Which of these is not a resistor?
a. wire
b. light bulb
c. hair dryer
d. all of these are resistors

The correct answer is (d.) all of these are resistors. A resistor creates the reduction of the current flow and voltage levels within the circuits. A wire is a resistor because it is made up of alloy and carbon that helps to maintain a low resistance and have an easy flow of the electric charges. Same as the light bulb and the hair dryer, they all reduce the current flow.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
