F(of spring)=230x=ma=3.5(5)=17.5=230x; x=0.07m.
The pressure at 100 meters below the surface of sea water with a density of 1150kg is 145.96 psi.
Answer:
<h3>
</h3>
Explanation:
Given,
F = 100 , M = 25
Now, let's find the value of A
plug the values
⇒
Swap the sides of the equation
⇒
Divide both sides of the equation by 25
⇒
Calculate
⇒

Speed of sound through a medium depends on
● temperature
● density of medium
● speed of wind
● humidy
● moisture
Speed of sound increases with increase in temperature. Because when temperature increases the molecules get higher energy and they vibrate quickly. Due to this vibration sound waves can travel fastly.
