In 1919, Rutherford was able to show a breakdown in hisscattering formula for 7.7 MeV, Estimate the radius of the aluminum nucleus
2.0 moles of monatomic gas at atmospheric pressure has a total energy of 7480 J. what is the volume occupied a rigid cylinder by the gas
One of the effects of significant global warming would be the melting of part or all of the polar ice caps. This, in turn, would change the length of the day (the period of Earth's rotation). Explain why. Would the day get longer or shorter?

A 16.8 kg block is dragged over a rough, horizontal surface by a constant force of 123 N acting at an angle of angle 34.9 above the horizontal. Find the magnitude of the work done by the force of friction
Released from rest at the same height, a thin spherical shell and solid sphere of the same mass m and radius R roll without slipping down an incline through the same vertical drop H. Each is moving horizontally as it leaves the ramp.
A 6.0-V battery is connceted in series with a 29-mH inductor, a 110-Ω resistor, and an open switch. After the switch is closed, how much time will elapse before the current in the circuit will be equal to 12 mA?
The position of a particle moving along the x axis is given by x = (32 + 40t - 8.0t2) m, where t is in s. What is the average velocity during the time interval t = 1.0 s to 3.0 s?
