Answer:
144 W
Explanation:
The power absorbed by a resistor is the product of the current passing through it and the voltage drop across it. Hence
Other variations of this formula are derived using Ohm's law, 
is the resistance of the resistor. It is what causes the voltage drop.
Answer:
(a): The cyclist is behind the car.
(b): The speed of the car are Vf= 31.97 m/s.
Explanation:
f= 440 Hz
f'= 415 Hz
Vo= 1/3 Vf
Vf= ?
V= 343.2 m/s
f'= f* ( (V-(-Vo) / (V-(-Vf) )
clearing Vf
:
Vf= 31.97 m/s
Vo= 10.65 m/s
Answer:
