They tell you what the scientists are looking for in the experiment, "find out how strong the net below a trapeze should be". Using that you find out that the only question that questions the strength of the net is B.
<h2><u>
Answer:</u></h2>
<u></u>
<u>Force = kgm/s² ⟶ Newton</u>
<h2><u>
Explanation:</u></h2>
<u></u>
According to the formula we've learnt,
- Force = mass × acceleration.
To find force in terms of base units, we must first identify the base SI units of mass & acceleration.
- Base SI unit of mass = kg (kilogram)
- Base SI unit of acceleration = m/s² (meter per second squared)
So, the base unit of force is,
- Force = mass × acceleration.
- <u>Force = kgm/s² ⟶ Newton</u>

Hope it helps!

B is the correct answer
y=Asin(wt-kx)
A=amplitude
f=frequency
x=wavelength
since refraction is not on the wave formula,then option B is the correct answer
rotational kinetic energy of it's particles
