Answer:
30.24m
Explanation:
When adding numbers together, we round to the smallest number of decimal places of the numbers, which is 2 decimal places in this case.
24.686m + 2.343m + 3.21m = 30.23<u>9</u> m
≈ 30.24m (round to 2 d.p.)
When you round numbers to a certain digit (hundredth in this case), you would want to look on the digit on its right (thousandth in this case). If that digit is 1-4, you round the digit down. If that digit is 5-9, you round the digit up. Since the digit in the thousandths place is 9, you round the hundredth digit up from 3 to 4.
Answer:
Total displacement will be 1120 meters.
Explanation:
To calculate displacement from the velocity, need to take integral of velocity for a one time period.
The total displacement is 1120 meter in negative way.
The mutual inductance of the two coils is 1.28*10^-3H.
To find the answer, we have to know about the mutual inductance.
<h3>How to find the
mutual inductance of the two coil?</h3>
- We have the expression for emf in terms of mutual inductance and rate of change of current as,
- From the question, it is clear that,
- Thus, the mutual inductance is,
Thus, we can conclude that, the mutual inductance of the two coils is 1.28*10^-3H.
