Answer:
0.031 W
Explanation:
The power used is equal to the rate of work done:
where
P is the power
W is the work done
t is the time taken to do the work W
In this problem, we have:
W = 900 J is the work done by the motor
t = 8 h is the time taken
We have to convert the time into SI units; keeping in mind that
1 hour = 3600 s
We have
And therefore, the power used is
Superconductor, conductor, semiconductor, insulator
In an arithmetic progression, consecutive terms differ by the same value.
So, we have
which reflects the fact that the difference between P and 6 must be the same than the one between P and 14.
The equation solves to
And in fact, if you start with
every pair of consecutive terms differ by 4.
I believe that it is the first one just a guess tho. So don't trust me, just in case
Answer:
accuracy refers to the deviation of a measurement from a standard or true value of the quantity being measured
