Physics

Question 1

Formula for density

Answer 1

Mass/volume

Question 2

How to find density of regular shaped object

Answer 2

First find the dimensions of the object using a ruler
Calculate the volume of the object by length x width x height
Then find the mass by weighing the object on a scale
Then substitute numbers into the equation density=mass/volume
Then divide the mass amount and volume amount by each other
Then that is the density

Question 3

How to find density of irregular shaped object

Answer 3

1) Place object on measuring scale
2) This is the mass value
3) Fill eureuka can with water
4) put added beaker next to eureuka can
5) place the object in eureuka can and let the water drip into the beaker
6) After dripping stops put all the water from beaker into a measuring cylinder
7) This is the volume
8) Substitute numbers back into density=mass/volume
9) Divide mass by volume
10) This is the density value

Question 4

Equation for Wavespeed

Answer 4

Wavespeed = frequency x wavelength
