An automobile starter motor has an equivalent resistance of 0.0510 ω and is supplied by a 12.0 v battery with a 0.0090 ω internal resistance. (a) what is the current (in a) to the motor? a (b) what voltage (in v) is applied to it? v (c) what power (in kw) is supplied to the motor? kw (d) repeat these calculations for when the battery connections are corroded and add 0.0900 ω to the circuit. (significant problems are caused by even small amounts of unwanted resistance in low-voltage, high-current applications.) current a voltage v power kw

Describe the path of the electric current through a circuit?

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
