The actual answer is 165 miles, but using significant figure rules the answer is 200. This is because the sig fig rules are as follows ...
<span>1. Non-zero digits are always significant.
2. Any zeros between two significant digits are significant.
<span>3. A final zero or trailing zeros in the decimal portion ONLY are significant.
</span></span>
So the zeroes in a number like 20 or 23,000 are NOT significant. When you add numbers you must find the addend with the lowest amount of significant figures and round the answer to that. In this case most of the addends only have one sig fig, so you round 165 to 200 to make it only have one sig fig.
F = ma
100 N= m . 5 ms⁻¹
100 / 5 = m
20 N ms = mass of object.
Answer:
there are over 100 billion stars in our galaxy.
A is false because light and sound waves can both reflect off of objects
Answer:
The value of the inductance is 175.9 mH.
Explanation:
Given that,
Capacitor 
Frequency = 60.0 Hz
The inductor and capacitor is connected in parallel, the voltage across each of these elements is the same.
We have,
Using ohm's law
Put the value into the formula
Hence, The value of the inductance is 175.9 mH.
