The de Broglie relation applies to all "particles," not just electrons and photons.
(a) Calculate the wavelength of a neutron whose kinetic energy is 1 eV.
(b) Estimate the wavelength of a pitched baseball. (Use any reasonable values for the mass and speed.) Explain why you don't see baseballs diffracting around bats.
Air traffic controllers use radar to keep track of the location of aircraft.
A point charge with Q1=2e-7 Coulombs is placed at the point y=-0.05 meters on the negative y-axis and another charge Q2 = 2e-7 Coulombs is placed at the point y=0.05 meters on the positive y-axis. Find the electric field, magnitude and direction, at ..
Illustrate what is the gauge pressure at the upper face of the block? what is the gauge pressure at the lower face of the block? what is the mass of the block?
A horizontal spring with spring constant 140 is compressed 20 and used to launch a 2.6 box across a friction less, horizontal ground. Find How far the box slides across the rough ground before stopping
Calculate the tension in a horizontal strand of spiderweb if the same spider sits motionless in the middle of it much like the tightrope walker in Figure. The strand sags at an angle of 15.0o below the horizontal.
