Using data from ms. baltzers students, they found the mass of a piece of brown metal was 14.2 grams, and the volume of that same piece of metal was 1.8 ml. what is the density of the brown metal?

d = 7.9 g/mL

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

Mass of brown metal = 14.2 g

Volume = 1.8 mL

Density = ?

Solution:

d = m/v

d = 14.2 g/1.8 mL

d = 7.9 g/mL

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

personal, she chose to do it.
