Explanation:
Changes in the higher authorities or managers or coworkers can be a warning sign before a layoff, however, a company or organization needs to give an official notice before a particular time period before the layoff.
The layoff is a temporary suspension or permanent termination from the employment of an employee due to reasons related to business such as reducing manpower or staff and less work in the organization. These reasons can lead to a change in the behavior of the managers, coworkers, and subordinates.

Answer:
Explanation:
This is a case of interference of sound , akin to YDSE in optics .
Here, like interference dark and bright fringes, region of silence and intense sound will be formed due to destructive and constructive interference respectively.
Here d = distance between two sources = 5 m
D = distance of source and screen = 12m
position of first destructive interference
= λ D /2d
1 = λ 12 /2x 5
λ = 5 / 6 m
frequency = v / λ
= 343 x 6/ 5
= 411.6 Hz
Answer:
21.2 m
Explanation:
The current in the wire is given by Ohm's law:
where V is the voltage of the battery and R is the resistance of the wire.
The resistance of the wire is directly proportional to the length of the wire, so we can write:
where k is a constant and L is the length of the wire. Substituting into the first equation,
We can rewrite this equation also as
where the term on the left is a constant (because the voltage of the battery does not change). So, we can write:
where:
is the current in the first situation
is the length of the wire in the first situation
is the current in the second situation
is the length of the wire in the second situation
Re-arranging the formula, we can find the value of L2:
