Answer:
v = √ k e²/m r
Explanation:
From the classical point of view the force between the nucleus and the electron is electrostatic
F = q E
q = e
we apply Newton's second law
F = m a
where the centripetal accelerations
a = v² / R
we substitute
e E = m v² / r
v² = ( e/m E r)
the electrioc field is
E = k q/r²
v² = e/m k e/r
v = √ k e²/m r
I couldnt type it out so here's a picture
Answer:
10 N
Explanation:
I assume there is no friction and we are only worrying about the horizontal direction. If so we use the formula F=MA to get F= 2 * 5 = 10 N
Answer:
Explanation:
Speed multipliers are useful when an object needs to move a further distance or at a higher speed. Some examples are wheels and axles and third class levers. Machines can be either simple or complex. Simple machines are machines that only use one type of machine, such as a lever or an inclined plane.
