Bisphenol A (BPA) is a chemical used to make polycarbonate plastics. Polycarbonate plastics are used in
certain food and drink packaging such as baby bottles, water bottles, and other drink containers. People
are exposed to BPA when they drink from these containers because the BPA migrates from the container
into the beverage. Studies have shown that the ingested BPA may affect the brain, behavior, and
reproductive development in fetuses, infants, and children

(hint: you only need two of the 3 numbers given! ) power = work / time 249 watts 25 watts 2075 watts 27.7 watts

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
