If you know the density and the mass of an object, what formula would you use to calculate its volume?

The set equation relating mass, density, and volume is D=m/v or density equals mass divided by volume. 2 Plug your values into the equation. If the density of your object is 500 kg/m 3 (kilograms per cubic meter), then you put 500 in place of the D for 500=m/v.

Explanation:

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
