Frequency is the vibration of noise and the vibration determines the pitch, which we depend on to be a pitch or frequency we can hear. If it's too high or too low our ears can't hear it
Answer:
1.1299 x 10^-8 second
Explanation:
Period = 1 / f = 1 / (8.85 * 10^7) = 1.1299 x 01^-8 sec
A movement which keeps the distal end of the body segment fixed in one location describes what type of kinetic chain movement is known as a <u>closed kinetic chain movement.</u>
<h3>What is a closed kinetic chain movement?</h3>
A closed kinetic chain movement is defined as that position where the most distal aspects of a particular extremity are fixed to the earth or another solid object.
In conclusion; a movement which keeps the distal end of the body segment fixed in one location describes what type of kinetic chain movement is known as a closed kinetic chain movement.

Answer:
<h2>76°</h2>
Explanation:
In projectile,
Maximum height = 
and range = 
u = velocity of the body
= angle of launch
g = acceleration due to gravity
If the range equals the maximum height in an ideal projectile launch on a horizontal plane, this means;
since 
The angle at which the range equals the maximum height in an ideal projectile launch on a horizontal plane is approximately 76°
