Answer:
H = 70.4 m
Explanation:
Here first of all the balloon will drop to the the floor under free fall motion and then the sound of splash will come up at constant speed
so we will say that if the total height is H
so the time to fall is given as

now we have

also we know that the time to come the sound upwards is

so we will have


now plug in all data

by solving above equation we have
H = 70.4 m
well its a productive activity that one takes part in due to being broke
<h3>Question:</h3>

Uhuru Kenyatta
Answer:

Explanation:
We know that impedance of a RLC circuit is given by 
So
here R is resistance
is inductive reactance and
is capacitive reactance
To minimize the impedance
should be zero we know that 
So 


We know that 
So 

Where f is resonance frequency
