Solution :
The nuclear reaction for boron is given as :

And the reaction for Cadmium is :
![$^{113}\textrm{Cd}_48 + ^{1}\textrm{n}_0 \rightarrow ^{114}\textrm{Cd}_48 + \gamma [5 \ \textrm{MeV}]$](https://tex.z-dn.net/?f=%24%5E%7B113%7D%5Ctextrm%7BCd%7D_48%20%2B%20%5E%7B1%7D%5Ctextrm%7Bn%7D_0%20%5Crightarrow%20%5E%7B114%7D%5Ctextrm%7BCd%7D_48%20%2B%20%5Cgamma%20%5B5%20%5C%20%5Ctextrm%7BMeV%7D%5D%24)
We know that it is easier that to shield or stop an alpha particle (i.e. He nucli) as they can be stopped or obstructed by only a few centimetres of the material. However, the gamma rays ( γ ) can penetrate through the material to a greater distance. Therefore, we can choose the first one.
A good visual lead is 20-30 seconds from the front of the vehicle, focusing in the center of the path of travel. Searching 20 to 30 seconds ahead, gives you time to assess within the next ..12-15 seconds, actions you may need to take to control an approaching risk.
Discussion:
Keeping eye focus centered in a path of travel at an interval of 20 to 30 seconds away from the vehicle is critical to gaining enough info. as possible in the driving scene. Good targeting sets up good sight lines for referencing and good peripheral fields for observing changes.
- It is important to look ahead 12-15 seconds into your target area as one drives. Compromise. space by giving as much space to the greater of two hazards.

Answer:
Sedimentation is not a good method.
Explanation:
We need to apply Stoke laws and assume that is valid here.
So,

Replacing the values,

Here then we calculate the time,

Where x= Distance, v= velocity

To calculate the surface required we need first to calculate the volume through the volume,
So,

Then,

Here we can calculate the surface

<em>So, the requeriment of Area of tank and settlement time is huge, it's not a practical method.</em>
Answer:
112.5 watts
Explanation:
The output voltage (V) = 15 volts
The equivalent resistance for the speakers connected in parallel (
) is gotten by using the formula:

The current flowing through the amplifier (I) is:
I = V /
= 15 / 2 = 7.5 A
The audio power (P) when outputting this maximum voltage is given by:
P = V² /
= I²
. Therefore:
P = V² /
= 15² /
= 112.5 watts
