Explanation:
Bats emit ultrasound waves: in air, ultrasound waves travel at a speed of
The frequency of the waves emitted by this bat is:
Therefore we can find the wavelength of the wave emitted by the bat by using the relationship between speed, frequency and wavelength:
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 .
