Because we are moving with it at the same speed but because that isn’t an answer choice it is probably C
Density is mass divided by volume. The mass of the block is 10 grams. The volume of the block is 2 mL: the water changes from the 3 mL line to the 5 mL when the block is added, so the block must be 5-3= 2 mL.
So, the density is 10 g / 2 mL = 5 g/mL.
Hope this helps!

A cubit is an ancient measurement that measures length
the problem with using cubits is that the size may vary so it isn’t precise
the benefits of standardizing measurement is that they are precise and do not vary unlike the cubits
Answer :
Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell. The calcium carbonate shell gets dissolve.
Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.
When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.
Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.
