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
The distance between object P1 and its image formed is determined as 36 m.
<h3>
Distance of the image</h3>
The distance of the image formed by object P1 is calculated as follows;
In a plane mirror; object distance = image distance
image distance of P1 = 18 m
distance between object and image = 18m + 18 m = 36 m
Thus, the distance between object P1 and its image formed is determined as 36 m.

Explanation:
Answer: A confederation is a union of sovereign states, united for purposes of common action often in relation to other states.
Explanation:
Confederalism represents a main form of inter-governmentalism, this being defined as any form of interaction between states which takes place on the basis of sovereign independence or government.
Answer:
Tension, T = 105.09 N
Explanation:
Given that,
Length of the string, l = 0.33 m
Mass of the string,
Fundamental frequency, f = 440 Hz
The expression for the speed in terms of tension is given by :
So, the tension in the string is 105.09 N.
