A sheet of aluminum foil has a total area of 1.000 m2 and a mass of 3.636 g. What is the thickness of the sheet in millimeters? Density of aluminum = 2.699 g/cm3. Give your answer with the correct number of significant figures and express the answer in scientific notation.

Explanation:

Given that,

Area of sheet of Aluminium foil is 1 m²

Mass of the sheet = 3.636 g

The density of Aluminium,

We need to find the thickness of the sheet in millimeters.

The density of an object is given in terms of its mass and volume as follows :

V = volume, V = A×t, t = thickness of the sheet

So,

Since, 1 cm = 10 mm

So,

t = 0.00134 mm

or

there is none because earth is stationary and flat.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
