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.

The momentum of an object is determined to be 7.2 × 10-3 kg⋅m/s. Express this quantity as provided or use any equivalent unit. (

slavikrds [6]

Answer:

Momentum, p = 7.2 g-m/s

Explanation:

It is given that,

The momentum of an object is $p=7.2\times 10^{-3}\ kg-m/s$

We need to express momentum in any equivalent units. There can be many solutions of this problem. Some of the units of mass are gram, milligram etc. units of length are meters, mm etc.

Since, 1 kg = 1000 gram

So, $p=7.2\times 10^{-3}\times 10^3\ g-m/s$

Therefore, the momentum of the object is 7.2 g-m/s. Hence, this is the required solution.

Match each term to the best description

Ronch [10]

Answer:

Coefficient of friction = Magnitude depends on the interacting materials

Friction = A force that acts parallel to the surface.

kinetic friction = A force that is constant regardless of the applied force

Normal = A force that acts perpendicular to the surface

Static friction = A force that increases as applied force increases up to some maximum value

Explanation:

Let's define all the forces, and then let's solve the problem.

Normal force:

When an object rests on some place (like a book on the table) the force that causes the book to not fall through the table is called the normal force, which is usually equal to the weight of the object and acts perpendicular to the surface where the object is resting.

Friction force.

When an object moves (or tries to move) parallel to a surface, such that the object is in contact with that surface, there appears a force that opposes to the movement (the force is parallel to the surface, and in the opposite direction to the movement).

And this force can be written as:

F = -N*μ

Where μ is the coefficient of friction and N is the normal force.

If the object is not moving yet (but there is applied a force that would move the object) the coefficient is called the coefficient of static friction which increases in a given range, until it can't keep increasing and the object starts to move, while if the object is moving, the coefficient is called the coefficient of kinetic friction and it is constant, where usually the first one is larger than the second, and these coefficients depend on both materials, the surface one and the object one.

Then we have two friction forces, one called the kinetic friction and the other called the static friction.

Then:

Coefficient of friction = Magnitude depends on the interacting materials

Friction = A force that acts parallel to the surface.

kinetic friction = A force that is constant regardless of the applied force

Normal = A force that acts perpendicular to the surface

Static friction = A force that increases as applied force increases up to some maximum value

Hello,

The answer is A) a mixture. An element as defined as a pure substance, that cannot be broken down and most are typically naturally occurring. A compound occurs in chemical bonding. A substance is either a pure element or compound.

What would be a disadvantage of asexual reproduction for an organism

Tems11 [23]

A negative mutation can make asexually produced organisms susceptible to disease and can destroy large numbers of offspring. Some methods of asexual reproduction produce offspring that are close together and compete for food and space. Unfavourable conditions such as extreme temperatures can wipe out entire colonies.
