The coefficient of friction between the soap and the floor is 0.081
If Juan steps on the soap with a force of 493 N, this is her weight, W. This weight also equals the normal reaction on the floor, N.
We know that frictional force F = μN where μ = coefficient of friction between soap and floor.
So, μ = F/N
Since F = 40 N and N = W = 493 N,
μ = F/N
μ = 40 N/493 N
μ = 0.081
So, the coefficient of friction between the soap and the floor is 0.081

Answer:
Explanation:
mass of electron in amu = .000549
mass of electron = mass of proton
total mass of electron and proton = 2 x1.098 x 10⁻³ = 2.196 x 10⁻³ amu
1 amu = 931 x 10⁶ eV
2.196 X 10⁻³ amu = 2.196 x 931 x 10³ eV
= 2.044 X 10⁶ eV.
= 2044 X 10³ ev
So minimum energy required = 2044 x 10³ eV.
Wavelength of photon required = 12375/2044 x 10³ A
= 6.054 X 10⁻³A. =6.054 X 10⁻¹³ m
frequency of photon = 3 x 10⁸/6.054x 10⁻¹³
= .4955 x 10¹⁶Hz.
= 4.955 x 10¹⁵ Hz
Answer:
The answer is neutrons and mass number
Explanation:
Answer:
O ksm/s
Explanation:
before collision,
Velocity =0
So,momentum of the bottle before collision=mass ×velocity
=mass×0
=0 kgm/s
The solids whose particles occur in a definite pattern are called crystaline solids.
<h3>What is a crystalline solid?</h3>
The term crystalline solid has to do with the type of solid in which the atoms that components that make up the solid are all in definite positions and occur in a regular repeating pattern.
The particles of a solid are found in fixed positions. The solids whose particles occur in a definite pattern are called crystaline solids.
