4.30 cm, and the fourth bright..
Two balls with a net charge of - 4.0 C and + 10.0 C are separated by 2 cm. A) What is the electrostatic force on the positive charge? B) What is the electrostatic force on the negative charge?
Write the Hamiltonian function and find Hamilton's canonical equations for the three dimensional motion of a projectile in a uniform gravitation field with no air resistance. Show that these equations lead to the same equation of motion as found in S..
