Answer: Clouds are evaporated sea water. You should be asking "Why does the gravity on Earth pull us down and not evaporated water.

Answer:

Because of their mass

Explanation:

Clouds are made of water right ? so you are asking why they don't fall down if air is lighter than water .

The two biggest reasons the clouds stay in the sky are

1. Small Drops

2. Wind

Small drops of water fall more slowly than big drops, as the drops of the clouds fall thought the air, the air pushes back to them, because Small drops has less mass than large drops, clouds can only contain small drops of water.

(a) How much gravitational potential energy (relative to the ground on which it is built) is stored in an Egyptian pyramid, give
Rom4ik [11]

Answer:

2.66832\times10^{12}

Or

2,668,320,000

Explanation:

Potential energy is given as the product of mass, acceleration due to gravity and height.

PE=mgh

Where m is the mass of pyramid, g is acceleration due to gravity and h is height at any point.

In reference to the earth, we substitute h for 34.0 m and g with 9.81 m/s2 then taking m as 8000000000 kg we get that

PE=mgh=8000000*9.81*34.0=2,668,320,000 J

In scientific notafion, this is expressed as 2.66832\times10^{12}

An object moves in simple harmonic motion described by the equation d equals one fifth sine 2 t where t is measured in seconds a
tensa zangetsu [6.8K]

Answer:

The maximum​ displacement, the​ frequency, and the time required for one cycle are 1/5 inch, 1/π Hz and π sec.

Explanation:

Given that,

The equation of simple harmonic motion

d = \dfrac{1}{5}\sin 2t.....(I)

We need to calculate the maximum amplitude

Using equation of simple harmonic motion

y = a \sin\omega t

Where, a = amplitude

\omega =frequency

t = time

On comparing equation (I) and general equation

The amplitude is a maximum displacement traveled by a wave.

a = \dfrac{1}{5}

So, the maximum displacement is

d= \dfrac{1}{5}\ inch

We need to calculate the frequency

\omega=2\pi f

f = \dfrac{1}{\pi}\ Hz

We need to calculate the time required for one cycle

t =\dfrac{1}{f}

t =\pi\ sec

Hence, The maximum​ displacement, the​ frequency, and the time required for one cycle are 1/5 inch, 1/π\ Hz and π\ sec.

Start with a puddle on a sunny day. How might water move through the water cycle and eventually fall as rain
Naddik [55]
The puddle would warm up then begin to evaporate and then the gas could create a cloud the condensate and then make rain again to create another puddle then it happens all over again
