Atrain leaves the station heading west on the tracks . it takes the train 8 seconds to reach 80 miles per hour . it completes the entire 160 mile trip in two hours . calculate the train's average speed and velocity over the two hour trip . show your work . identify if each of the measurements are a scalar or vector quantity.

In science and physics what is the standard unit of measure for speed?

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop

The velocity of a car traveling in a straight line increases from 0 meters/second to 30meters/second in 8 seconds. what is the average acceleration of the car?
