"Period" and "frequency" of waves and oscillations are simple reciprocals. They're not related to the wavelength or speed.
Period = 1 / frequency
Period = 1 / 23.4 Hz
<em>Period = 0.043 second</em>
It is electronegativity the property of an atom which increases with its tendency to attract the electrons of an bond
The difference is that physical weathering is a process that weathers rock without a chemical reaction or change. Chemical weathering changes the identity of rocks and it involves a chemical reaction or change.
Answer:

Explanation:
Since all the four charges are equidistant from the position of Q
so here we can assume this charge distribution to be uniform same as that of a ring
so here electric field due to ring on its axis is given as

here we have
x = b
and the radius of equivalent ring is given as the distance of each corner to the center of square

now we have

so the force on the charge is given as


Answer:
They both have the same angular speed.
Explanation:
The mathematical formula for angular speed is:

where
is angular speed,
is a constant, and
is the period (the time it takes the marry-go-round to complete a lap).
What we can see from the formula is that, since the
does not change its value, the angular speed depends only on the period T.
In this case for both the children closer to the outher edge and for the children closer to the center, the time to complete a lap is the same, because the time does not depend on where they are sitting in the marry go round. This means that the period for both is the same.
Thus, since the period for both is the same, the angular speed given by
will also be the same
