So the first thing you need to do is convert the wavelength from centimeters to meters. This is quite easy, all you do is divide by 100.
Then I'm assuming the equation they're talking about is c = f λ.
c = the speed of the wave
f = the frequency of the wave
<span>λ = the wavelength
</span>
So all you need to do is multiply the frequency they gave you by the wavelength you calculated.
TOP ROW
f = 10 hz
<span>λ = .1 m
</span>c = 10×.1
c = 1 m/s
2ND ROW
<span>f = 2.5 hz
</span><span>λ = 10</span>÷100
λ = .1 m
c = 2.5×.1
c = .25 m/s
3RD ROW
f = 30 hz
λ = 2÷100
<span>λ = .02
</span>c = 30×.02
c = .6 m/s
BOTTOM ROW
f = 50 hz
<span>λ = 1</span>÷100<span>
</span><span>λ = .01
</span>c = 50×.01
c = .5 m/s
Answer:
Sound waves does not include in EM Spectrum
So, option C is your answer!
Explanation:
mark me brainliest!!
The position compared to that of home is a reference to displacement, I believe.
Displacement = x total - x initial
So I believe the answer is 5 blocks due north (if you’re walking linearly from your home), unless the questions is referring to relative displacement, in which then you’d need to use the Pythagorean theorem to find the hypotenuse between both positions. And then you’d have to find theta for the degrees between the south direction and the other unmentioned direction. But I don’t think that’s the case.
Distance refers to x total and doesn’t care for direction, as this refers to a scalar quantity opposed to a vector. Thus the equation is just
d = x
So 8 blocks + 3 blocks = a distance of eleven blocks walked total
Answer:
Heat transfer is an engineering discipline that concerns the generation, use, conversion, and exchange of heat (thermal energy) between physical systems.
