Answer:
176.9N
Explanation:
The following data were given
wire length,L=37cm=0.37m
linear density=18g/m
tube length,=192cm=1.92m,
speed of sound,v=343m/s
Since it is an open-closed tube, the second harmonic frequency is expressed as

The relationship between the tension, linear density and second harmonic frequency is expressed as

I would say A classical conditioning definitely demands a pairing of two stimuli
hope i helped
Explanation:
The following measures can be taken to prevent or control high temperature caused by thermal pollution:
1. Heated water from the industries can treated before discharging directly to the water bodies.
2. Heated water from the industries can be treated by the installation of cooling ponds and cooling towers.
3. Industrial treated water can be recycled for domestic use or industrial heating.
4. Through artificial lakes: In this lake Industries can discharge their used or heated water at one end and water for cooling purposes may be withdrawn from the other end. The heat is eventually dissipated through evaporation.
Answer:
719
Explanation:
Conversion
1 picometer (pm) is equivalent to
meter
1 micrometer is equivalent to
meter
To find the number of layers, we divide the overal leaf thickness by the thickness of one atom hence dividing tex]0.125 × 10^{-6}[/tex] meter by
meter we get that the number of sheets will be as follows

Therefore, they are approximately 719 sheets
