"A 5.0-kg ball rolls without sliding from rest down an inclined plane. A 4.0-kg block, mounted on roller bearings totaling 100g, rolls from rest down the same plane. At the bottom, the block has: "
"A. greater speed than the ball B. less speed than the ball C. the same speed as the ball D. greater or less speed than the ball,depending on the a...
"Two uniform cylinders have different masses and different rotational inertias. They simultane-ously start from rest at the top of an inclined plane and roll without sliding down the plane. The cylinder that gets to the bottomfirst is: "
"A. the one with the larger mass B. the one with the smaller mass C. the one with the larger rotational inertia D. the one with the smaller rotatio...
"When we apply the energy conservation principle to a cylinder rolling down an incline without sliding, we exclude the work done by friction because: "
"A. there is no friction present B. the angular velocity of the center of mass about the point of contact is zero C. the coefficient of kinetic fric...
"Two identical disks, with rotational inertiaI(=1/2 MR2), roll without sliding across a horizontal floor with the same speed and then up inclines. Disk A rolls up its incline without sliding. On the other hand, disk B rolls up a frictionless incline. Otherwise the inclines are identical. Disk A reaches a height 12cm above thefloor before rolling down again. Disk B reaches a height above thefloor of: "
"A. 24cm B. 18cm C. 12cm D. 8cm E. 6cm"
Dipole-dipole forces are attractive forces between positive end of a single polar molecule and also the negative end of another polar molecule. Dipol...
