The correct answer is by roughly one million times.

Any product of the condensation of atmospheric water vapor, which falls under gravity is known as precipitation. The main forms of precipitation are rain, drizzle, snow, sleet, and others.

All the precipitation give rise to clouds and the clouds are produced when water vapor in the atmosphere condenses and cools. With the condensation of water vapor, the formation of water droplets takes place, and if the formation of clouds takes place within or is moved into the part of the atmosphere, which is below freezing then the droplets turn into ice crystals.

In order to form precipitation, the cloud droplets must grow in volume by roughly one million times.

PtichkaEL [24]

Answer:

In most materials, as heat energy is absorbed, the density decreases. IF a certain object is heated, it might appear bigger than usual because it expands as the molecules inside moves faster than usual. However the mass of it stays the same while the density decreases.

If we double the frequency of a system undergoing simple harmonic motion, which of the following statements about that system ar

AnnyKZ [126]

Answer:

a. The angular frequency is doubled.

e. The period is reduced to one-half of what it was.

Explanation:

Angular frequency is given as;

ω = 2πf

$\frac{\omega _1}{f_1} = \frac{\omega _2}{f_2}$

when the frequency is doubled

$\frac{\omega _1}{f_1} = \frac{\omega _2}{(2f_1)} \\\\\omega _1 = \frac{\omega _2}{2}\\\\\omega _2 = 2\omega _1$

Thus, the angular frequency will be doubled.

Amplitude in simple harmonic motion is the maximum displacement.

Frequency is related to period in simple harmonic motion as given in the equation below;

$f = \frac{1}{T} \\\\f_1T_1= f_2T_2\\\\T_2 = \frac{f_1T_1}{f_2}$

when the frequency is doubled;

$T_2 = \frac{f_1T_1}{2f_1} \\\\T_2 = \frac{T_1}{2}$

Thus, the period will be reduced to one-half of what it was.

what is the maximum distance we can shoot a dart,from ground level provided our toy dart gun gives a maximum initial velocity of

mestny [16]

Answer:

R = v^2 sin 2 theta / g

The range provides the distance a projectile can travel

R(max) = v^2 / g if theta = 45 deg

R = 2.7^2 / 9.8 = .74 m

The velocity of a car decreases from 28m/s to 20m/s in a time of 4 seconds. what is the average acceleration of the car in this

Olin [163]

The average acceleration of the car in this process is -2 m/s²

<h3>What is Acceleration ?</h3>

Acceleration can be defined as change in velocity per time taken. It is a vector quantity. That is, it has both the magnitude and direction. It is measured in m/s²

Given that a velocity of a car decreases from 28m/s to 20m/s in a time of 4 seconds. Then,

Initial velocity u = 28 m/s

Final velocity v = 20 m/s

Time t = 4 s

Acceleration a = ?

From the definition of acceleration,

a = Δv / t

a = ( 20 - 28 ) / 4

a = -8 / 4

a = - 2 m/s²

Therefore, the average acceleration of the car in this process is -2 m/s² which mean that the car is decelerating.
