A vehicle start moving at 15m/s. How long will it take to stop at a distance of 15m?​

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.

The electric field inside a battery generates an electric potential difference of 12v. the plates are seperated by a distance of 0.25m. what strength of the electric field?
