Two very long straight wires 23.0 cm apart carry equal currents I in the opposite directions. What is then the current I, if the force per unit length between them 2.3 nano N/m. Please input your current answer in mA with one decimal place. (Note 1 nano

Describe uniform velocity and variable velocity in short

Polly is pushing a box across the floor with a force of 30 n. the force of gravity is –8 n, and the normal force is 8 n. which value could describe the force of friction if polly could not move the box?

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?
