I think answer is A. The Brightness of a Star
Answer:
<em>20cm</em>
Explanation:
<em>A coil wire comprises of 5 turns, it has a current of 2mA </em>
<em>A net magnetic field at the center of B is equal to Mu over 40 end fractions times T</em>
<em>The radius of a coil of wire with N turns is r = 0.28 m. A clockwise current of Icoil = 1.0 A flows in the coil,</em>
<em>Therefore 40/2mA = 20</em>
The last sentence is a little vague.
However, I will assume that by the last sentence you meant
![Reaction~Rate=[CH_3Cl][H_2O]](https://tex.z-dn.net/?f=Reaction~Rate%3D%5BCH_3Cl%5D%5BH_2O%5D)
The reaction order respective to any substance is the value of the exponent on that substance in the Reaction Rate equation.
We see that the exponent on both the substance is 1 so the reaction order with respect to each substance is 1.
It slows down. The molecules/particles aren't as close together, resulting in slower movement.
