If you have an object that takes up 4 cubic centimeters of space and has a mass of 2g, what is the density of that object?

Answers

Answer 1
D=mass/volume in kg/m^3

4cm3 divided by 100^3 = 4x10^-6 (volume)

Mass =2g to kg 0.002kg

0.002/4x10^-6= 500kg/m3



Answer 2
2g per cubic cm
mass divided by volume equals density

Answers

B is correct but I’m pretty sure a is also correct

Explanation: kidneys do not "remove" urine from the body. They filter waste in the blood which then forms the urine. The kidney thus functions in filtration of waste products from the blood leading to urine formation.

Why is the sun's renewable energy important to animals?

1. they are able to directly convert the sun's energy into food
2. they eat plants that get their energy from the sun
3. the suns energy isn't important to animals because they don't depend on the plants
4. they absorb the sun's energy through their skin as a way of staying warms

Answers

Answer:

2. they eat plants that get their energy from the sun

Explanation:

Based on the way energy flows through an ecosystem, animals could not survive if they did not have the source of plants. So, the sun's renewable energy is important to animals because the sun helps them grow their food.

I hope this helps and makes sense!

Answer:

4. they absorb the sun's energy through their skin as a way of staying warms
