A rocket and driver have a combined mass of 200kg. The rocket has a thrust of 3900 Newtons as it accelerates up an inclined plane that has an angle = 20°. The coefficient of kinetic friction between the rocket and plane is the = 0.3

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. what is the specific heat ratio? show the math steps .

Which of the following are appropriate acceleration units?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
