You could attach both springs to the ceiling and hang the same mass from both. The one that stretches less has the larger spring constant value.
Answer:
i. The radius 'r' of the electron's path is 4.23 × m.
ii. The frequency 'f' of the motion is 455.44 KHz.
Explanation:
The radius 'r' of the electron's path is called a gyroradius. Gyroradius is the radius of the circular motion of a charged particle in the presence of a uniform magnetic field.
r =
Where: B is the strength magnetic field, q is the charge, v is its velocity and m is the mass of the particle.
From the question, B = 1.63 × T, v = 121 m/s, Θ = (since it enters perpendicularly to the field), q = e = 1.6 × C and m = 9.11 × Kg.
Thus,
r = ÷ sinΘ
But, sinΘ = sin = 1.
So that;
r =
= (9.11 × × 121) ÷ (1.6 × × 1.63 × )
= 1.10231 × ÷ 2.608 ×
= 4.2266 ×
= 4.23 × m
The radius 'r' of the electron's path is 4.23 × m.
B. The frequency 'f' of the motion is called cyclotron frequency;
f =
= (1.6 × × 1.63 × ) ÷ (2 × × 9.11 × )
= 2.608 × ÷ 5.7263 ×
= 455442.4323
f = 455.44 KHz
The frequency 'f' of the motion is 455.44 KHz.
Answer:
In a nutshell, a scientific law predicts what happens while other laws devised by people usually proposes why certain things happen.
Explanation:
A scientific law is one that predicts the results of certain initial conditions. In order words, it predicts what will happen when certain conditions are fulfilled. A very good example is Newton's 3 laws of motion where like the third law which says to every action, there is an equal and opposite reaction or like in the first law which says a body at rest will remain at rest unless it is acted upon by an external force.
Whereas, other laws devised by people usually provides the most logical explanation as to why things happen the way they do. For example explaining why some children develop certain peculiar health issues when they are newly born.
