Acar radio draws 0.27 a of current in the autos 12-v electrical system. (a) how much electric power does the radio use?
(b) what is the effective resistance of the radio?

(a) 3.24 w (b) 44.44 ohm

Explanation:

It is given that car draws 0.27 A current so current I = 0.27 A

The system has a voltage of 12 V

(a) Electrical power = voltage ×current

(b) The resistance is defined as the ratio of voltage and current

So resistance

0.19 m/s and 0.45 m/s

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
