A particle of mass 4.47 × 10?27 kg, moving at 9.46 × 105 m/s, strikes an identical particle which is initially at rest. After the interaction, the particles (which can't be distinguished) are observed moving at angles 70.2° and 19.8°, both angles being measured with respect to the original direction of motion. What are the final speeds of the particles?
what is the electric force between the proton and electron inside of a hydrogen atom? What must the speed of the electron be? Radius=0.47 x 10^-9.
A cannonball sits on top of a 10 meter cliff and is fired at a 10 degree angle with an initial velocity of 50 m/s. What is the maximum height of the cannonball relative to the ground? At maximum height what is the magnitude of the velocity? How lo..
A block of mass 2.0 kg is pushed against a vertical wall by a horizontal push (P) of 50.0 N. The block does NOT move. Assuming that the coefficient of the static friction, k, is equal to 0.60. Find the force AND the direction of the friction.
The magnitude of earth's magnetic field is 50.0 µT and makes an angle of 30° with the plane of the coil. Assume a patient takes 1.50 s to inhale, find the magnitude of average induced emf in the coil during that time.
A constant horizontal force a pushes a 4.40kg FedEx package across a frictionless floor on which a xy coordinate system has been drawn. The package's x and y velocity components versus time t.
An infinitely long line of charge has a linear charge density of 5.50×10-12 C/m. A proton is at distance 17.5 cm from the line and is moving directly toward line with speed 2900 m/s.
How far apart would the two sphere. Uranium-238 (U238) has three more neutrons than uranium-235 (U235). Compared to the speed of sound in a bar of U235, is the speed of sound in a bar of U238 higher, lower, or the same? There are several factors ..
A step-up transformer has 26 turns on the primary coil and 770 turns on the secondary coil. what input current and voltage are needed
A butterfly flies from the top of a tree in the center of a garden to rest on top of a red flower at the gardens edge. Determine the magnitude of the butterflys displacement
A flat circle of radius 20 cm is placed in a uniform electric field of magnitude 6.6×102N/C, What is the electric flux through the circle when its face is at 30 to the field lines
For instance, the flute can be described as an open-open pipe because a flutist covers the mouthpiece of flute only partially. Meanwhile, a clarinet can be described as an open-closed pipe as the mouthpiece of the clarinet is almost completely closed..
