Well for question 1, the answer would be your opinion on which graph is easier to read and understand better.
for the second question. the one to get specific data would be the table chart because you can read the numbers easily rather than trying to guess on the bar chart wear the bars are actually at are kinda close to an exact number, but not really the number you were thinking
Answer:
Because it unites particle and wave nature.
Explanation:
De Broglie wavelength can be defined as the,
Here, h is planks constant, m is the mass of electron, v is the velocity of electron.
Since the de Broglie wavelength can behave like the photon wavelength with respect to the momentum
It unites particles and waves nature ,so De Broglie wavelengths is probability waves associated with the wave function according to physicists.
The coefficient of kinetic friction (μ) between the block and the table is 0.4.
<h3>
What is kinetic friction?</h3>
This sis the frictional force between an object in motion with the surface in contact.
μN = ff
where;
- N is normal reaction due to weight of the block
- ff is frictional force
- μ is coefficient of friction
μ = ff/N
μ = 8/20
μ = 0.4
Thus, the coefficient of kinetic friction (μ) between the block and the table is 0.4.
