Density because any object that is more dense than water (density of 1. I forget the units) sinks, and any object less dense than water floats.
Answer:
The coefficient of rolling friction for the tire under low pressure is 0.0342.
Explanation:
Two bicycle tires are set rolling with the same initial speed of 4.00 m/s
Final speed of both the bicycle, speed is reduced by half is measured, v = 2 m/s.
Here,

Using third equation of motion as :

So, the coefficient of rolling friction for the tire under low pressure is 0.0342.
Answer:
Zero, the support force and gravitational force together equal a zero net force
Explanation:
Between the bumps and dips of two surfaces. SO the answer is 2 surfaces. Hope this helps! :)

Answer:
Densities
Explanation:
When we talk about density, one of the things that come to our mind is actually how heavy something is.
If i have substances that possess different densities, i will notice that i can not really mix them because they will separate and the heavier substance will be at the bottom while the lighter substance will be at the top.
Hence the two substances separated due to difference in density.
