Answer:
It covers distance of 9.15 football fields in the said time.
Explanation:
We know that

Thus distance covered in blinking of eye =

Thus no of football fields=
True because all switches use contacts to start or stop the flow of electrons in a circuit
16 kilometers is the answer i came up with. hope this helps.
Answer:
The current is 0.248 A
Explanation:
Given that,
Inductor 
Resistance 
Voltage = 15 volt
Time 
We need to calculate the current
Using formula of current

Where, V = voltage
R = resistance
L = inductance
T = time
Put the value into the formula


Hence, The current is 0.248 A.
Explanation:
a. Average speed = distance / time
= 100 m / 70 s
= 1.43 m/s
b. Average displacement = displacement / time
= 0 m / 70 s
= 0 m/s
Distance is the length of the path traveled. Displacement is the difference between the final position and initial position.
