Answer 2

Given: x is the power of mass and y is the power of time in the dimensions of density

To find: Value of x and y

Explanation: The formula for density is given by mass / volume.

Now, dimensions of mass is: M L^0 T^0

Volume= (Side)^3

Dimensions of side = M^0 L T^0

Therefore, dimensions of volume= M^0 L^3 T^0

Dimensions of density= Dimensions of Mass / Dimensions of volume

= M L^0 T^0 / M^0 L^3 T^0

= M L^-3 T^0

Here, we see that in the dimensional analysis of density the power of mass is 1, time is 0 and length is -3.

Therefore, the value of x is 1 and value of y is 0.
