The equivalent resistance of the three resistors when connected in parallel is:
Since the three resistors in this problem are identical, we can call R their resistance, and we can rewrite the previous equation as
And since we know the value of the equivalent resistance,
, we can find the value of R:
Now the problem asks us what is the equivalent resistance of the three resistors when they are connected in series. In this case, the equivalent resistance is just the sum of the three resistances, so
Something that goes round in circles could have a high speed but zero average velocity.
Answer:
999.23 km/h
Explanation:
We can use the formula for average speed as "Distance divided time" to solve the problem.
Let's start by writing the time in hours: 4 h and 20 min is the same as 4 hours + 1/3 of an hour = 13/3 of an hour
Now we use this number in the quotient for average speed:
Average speed = 4330 km / (13/3) h = 12990 / 30 km/h = 999.23 km/h
The answer is slightly left and slightly right of the curved end of the horseshoe.
