The first is that the object moves. The second is that a force must act on the object in the direction the object moves.

Convert the number from scientific into standard notation: 5.9 x 10-2
guapka [62]
Move the decimal point to:
Left : (if the exponent of ten is a negative number -) ... OUR CASE HERE (-2)
or to
Right : (if the exponent is positive +).

You should move the point as many times as the exponent indicates.
Do not write the power of ten anymore.

So, standard form is:
Two points to the left {Exponent of Ten is Negative (-2)}
0.059 ... (without the 10)

A cylinder at left with balls evenly spaced throughout the cylinder has an arrow leading to a cylinder at right cylinder with ba
pentagon [3]

The change of state as depicted by the model is condensation.

<h3>What is Condensation?</h3>

The process by which the water vapors get converted into liquid droplets to get settled on a cold surface is known as condensation.

As per the given problem, the cylinder in the left has the balls evenly spaced throughout and the right cylinder has the balls in the form of layers at its bottom.

So, this clearly reflects that the comparing both the balls in both cylinders, the right cylinder consists of the balls undergone through the process of condensation.

This is because,

During condensation, the vapor molecules get converted into liquid.

And in the left cylinder, the balls evenly spaced have more intermolecular distance which designates the gaseous molecules.

While in the right cylinder, the layered form of gas shows that the conversion occurred to some state of molecules, having less intermolecular space.

And liquid has less intermolecular space than gas.

Thus, we can conclude that the change of state as depicted by the model is condensation.

If there is no friction in a rollercoaster is the speed the same throughout?
andrey2020 [161]
If there is no friction, the roller coaster would keep moving forever but a constant velocity. The only way it would accelerate is if there was a force continually pushing on it.

Giant cave systems have formed through the reaction of acids with the BLANK that make up limestone
Ivenika [448]
<h3><u>Answer;</u></h3>

Carbonates

<h3><u>Explanation;</u></h3>
  • Giant cave systems have formed through the reaction of acids with carbonates the that make up limestone.
  • <em><u>Caves are formed as a result of dissolution of limestone, through a type of chemical weathering known as carbonation. This happens when rainwater picks up carbon dioxide from the air and as it percolates through the soil, resulting to the formation of weak carbonic acid. </u></em>
  • The weak carbonic acid formed then slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.
  • Largest caves are formed at a place where the water flows onto the limestone  from an adjacent impermeable Portishead formation and Avon Group mudstones.
