They would stop rotating meaning one side would have no sun the other would, meaning no crops no water = death
Energy of wave depends on its amplitude and it is given as
here k = constant
A = amplitude
so energy will increase or decrease depends on the amplitude of the wave
So here if we need to check which wave has lower energy then we need to compare the amplitude.
If the amplitude is less then energy must be less
So please check in the figure that which wave out of A and B has lesser amplitude to find out the wave of lesser energy
Complete Question
The accepted speed of sound at atmospheric pressure and 0 *C is 331.5 m/s. The speed of sound increases 0.607 m/s for every *C. Calculate the speed of sound at the temperature of your room(70F) and compare your measured value to the accepted value.
Answer:
Explanation:
From the question we are told that:
Speed of sound at Temperature
Rate of Speed increase
Generally the equation for Temperature in Celsius is mathematically given by
Therefore speed at Tc
Answer:
Explanation:
For flow of heat through conduction , the formula is
Q = KA( T₂ -T₁ ) / d where K is thermal conductivity of material , A is surface area , T₂ - T₁ is temp diff .
Thermal conductivity of aluminum is 205 W /m.s
Surface area of cane = 2π r² + 2π r h where r is radius and h is height of cane .
A = 2π r ( r + h )
= 2 x 3.14 x 1.3 x .0254 ( 1.3 x .0254 + 4.83 x .0254 )
= .20736 ( .033 + .12268 )
A = .03228 m²
thickness d = .12 x 10⁻³ m
Putting the values ,
Q = 205 x .03228 x ( 25 - 4 ) / .12 x 10⁻³
= 1158 x 10³ J /s
Answer:
10.028%
Explanation:
= Angle between polarizer
The polarized light after passing through first polarizer
The polarized light after passing through second polarizer
The polarized light after passing through third polarizer
The percent of the light gets through this combination of filters is 10.028%
