Problem 18P

A wheel 33 cm in diameter accelerates uniformly from 240 rpm to 360 rpm in 6.5 s. How far will a point on the edge of the wheel have traveled in this time?

Step-by-Step Solution:

Solution:First we want to know about the optical tweezers.Optical tweezers:The optical tweezers is the originally called as single-beam gradient force trap, arescientific instruments that use a highly focused laser beam to provide an attractiverepulsive force.Optical tweezers have been particularly successful in studying a variety of biologicalsystems.In biological we are now going to measure the elasticity of individual DNA molecules.In the above figure shows the DNA molecule through the Optical tweezers.Step 1Hooke’s law:When the spring is stretched or compressed, it exerts a force proportional to the change.Restoring force,\n F = -k x k is the spring constant xin its length but in the opposite direction.
