According to the question; The output power is 0.643W.
<h3>What do you mean by power?</h3>
Power is the quantity of energy that is transported or transformed per unit of time in physics. The watt, which is equal to one joule per second in the International System of Units, is the unit of power. Power may also be referred to as activity in earlier writings. A scalar concept is a power.
According to the question:
Power, P₁ = 150W
Sound intensity level, β = 103db
Distance, d = 1.60m
The sound intensity level is β = 10log(I/I₀)
Reference intensity I₀ = 10⁻¹²
By solving, Intensity, I = 0.02w/m²
Power output P₀ = (4πd²) I
P₀ = 0.643W

Higher the pressure the air would spread apart causing the paper to move to the other side. So higher pressure causes the papers to move farther apart.
Answer:
the table is strong enough to hold the metal
Answer:
The procedure is the plan for how you will conduct your experiment.
Explanation:
Answer:
646.6 nm
Explanation:
Using the data given, we fit a linear model :
Spectroscope Readings Known Helium Wavelengths (nm)
3.65 388.9
4.75 486.6
4.90 501.6
5.65 587.6
6.45 667.8
7.00 706.5
Using technology like excel to fit the model, the regression model obtained is :
Y = 97.96582X + 27.48458
Where, y is the predicted or corrected wavelength value.
This mod could be used to calculate the corrected wavelength for a given Spectroscope value :
Given a Spectroscope value of 6.32 ; the corrected wavelength is obtained by replacing x in the equation by 6.32 and calculate y ;
Y = 97.96582X + 27.48458
x = 6.32
Y = 97.96582(6.32) + 27.48458
Y = 619.1439824 + 27.48458
Y = 646.6285624
Corrected wavelength value is : 646.6
