Explanation:
She stopped for 4 minutes
She was decreasing in speed
Answer:
Tom
Explanation:
Simply because we see Claudia used a shortcut. Tom uses more physical force than Claudia, since Claudia only had to push the boxes into there required shelves.
Concrete is formed of sand. Is it incorrect to suggest that some houses are built using concrete blocks?
Basically this question is telling you to convert units of distance and units of volume. The SI unit of measurement for distance is meters, while the SI unit for volume is liters. In order to go through the conversion, you have to know the equivalence of miles to meters, and gallons to liters. One gallon is equal to 3.785 liters, and one mile is equal to 1609.34 meters. Consequently, in the metric system, 1,000 meters is equal to 1 kilometer.
We make use of these conversions through dimensional analysis. This approach is when you cancel out like units if they appear both on the numerator and the denominator side. The solution is as follows:
14 km/L * (1000 m/1 km) * (1 mile/1609.34 m) * (3.785 L/1 gal)
Cancel out kilometers, meters, and liters. The final answer is in kilometers per liter. The complete solution, is therefore, 0.0329 miles/gal.
Answer is 14.5 g L⁻¹.
<em>Explanation;</em>
Here, the question says reduce the units as one.
The presented units are g/L. To reduce the units to one, what we can do is take L to the upper side.
This can be done according to the rules of indices;
1 / aˣ = a⁻ˣ
Like that, we can write 1 / L as L⁻¹.
Hence, the reduced unit is g L⁻¹.
But remember to keep a space between when writing two different units.
Actually, this is an unit for density.
