You are given the mass of the metal block, but you must calculate its volume using the measurements of the given dimensions. For a rectangular solid, volume = length x width x height; therefore, the volume of the block is (3 cm)(5 cm)(4 cm) or 60 cubic centimeters. The density is 14 g/60 cc or 0.23 g/cc.

First find the volume. The expression for regular shape like cubic solid is v=length x width x height
Then find the mass of the cube by using a scale. Finally use the expression to find the density.
D= mass divided by volume (D= mass/volume )

In dolphins, to have spots on the skin is a recessive trait. One spotted dolphin and one solid gray dolphin have a baby spotted
Kisachek [45]

Answer:

the spotted parent has the genotype ss

Explanation:

we will use s as the letter when describing the spotted trait.

since spotted is recessive, that parents have to have two little s to have the trait. Since the child also has that, we know that they will have the genotype ss.  the child would have to get a little s from both parents, so the solid parent would have Ss, showing as solid, but still having the gene for spots.

The volume of a gas is directly proportional to its temperature if the pressure and the number of particles is constant this sta
vlada-n [284]

Answer:

Charle's law.

Explanation:

Charle's law:

According to Charle's law:

The volume of gas is directly proportional to the temperature when pressure and number of moles of gas are kept constant.

Mathematical expression:

V ∝ T

V = KT

V/T = K

when temperature is changed from T₁ to T₂ and volume is changed from V₁ to V₂.

V₁/T₁ = K    and   V₂/T₂ = K

V₁/T₁ = V₂/T₂

Their ratio remain constant for same amount of gas at same pressure.
