Athread is being pulled off a spool at the rate of 57.3 cm per sec. find the radius of the spool if it makes 141 revolutions per min. round to two decimal places as needed.

Which statement is true about an object that is moving in a circular motion due to centripetal force, f, when the radius of its circular motion is doubled? the new force then becomes equal to 2f the new force then becomes equal to f the new force then becomes equal to f/2 the new force then becomes equal to f2 the new force then becomes equal to 1/f
