Why do clothes often cling together after tumbling in a clothes dryer? 1. the dryer heat caused some of the fabrics to melt together. 2. gravitational force 3. air pressure 4. the clothes are electrically neutral. 5. electrical force?

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
