Q. A proton collides elastically with a stationary deuteron. If the proton is deflected through 37 degrees, what fraction of its kineti energy does it transfer to the deuteron?
Q. The springs of a 1300 {rm kg} car compress 5.0 {rm mm} when its 66 {rm kg} driver gets into the driver's seat.If the car goes over a bump, what will be the frequency of vibrations?
Calculate the power required by an object to lift another object
A race car has a mass of 702kg. It starts from rest and travels 42 m in 3 s. The car is uniformly accelerated during the entire time. What net force is exerted on it.
Find the position of the object to acquire real, magnified image, inverted, and virtual, upright image.
Suppose that the speed of the water in the reservoir is zero, and that the water flow is steady. Overlook both air resistance and the height difference between the reservoir and the muzzle.
Suppose a uniformly charged (with a linear charge density) wire starts at point 0 and rises vertically along the positive axis to a length. Determine the x-component of the electric field at point. That is, compute near one end of a long wire, in the..
Compute the amplitude and phase at the observation screen
It is said that Galileo discovered a basic principle of the pendulum - that period is independent of the amplitude - by using his pulse to time the period of swinging lamps in the cathedral as they swayed in the breeze. assume that one oscillation..
IP Halley's Comet Halley's Comet, which passes around the Sun every 78 years, has an elliptical orbit. When closest to the Sun (perihelion) it is at a distance of 8.823 x 10^10 m and moves with a speed of 54.6 km/s. The greatest distance between Hall..
A 40-kg girl is bouncing on a trampoline. During a certain interval after leaving the surface of the trampoline, kinetic energy decreases to 240J from 470J. How high does she rise during this interval? Avoid air resistance.
What is the propotion of the mass of these excess electrons to the mass of the penny.
How fast must the car be travelling just as it leaves the cliff in order to clear the river and land safely on the opposite side.
What is the size of the smallest vertical plane mirror in which a 10 tall giraffe standing erect can see her full-length image? (Hint: Locate the image by drawing a number of rays from giraffe's body that reflect off the mirror and go to her eye.
