Answer:
500 nm.
Explanation:
The wavelength of harmonic oscillator can be calculated by the formula,
Here, is the longest wavelength, and n is the number of order.
Now given that the longest wavelength is 1000 nm.
Now calculate second longest wavelength,
Therefore, the second longest wavelength is 500 nm.
Answer:
1.3m/s²
Explanation:
Given values in the first part: acceleration a, time t₁:
1) velocity v₀
2) height h₀
Given values in the second part: acceleration -g, time t₂:
3) height h
Combining equations 1,2,3 and setting h to zero:
Solve for a with t₁ = 4s and t₂=2.1s:
Complete Question
Two stationary positive point charges, charge 1 of magnitude 3.25 nC and charge 2 of magnitude 2.00 nC , are separated by a distance of 58.0 cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges.
Required:
What is the speed of the electron when it is 10.0 cm from the +3.25-nC charge?
Answer:
The velocity is
Explanation:
From the question we are told that
The magnitude of charge one is
The magnitude of charge two
The distance of separation is
Generally the electric potential of the electron at the midway point is mathematically represented as
substituting values
Now when the electron is 10 cm = 0.10 m from charge 1 , it is (0.58 - 0.10 = 0.48 m ) m from charge two
Now the electric potential at that point is mathematically represented as
substituting values
Now the law of energy conservation ,
The kinetic energy of the electron = potential energy of the electron
i.e
where q is the magnitude of the charge on the electron with value
While m is the mass of the electron with value
