The correct answer is - 75-80%.
The haze is a hazardous occurrence. It is a slight obscuration of the lower atmosphere, and the cause for its occurrence are the fine suspended particles. Thus we can conclude that the haze is actually caused by pollution of the air.
While the haze typically is a dry air phenomenon, it can also be a wet one if the conditions are right, though that happens relatively rarely. If the humidity in the air is 75-80% than the tiny aerosol particles of the dry haze start to act as condensation nuclei, resulting in a wet haze.
The answer to question 9 is the last one, be elevator is 10m/s and the other is -10m/s as they are going in different directions so one will be negative
The magnetic field lines
around a long wire which
carries an electric current
form concentric circles
around the wire. The
direction of the
magnetic field is
perpendicular to the wire
and is in the direction
the fingers of
your right hand
would curl if you
wrapped them
around the wire
with your
thumb in the direction
of the current.
hope it helps you
Answer:
240.59 N
Explanation:
We are given that
Mass per unit length=m/l=
Fundamental frequency,f=146.8 Hz
Tension=T=82.4 N
Mass per unit length=
We have to find the tension.
Velocity,v=
New tension,T'=
Hence, the string should have tension 240.59 N so that its fundamental frequency is 146.8 Hz
