Answer:
Currents are physical occurrences or factors that put motion into oceans, making them move back and forth.
Such factors include but may exceed the following:
- Wind
- Variation in water mass densities (this is caused by alterations in temperature and salinity levels)
- Gravity
- Earthquakes or storms
When there is movement in ocean currents, heat, nutrients, water oxygen levels are also affected.

Answer:
A. She can run the same distance in a shorter amount of time.
Explanation:
Speed can be computed with the formula:

Where:
v = speed
d = distance
t = time
So if you look at the formula, distance there tells you how far an object has traveled, and the time tells us how long it took to cover that distance. As you can see, speed and time are <u>inversely proportional. </u>This means that as one goes up, the other goes down. So if we reduce time travelling a certain distance, the speed increases.
Answer:
<em>Hydrogen bonding</em>
Explanation:
<em>Acetone major species present when dissolved in water is called hydrogen boding. these occurs when, the acetone and water as the oxygen of acetone's cabonyl bond with the O-H of water.</em>
<em>Such presence of hydrogen bonding would helps the ability of molecules of two types to be miscible together</em>
Answer: Molarity of the solution is
and water is the solvent.
Explanation:
Given: Mass of solute = 26.8 g
Volume = 4.00 L
Now, moles of copper (II) chloride (molar mass = 134.45 g/mol) are calculated as follows.

Molarity is the number of moles of a substance divided by volume of solution in liter.
Therefore, molarity of given solution is calculated as follows.

Solvent is defined as a component which is present in higher amount in a solution. Generally, a solvent is present in liquid state but it can also be a solid or gas.
In the given solution, copper (II) chloride is dissolved in water so copper (II) chloride is the solute and water is the solvent.
Thus, we can conclude that molarity of the solution is
and water is the solvent.
