Draw | IA | a | Ask Copilot Class Work + 33 of 34 D Question 1 The engine of a 3500-N car is generating a constant power of 50 hp (horsepower) while the car is traveling up the slope with a constant speed. If the engine is operating with an efficiency of € 0.8, determine the speed of the car. Neglect drag and rolling resistance. Use g 9.81 m/s² and 1 hp = 745.7 W. 10 го Question 2 A man pushes on a 60-N crate with a force F. The force is always directed downward at an angle of 30° from the horizontal, as shown in the figure. The magnitude of the force is gradually increased until the crate begins to slide. Determine the crate's initial acceleration once it starts to move. Assume the coefficient of static friction is μ = 0.6, the coefficient of kinetic…

state is Derive an expression for the volume expansivity of a substance whose equation of RT P = v-b a v(v + b)TZ where a and b are empirical constants.

For a gas whose equation of state is P(v-b)=RT, the specified heat difference Cp-Cv is equal to which of the following (show all work): (a) R (b) R-b (c) R+b (d) 0 (e) R(1+v/b)
