If a brick is chopped in half, what is the

density of the half of block?for science

Density of half of the block will remain unchanged.

Explanation:

Here, a brick has been given and is stated that brick has been chopped in half. so, what will be the new density of that half block..

Density is been defined as mass per unit volume.

so, even when the brick is cut in half the density remains unchanged.

Density is said to be an intensive material which does not depend upon size, phase, amount of the given material in the given system.

Density has a direct relationship with two properties i.e.

mass and volume.

when one property gets changed other one follows.

so, finally the density doesn't gets changed.  

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

the dependant variable is spilled water

the independent is the heat
