Answer:
Toasting in a toaster is usually considered by (infra red) radiation. But the hot coils touch the toast so an element of heating by conduction occurs as well.
Explanation:
Amplitude: the height of the wave
wavelenght: the distance betweeen adjacent crests
period: the time it takes for one complete wave to pass a given point
Answer:
a) f = 809.5 Hz
, b) f = 1619 Hz
Explanation:
The condition for destructive interference from the speakers is
Δr / lam = Ф / 2π
λ = Δr 2π / π
We substitute
λ = 0.21 2 π/π
Lam = 0.42 m
Now let's use the ratio of the speed of sound and the wavelength and the frequency
v = λ f
f = v /λ
f = 340 / 0.42
f = 809.5 Hz
b) in this case the intensity is maximum
Lam = Δr 2π / 2π
Lam = 0.21 m
fF= v / lam
f = 340 / 0.21
f = 1619 Hz
First let’s pick one at random
Less than 5 percentile
That means they lined 100 kids up and less than 5% of them are that certain weight.
So if you apply this to every option you will see the answer is
A). Less than 5 percentile
Answer:
<h2>
Work done by the gas is given as</h2><h2>
</h2>
Explanation:
As we know that the process is isothermal so here work done is given as
here we know that
now we have
so we have
