35.A rod AB of mass M and length L is lying on a horizontal frictionless surface. A particle of mass m travelling along the surface hits the end ‘A’ of the rod with a velocity v 0 in a direction perpen­dicular to AB. The collision is elastic. After the ‘collision the particle comes to rest. (a)Find the ratio m/M .

    The conducting rod shown in the figure has length L and is being pulled along horizontal, frictionless, conducting rails at a constant velocity. The rails are connected at one end with a metal strip. A uniform magnetic field, directed out of the page, fills the region in which the rod moves.

    The object moving up an inclined plane needs to move the entire length of the slope of the plane to move the distance of the height. For example, if you have a ramp with a slope length 20 meters that rises 5 meters high, then your trade-off is moving the 20 meters distance versus lifting straight up 5 meters, and your mechanical advantage is 4.

    There are two commonly used units of measurement for angles. The more familiar unit of The reason that this definition works is that the length of the subtended arc is proportional to the radius of the circle. If the gauge is 5 feet, find the difference in length of the two rails to the nearest half-inch.
