A guy walks into a 7-11 store and selects four items to buy. The clerk at the counter informs the gentleman that the total cost of the four items is $7.11. He was completely surprised that the cost was the same as the name of the store. The clerk informed the man that he simply multiplied the cost of each item and arrived @ the total. The customer calmly informed the clerk that the items should be added and not multiplied. The clerk carefully added the items together and informed the customer that the total was still exactly $7.11. (There was no sales tax involved) Determine the exact costs of each item.

There is a clever kitchen gadget for drying lettuce leaves after you wash them. It consists of a cylindrical container mounted so that it can be rotated about its axis by turning a hand crank. The outer wall of the cylinder is perforated with small holes. You put the wet leaves in the container and turn the crank to spin off the water. The radius of the container is 12 cm. When the cylinder is rotating at 2.0 revolutions per second, what is the magnitude of the centripetal acceleration at the outer wall?

a horizontal force of magnitude 35.0N pushes a block of mass 4.0kg across a floor where the coefficient of kinetic friction is 0.600. 1)how much work is done by that applied force on the block - floor system when the block slides through a displacement of 3.00m across the floor? 2)during that displacement, the thermal energy of the block increases by 40.0J. what is the increase in thermal energy of the floor? 3)what is the increase in kinetic energy of the block?

full solution pleas.
