2. A circuit contains, in series, a generator
(4.5 V; 1.5 2) and two resistors R1 = 25
12 and R2 = 18.5 12. Calculate the
current in the circuit by:
a. Applying the law of uniqueness of the
voltage between the terminals of the
generator

According to social exchange theory, altruistic behaviors benefit the individual who performs them.

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?

The speed of light can be used to measure the
