When an x-ray photon with wavelength = 0.070nm strikes an electron at rest, it will be scattered at some angle due to the Compton Effect.
a) What is the maximum angle through which it may be scattered?
b) What is the maximum amount by which the photon's wavelength can be changed?
A fighter jet is launched from an aircraft carrier with the aid of its own engines & a steam-powered catapult. The thrust of its engines is 2.3 x 105 N. In being launched from rest it moves through a distance of 87 m & has a kinetic energy of 4.5 ..
Charges q and Q are placed on the x axis at x = 0 and x = 2.0 m, respectively. If q = -40 pC and Q = +30 pC, define the net flux through a spherical surface (radius = 1.0 m) centered on the origin.
Suppose he hits the ball with a speed of 29 m/s at an angle of 26° above the horizontal. Explain how long was the ball in flight? How far did it travel?
Two pencils have the same average density (500 kg/m^3). The mass of the mechanical pencil is twice the mass of the conventional pencil. Which accelerates at the greater rate
A snowboarder is pulled by a tow rope along a horizontal surface with a constant force of 60 N. How far must the boarder be pulled, starting from rest, so that her final kinetic energy is 500 J.
The springs of a 1300kg car compress 6.00 mm when its 68 kg driver gets into the driver's seat. If the car goes over a bump, what would be the frequency of vibrations.
The Balmer series in atomic hydrogen is the series of wavelengths emitted by the electron when it makes a transition from an energy level with n > 2 to the n = 2 level, Find the four largest wavelengths in the Lyman series
A trapeze artist performs an aerial maneuver. While in a tucked position, what is her rotational speed
The Sun is a low mass star and so would never have the core fusion reactions of massive stars. Yet, the Sun has iron in its atmosphere, as well as gold, silver and other elements much heavier than iron and why?
What is the magnitude of an average acceleration of the ball
