Answer 1

Answer:

8000 kg m^3 is the answer

Explanation:

This can be found from the mass of the volume of water displaced. And the volume of water is easy to figure since 1 liter is one kilogram.

The difference in weight is the weight of the displaced water, so that amount of water weights 0.06 Newtons. Convert to kilograms,  

1 kilogram has a weight of 9.8 Newtons (N) at the earth’s surface.

So the mass of the water W = 0.066N / (9.8 N / 1 kg) which gives the mass of water.

The mass of the water can be converted to kilograms which will give you the volume of the spoon in liters.

Just convert 0.48 N to kilograms as was done for the water, for volume of spoon.

As you have mass now, convert it into density.
