When using the right-hand rule to determine the direction of the magnetic field around a current-carrying wire, the of the right hand must point in the direction of the current.

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1

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.

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?
