28.5g of iron shot is added to a graduated cylinder contaning 45.50ml of water. the water level rises to the 49.10 ml mark, from this information, caculate the density of iron

7.92 g/ml

Explanation:

Given that, the volume of water  in the graduated cylinder is,

Volume of (water+iron shot) is,

Now the volume of iron shot can be calculate as,

And the mass of the iron shot which is given is 28.5 g.

Now the density can be calculated as,

Here, m is the mass, V is the volume

Now,

Therefore, the density of iron is 7.92 g/ml.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
