Answer:
The coefficient of friction is 0.05
Explanation:
Given that,
When Isabella pushes a box of mass 5.25 kilograms with a force of 15.7 newtons.
It accelerates by a rate of 2.50 m/s²
Let coefficient of friction be μ
Force (F) = 15.7 N
Acceleration (a) = 2.5 m/s²
Mass (m) = 5.25 kg
Gravity (g) = 9.8 m/s²
Balanced equation of box to move
F - μmg = ma
15.7 - μ(5.25)(9.8) = (5.25)(2.50)
Hence, The coefficient of friction is 0.05

Answer:
The atomic mass unit is 1/12 of an atom of carbon 12, and is a very small amount to represent in kilograms:
is atomic mass unit.
This is why the benefits of the atomic mass unit is that it makes the representation of atomic masses easier in terms of the simplicity of the numbers that are used to represent the masses. Also using the atomic mass unit it is easier to compare the masses of different atoms, These numbers would be very small and would require negative powers of 10 to represent them, so it is more convenient to use the atomic mass unit.
