A car moves in a straight line at a speed of 72.1 km/h. How far (in km) will the car move in 7.74 minutes at this speed?

Hey.. ♥️♥️ me in solving this question

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?

Is a volume of space that is empty of matter.
