NONE of the choices is a correct answer.
Density is (mass) DIVIDED BY (volume).
The volume of the black cube is
2 x 2 x 2 = 8 cm^3
It's density is 48/8 = 6 gm/cm^3
The volume of the yellow cube is
3 x 3 x 3 = 27 cm^3
Its density is 135/27 = 5 gm/cm^3
The black one is denser because the RATIO of its mass to its volume is greater.
The cubes are made of different substances.
The density only depends on the substance. It doesn't matter HOW MUCH of the substance there is. It's the RATIO that counts.
The black one would be denser even if one cube or the other was the size of a supertanker.
Answer:
I might be able to help, but I also might not. I need to check if I can get you the answer.
Explanation:
The speed of an object is measured by calculating the distance it travels per unit time.
The formula in Physics for calculating speed is = distance/ time.
Since an object at rest is not covering any distance, the speed is always assumed to be 0 m/s.
Answer:
I think it is 2.5 kg.
Explanation:
I can say you do:
Fnet = m * a
So, you want to find mass:
m = Fnet / a
So, the answer you will receive is 2.5
I believe it is because the salt supports the weight of the egg
