The wind-chill index is modeled by the function w = 13.12 + 0.6215t â’ 11.37v0.16 + 0.3965tv0.16 where t is the temperature (â°c) and v is the wind speed (km/h). when t = â’19â°c and v = 25 km/h, by how much would you expect the apparent temperature w to drop if the actual temperature decreases by 1â°c? (round your answers to two decimal places

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

Standing side by side ,you and a friend step off a bridge at different times and fall for 1.6s to the water below.your friend goes first,and you follow after he has dropped a distance of 2.0m.when your friend hits the water,is the seperation between the two of you 2.0m or more than 2.0m? verify your answer with a calculation.
