During an all-night cram session, a student heats up a 0.668 liter (0.668 x 10- 3 m3) glass (Pyrex) beaker of cold coffee. Initially, the temperature is 16.8 °C, and the beaker is filled to the brim. A short time later when the student returns, the temperature has risen to 93.8 °C. The coefficient of volume expansion of coffee is the same as that of water. How much coffee (in cubic meters) has spilled out of the beaker?
What are (a) the energy, (b) the momentum, and (c) the wavelength of the photon that is emitted when a hydrogen atom undergoes a transition from the state n = 3 to n = 1?
A photon with an initial wavelength of 1.150×10-11 m Compton scatters from an electron which is initially at rest. What is the kinetic energy of the scattered electron
The asteroid belt circles the sun between the orbits of Mars and Jupiter. One asteroid has a period of 4.0 earth years
Starting from one oasis, a camel walks 25 km in a direction of 30 degrees south of west and then walks 30 km toward the north to a second oasis. What is the direction from the first oasis to the second oasis?
Suppose a single electron orbits about a nucleus containing two protons (+2e), as would be the case for a helium atom from which one of the naturally occuring electrons is removed. obtain the magnitude of the electron's centripetal acceleration
Consider a planet of radius 5.78 106 m with a rotation period of 21.6 hours. Compute the radial acceleration of a point on the surface of the planet
An airplane flies eastward and accelerates uniformly. At one position along its path it has a velocity of 33.5 m/s. It then flies a further distance of 46.9 km and its velocity is 43.1 m/s. Find the airplane's acceleration and calculate how much t..
