2 0-3 points ShippS14 9.E.012 Estimate your de Broglie wavelength fast you can run in meters...
What is the de Broglie wavelength (in meters) of a neutron traveling at a speed of 0.92 c? Since the neutron's speed is close to the speed of light (c), Special Relativity must be used when calculating the linear momentum (p). The mass of the neutron is 1.675 x 10-27 kg. Suppose that an alpha particle (mαα = 6.646 x 10-27 kg) has a kinetic energy of 75 keV. What is the alpha particle's speed (v) (in terms of "c")?...
Part A m, how fast is the The mass of an electron is 9.11 x 10-5 kg. If the de Broglie wavelength for an electron in a hydrogen atom is 3.31 x 10- electron moving relative to the speed of light? The speed of light is 3.00 x 10 m/s Express your answer numerically as a percent. View Available Hint(s)
You are trying to figure out how fast your BB gun can shoot. So you set up a block-spring system. By firing the BB into the block, the spring gets compressed. Specifics: Mass of BB = 8 grams, mass of block = 4.0 kg, spring compression = 3.7 cm, spring constant = 2500 N/m. Calculate the speed of the BB. 1 440 m/s 2 520 m/s 3 500 m/s 4 460 m/s 5 480 m/s Question 14 -- /5 What...

The Joule () is the SI unit of energy. (J = kg:m? S2 A calorie is another unit of energy. The definition of a calorie is the amount of heat (energy) necessary to raise the temperature of Ig of water by 1° Celsius. Ig of water occupies 1 milliliter (ml) = 1 cubic centimeter (cm) of volume. lkcal=4186J Energy comes in many forms and energy may be converted...
