Answer:
Ω
Explanation:
Given that
d(min,0)= 4 cm
d(min,1)= 14 cm
Voltage standingwave ratio = 1.5
Zo = 50 Ω
We know that
d(min,1) - d(min,0) = λ/2
Now by putting the values
14 - 4 = λ/2
λ = 20 cm
We also know that
β=2π/λ
β=2π/0.2 = 10π rad/m
So we can say that
θr= 2β d(min,n) - (2 n + 1)π rad
θr=2×10π ×0.04 −π = -0.2 π rad
We know that
π rad = 180 °
θr= = -0.2 π rad= -36 °
We know that
Here S= 1.5
by putting the values
Ω
Completed question:Suppose one speaker is driven at 570 Hz and the other at 554 Hz. What is the beat frequency in Hz? The average frequency in Hz?
Answer:
Beat frequency= 16Hz
Average frequency = 562Hz
Explanation:
Beat frequency f = f2-f1
Where f2 is frequency of source with higher frequency
f1 is frequency of source with lower frequency
f1= 554Hz, f2= 570Hz
beat frequency (f) = 570 -554
= 16Hz
Average frequency =
=
Becuase of the earths gravitational pull you wont feel it because the earth is pulling you already and you arent big enough to feel the pull between the 2
A pure substance is a substance that contains only one type of atom or molecule. Homogeneous mixture is commonly referred to solution as there is uniform distribution all over the mixture while in a heterogeneous mixture consists of different phases or substances that are visible.
A compound is substance containing two or more elements that are chemically bound together. Therefore, coleslaw (a salad containing finely shredded cabbages and carrots and a creamy dressing) is a heterogeneous mixture.
