Answer:
9.6J+88.2J=97.8J
Explanation:
Here the velocity of the seagull is given,mass is given and its height.
We have to find its mechanical energy my friend.
Mechanical energy=kinetic energy + potential energy.
First we will find kinetic energy.
For calculating kinetic energy we need mass and velocity,which are given here.
So, Ek=

So by substituting the values we get 9.6J.
Now we find the potential energy which is mgh.
By substituting the values we get 88.2J.
Then we add both of those and get 97.8J
I hope this satisfies you and make sure you contact me if it doesn't

Answer:
dissociation of acetic acid (like vinegar) in water
Explanation:
CH3COOH is basically vinegar (aka acetic acid)
dissociation of acetic acid in water
so when you put vinegar in water it makes 2 hydrogen ions (H+) and acetate ( CH3C00 ) a chemical that used in making film
Answer:
0.0000109261200583 s
0.0109261200583
Explanation:
= Distance from right ear = 3 m
s = Distance between ears = 15 cm
v = Speed of sound in air = 343 m/s
Distance between the left ear and the bird

Time

Time difference would be

The time difference is 0.0000109261200583 s
Time period is given by

The ratio is

The ratio is 0.0109261200583
