A scientist has two cubes, A and B, that are made of unknown substances. Both cubes have a mass of 15g. Cube A has a volume of 35 cm^3 and cube B has a volume of 70 cm^3. Explain how you know which cube has a greater density.

(i will give brainlist)

Cube A

Explanation:

IF MASS IS SAME , THE CUBE WITH SMALLER VOLUME HAS A GREATER DENSITY

IN THIS CASE , CUBE A HAS LESS VOLUME SO GREATER DENSITY

please give brainliest

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
