Answer:
The rotation speed, w, is 2*pi radians/60 seconds = 0.105 rad/s and r = 0.01 m
The flea needs centripetal force given by
Fc = m*w^2/r
That force must come from friction given by
Ff = mu*N = mu*m*g
So
m*w^2/r = mu*m*g
Substitute the data, cancel the m's, and solve for mu.
<h3><u>Answer and explanation;</u></h3>
- <u><em>A neutral sodium atom contains 11 protons, 12 neutrons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1.</em></u> Thus; Sodium atom is neutral whereas sodium ion is a charged species with a charge of +1.
- <u><em>Sodium ion is positively charged. In sodium ion, there are 11 protons and 12 neutrons but 10 electrons</em></u>, i.e., sodium ion contains lesser number of electrons. Additionally,the size of sodium ion is smaller than that of sodium atom.
Answer:
1st law known as low of inertial
2nd law of acelaration and force relationship
3rd law of action and reaction
F = m*a
5000 = 2000 * x
5000/2000 = x
2.5 = x
2.5m/s^2 = a
