Answer:
Amplitude, A = 5 m
Explanation:
Let a progressive wave is given by equation :
.....(1)
The general equation of a progressive wave is given by :
....(2)
Here,
A is the amplitude of the wave
is the angular frequency
k is propagation constant
We need to find the amplitude of the wave.
If we compare equations (1) and (2), we find that the amplitude of the given plane progressive wave is 5 m.
Answer:
Resolution = Wavelength = 252.101 nm
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value
Given, Frequency =
Thus, Wavelength is:
Also, 1 m = nm
So,
<u>Resolution = Wavelength = 252.101 nm</u>
Answer:
Explanation:
Under this condition, . In order to suspend the wire, this magnetic force would have to be equal in magnitude to the gravitational force exerted by Earth on the wire the maximum force at angle
F=ILxB
Now to the suspend the wire so use the maximum force and solve to the current knowing the magnetic field of the earth
∑Fy=0
Solve to I current
I suggest do an toher act is really risk that current for an act
