Please... I need this asap! :) Also, I only need couple of lines answer to the short answer question. Thank you again!

Question 10 5.5 pts A car is carrying a piece of plywood with dimensions 2.40 m by 1.15 m. If the mass of the plywood is 12.0 kg, what maximum speed can the car travel before the wood ies off? This is the speed of the air rushing above the plywood as the car moves along. (Density of the air is 1.29 kg/m3) Question 14 5.5 pts A "x" gram ice cube at -5.0 C is dropped into "Y" grams of water at 18.0 C. Find the equilibrium temperature. Choose a mass for the ice cube (X) between 30 and 60 grams and a mass for the water (Y) between 300 and 600 grams, Cice = 2100 J/kg C, Cwater = 4186 J/kg C, Lice = 3.33 x 105 J/kgQuestion 16 5.5 pts 5.0 moles of an ideal gas expands isobarically as shown in the P process A->B. PA = PB = 300.0 kPa, VB = 60.00 L, VA = 35.00 L. VA VB
