Answer:
O speed of the object increases 9.8 m/s during each second
a = 9.8 m/s/s
That change would most likely cause the current at every point in the circuit
to decrease by 83-1/3% ( 5/6 ) of its original value. Also, the voltage across
each component of the circuit ... resistor, light bulb, motor, open switch etc. ...
would become 5/6 less.
Answer:
Will double
Explanation:
The total resistance of a circuit with n resistors in series is equal to the sum of the individual resistances:
In this problem, we have a circuit with initially one light bulb of resistance R, so the total resistance of the circuit is:
Later, a second identical bulb (so, same resistance R) is added in series to the circuit; so applying the previous formula, we see that the new total resistance is
So, the resistance has doubled.
Hey there!
To solve this question, lets convert 108 km/h into meters per second.
1 km/h is equal to 0.277778 m/s
To convert 108 km/h into m/s, we just multiply 0.277778 by 108.
0.277778 × 108 = 30.000024
So, the train is travelling at approximately 30 meters per second.
Thank you!
