Answer:
Please find the answer in the explanation.
Explanation:
When you try to move the magnet back and forth between the two coils, the motion of the magnet will be oscillatory and this action will cause current and EMF to induce
According to law of Faraday, current or EMF will be induced when a magnet is moved in the presence of coils
If the magnet continues to move back and forth between the two coils, what might be causing this will be the presence of the induced electromagnetic force between the two coils.
Answer:
G. 93 m
Explanation:
Applying the equation of motion,
s = ut + 1/2at²........................ Equation 1
Where s = distance, u = initial velocity, t = time, a = acceleration.
Given: u = 0 m/s ( at rest), a = 3.3 m/s², t = 7.5 s.
Substitute into equation 1
s = 0(7.5) + 1/2(3.3)(7.5)²
s = 0 + 185.625/2
s = 185.625/2
s = 92.8
s ≈ 93 m
Hence the right option is G. 93 m

Answer:option D
2Mg + O2 ------> 2 MgO
Fundamental frequency,
f=v2l=T/μ−−−−√2l
=(50)/0.1×10−3/10−22×0.6−−−−−−−−−−−−−−−−−−−√
=58.96Hz
Let, n th harmonic is the hightest frequency, then
(58.93)n = 20000
∴N=339.38
Hence, 339 is the highest frequency.
∴fmax=(339)(58.93)Hz=19977Hz.

What is frequency?</h3>
In physics, frequency is the number of waves that pass a given point in a unit of time as well as the number of cycles or vibrations that a body in periodic motion experiences in a unit of time. After moving through a sequence of situations or locations and then returning to its initial position, a body in periodic motion is said to have experienced one cycle or one vibration. See also simple harmonic motion and angular velocity.
