Answer:
The velocity of the other fragment immediately following the explosion is v .
Explanation:
Given :
Mass of original shell , m .
Velocity of shell , + v .
Now , the particle explodes into two half parts , i.e
.
Since , no eternal force is applied in the particle .
Therefore , its momentum will be conserved .
So , Final momentum = Initial momentum

The velocity of the other fragment immediately following the explosion is v .
1. Light Travelling from denser medium to less dense medium
2. Light Travelling from less dense medium to denser medium
Answer:

Explanation:
From the question we are told that:
Period of spring 
Initial Position of Mass 
Final Mass period 
Generally the equation for the Mass location is mathematically given by



Because the scientific method can go around in a circle as many times as neccisary to get the results you need
Answer:
As Per Provided Information
Velocity of wave v is 10m/s
These ocean wave passes a stationary point every 5 s ( It's time period)
First we calculate the frequency of ocean wave .
<u>Using</u><u> Formulae</u>

here
v is the velocity of wave .

Now calculating the wavelength of the wave .
<u>Using </u><u>Formulae </u>

Substituting the value and we obtain

<u>Therefore</u><u>,</u>
- <u>Wavelength </u><u>of </u><u>the </u><u>wave </u><u>is </u><u>100 </u><u>metres</u><u>.</u>
