Answer:
When a system is at equilibrium in terms of concentration what happens is that the rate of change of the concentration of the product and the reactants does not vary or change with time.
Explanation:
What is equilibrium?
A chemical reaction is in equilibrium when the concentrations of reactants and products are constant - their ratio does not vary.
Equilibrium does not necessarily mean that reactants and products are present in equal amounts. It means that the reaction has reached a point where the concentrations of the reactant and product are unchanging with time, because the forward and backward reactions have the same rate.
The answer is Fuse, the Fuse has a low melting point
Answer:
<h3>The answer is 0.54 m</h3>
Explanation:
The wavelength of a wave can be found by using the formula
![\lambda = \frac{c}{f} \\](https://tex.z-dn.net/?f=%20%5Clambda%20%3D%20%20%5Cfrac%7Bc%7D%7Bf%7D%20%20%5C%5C%20)
where
c is the velocity
f is the frequency
So we have
![\lambda = \frac{457}{841} \\ = 0.543400713...](https://tex.z-dn.net/?f=%20%5Clambda%20%3D%20%20%5Cfrac%7B457%7D%7B841%7D%20%20%5C%5C%20%20%3D%200.543400713...)
We have the final answer as
<h3>0.54 m</h3>
Hope this helps you
Answer:
r = 50[m]
Explanation:
Since the instrument has an operating or range radius, we must calculate this working distance or radius. We can determine the working area with the values that were given to us.
![A=\frac{70W}{0.0089\frac{w}{m^{2} } } \\\\A=7865.16[m^{2} ]](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B70W%7D%7B0.0089%5Cfrac%7Bw%7D%7Bm%5E%7B2%7D%20%7D%20%7D%20%5C%5C%5C%5CA%3D7865.16%5Bm%5E%7B2%7D%20%5D)
Now using the area of the circle we can find the radius.
![A=\pi *r^{2} \\7865.16=\pi *r^{2} \\\\r=\sqrt{\frac{7865.16}{\pi } } \\r=50[m]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%2Ar%5E%7B2%7D%20%5C%5C7865.16%3D%5Cpi%20%2Ar%5E%7B2%7D%20%5C%5C%5C%5Cr%3D%5Csqrt%7B%5Cfrac%7B7865.16%7D%7B%5Cpi%20%7D%20%7D%20%5C%5Cr%3D50%5Bm%5D)
