There are three basic steps in a nuclear fission chain reaction are Initiation, Propagation, Termination.

<h3>What are the three steps of nuclear fission ?</h3>

1. Initiation

The nuclear fission of $U_{235} ^{92}$ is started by the absorption of a neutron; a single atom must react in order for the chain reaction to begin.

2. Propagation:-

With each stage producing additional product, this component of the process is repeated repeatedly. When $U_{236} ^{92}$ splits apart, neutrons are released, which start the nuclear fission of more uranium atoms.

3. Termination:

The chain will come to an end eventually. Termination might take place if the reactant $U_{235} ^{92}$ is exhausted or if the subsequent neutrons in the chain leave the sample without being absorbed by $U_{235} ^{92}$ .

Answer:

Distance = 16.9 m

Explanation:

We are given;

Power; P = 70 W

Intensity; I = 0.0195 W/m²

Now, for a spherical sound wave, the intensity in the radial direction is expressed as a function of distance r from the center of the sphere and is given by the expression;

I = Power/Unit area = P/(4πr²)

where;

P is the sound power

r is the distance.

Thus;

Making r the subject, we have;

r² = P/4πI

r = √(P/4πI)

r = √(70/(4π*0.0195))

r = √285.6627

r = 16.9 m

when you inhale (breathe in) your ribs move upwards and outwards and your diaphragm moves down. Explain in terms of pressure and

katrin2010 [14]

As you inhale, your ribs move up and out decreasing the internal pressure and increasing the volume of the lungs forcing air into the lungs from an area of externally high pressure in comparison to the low internal pressure.
