Both have positive charge. In fact, an alpha particle IS a nucleus of a Helium atom.
It depends on if it is a sound wave or light wave
The period of the pendulum is given by the following equation
T = 2<span>π * sqrt (L/g)
Where g is the gravity (free fall acceleration)
L is the longitude of the pendulum
T is the period.
We find g.............> (T /2</span>π)<span>^</span><span>2 = L/g
g = L/(</span>T /2π)^2...........> g = 22.657 m/s^2
Which of these would best define sound intensity?
A) how fast the wave is travelling
<u>B) the frequency of the sound wave the power of the sound wave per unit area the mass of the wave divided by its volume</u>
The correct option is: Option (D) not turn at all.
Explanation:
As the bar magnet is at rest, there is no change in magnetic flux. It means the change in magnetic flux in the magnetic flux in the loop is zero. Hence the induced current in the loop is zero and the loop will never turn at all. Therefore, the correct option is (D).
