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.
Answer:
a roller coaster at top.on hill
110 grams
mass of salt + mass of water
10 + 100
110g
Earths surface gravity: 9.7
Venus surface gravity: 8.8
Mercury's surface gravity: 3.7
Your answer would be D: Earth, Venus, Mercury
Hope this helps! (:
In this area the convection is taking place inside the water which is inside the utensils.
<u>Explanation:</u>
- Convection is the type of heat transfer method which is usually taking place through the liquid and gases. In this convection process, the liquid acts as the medium for the heat transfer.
- From the given picture we can see both convection and conduction. The conduction process which occurs in the solid objects. Here the heat is directly given to the pan which is a solid conductor so the pan conducts the heat.
- Inside the pan there happens to be the liquid which favors the convection process and again the eggs are heated by the conduction process as the outer part of the egg is solid.
