The higher the sea surface temperature, the faster the warm, moist air rises into the atmosphere. This updraft creates a donut shaped vortex that is rising in the middle and going downward on the sides. The more moisture in the air (humidity), the stronger the vortex will become as the moisture rises through convective currents, cools, and falls through convective currents. This eventually causes rotation of the storm mass and you get a tropical cyclone. So, the high sea surface temperatures and humidity are actually the engine that forms a hurricane and causes it to increase in strength.
High level horizontal winds can prevent a hurricane from forming. These are called shear winds and they literally blow the top of the cyclone off, preventing it from forming properly.
Answer:
ΔE / E = ΔV / V + Δd / d
Explanation:
The electric field and voltage are related by the expression
E = V / d
The uncertainty of the field is
ΔE / E = ΔV / V + Δd / d
We see that the uncertainty of the field must be added the uncertainty of the distance that in the measure of the different potential has no effect.
The only case in which the uncertainties are equal is if the distance measurement has no uncertainty, or the separation of very high
Answer:
S.H.M:- If the acceleration of the vibrating body directly varies with the displacement of the body from the mean position and always directed to the mean position, the motion of that body is called simple harmonic motion.
Ex:- (i) The motion of a pendulum is an S.H.M.
(ii) The motion of vibrating mass attached to a spring is an S.H.M.
<u>P.E (Potential Energy) = 33868.8 J</u>
<u>Explanation:</u>
The formula to calculate Potential energy is:
PE = mgh
where PE = potential energy
m = mass of an object
g = acceleration due to gravity
h = height of the object
Here, m = 64 kg
g = 9.8 
h = 54 m
So, substituting the values in the formula:
PE = mgh
= 64 × 9.8 × 54
= <u> 33868.8 J</u>
