A day is added to February every four tears as a corrective measure. The Earth does not exactly revolve around the sun for 365 days. There is a small offset that is corrected by adding a day to February. This happens every four years and it is called Leap year.
<u>Answer:</u> The mass of plastic sheet is 
<u>Explanation:</u>
The plastic sheet is in the form of cuboid. To calculate the volume of cuboid, we use the equation:
where,
V = volume of cuboid
l = length of cuboid = 10.0 m = 1000 cm (Conversion factor: 1 m = 100 cm)
b = breadth of cuboid = 1.0 m = 100 cm
h = height of cuboid = 1 cm
Putting values in above equation, we get:
To calculate mass of a substance, we use the equation:
We are given:
Density of plastic sheet = 
Volume of plastic sheet = 
Putting values in equation 1, we get:
Hence, the mass of plastic sheet is
not until 9/17. it was the longest shutdown since 1933
They're not important when solving math problems in class because you need to get the correct and accurate answers hence don't need to change them into significant figures
Yes. Avogadro Law gives the relationship between volume and amount when pressure and temperature are held constant. Remember amount is measured in moles. This means the gas pressure inside the container will increase (for an instant), becoming greater than the pressure on the outside of the walls.
