To write quantities in ordinary notation, you need to notice the power of the exponent.
If the power is positive, then you move the decimal point to the right by the number the power in exponent tells you.
If the power is negative, then you move the decimal point to the left by the number the power in exponent tells you.
We have:
3 x 10^-4 : the power of exponent is negative, therefore, we will move the decimal point 4 places to the left.
3 x 10^-4 = 0.0003 km
3 x 10^4 : he power of exponent is positive, therefore, we will move the decimal point 4 places to the right.
3 x 10^4 = 30000 km
Displaced volume:
final volume - initial volume
1 mL = 1 cm³
38.5 mL - 35.0 mL = 3.5 cm³
hope this helps!
Answer:
lack of snow in the mountains makes drought cycles worse because mountains are a natural part of the water cycle.
Explanation:
Mountains play a critical part In the water cycle by capturing moisture in the air and it precipitates as snow and when it does this the snow will melt in the warmer seasons and flow down stream then following the rest of the water cycle if we didn't have this then the streams would run less and it would greatly disrupt the water cycle.
Answer:
A mushroom is a heterotroph.
Explanation:
Mushrooms are fungi, which are heterotrophs because they depend on other organisms for their food.
B. carbon-13 is not an allotrope of Carbon.
Allotropes<span> are elements on the periodic table that have more than one crystalline form. </span>Isotopes<span> are atoms of the same element with the same atomic number but have a different mass number.
C-13 is an isotope of carbon, not an allotrope.</span>
