1. What is the cause of the Coriolis effect?

2 answers:

8 0

1.) The answer would be D.Earth's rotation, since the rotation makes the air and wind direction appear to be going in a different direction than it really is due to the earth rotating (this deflects the winds)
2.) The answer would be C.Relative Humidity, since this is ratio of water vapor in the air to a given area, while humidity is simply the amount of water vapor in the air in general.
3.) B. Warm Front, since cold fronts usually bring stormy weather, while the weather conditions brought by a warm front are typically more mild.
4.) For this one, I'm not sure, but I'm pretty sure the closest answer would be C.4. The way I have learned this is that there have been 5 major ice ages, however the choice isn't on there.

How do sand dunes move?<br> Use the terms leeward and windward in your explanation.

gogolik [260]

As the sand mound grows, the point of maximum sand deposition on the leeward face moves closer to the summit, causing a steepening of the leeward face relative to the windward face. The steepening and growing dune now forces wind out over the top of the dune rather than down the leeward face.

What is the concentration of H+ ions at a pH = 2?

kari74 [83]

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

In Step 5, you will calculate H+/OH– ratios for more extreme pH solutions. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide for a solution at a pH = 2. Then divide the H+ concentration by the OH– concentration. Record these concentrations and ratio in Table C.

What is the concentration of H+ ions at a pH = 2?

What is the concentration of OH– ions at a pH = 2?

What is the ratio of H+ ions to OH– ions at a pH = 2?

Those are your correct answers on edg2020!

I LITERALLY spent 40 MINUTES trying to figure out this question, so please, use my VERY CORRECT answers!

<em>I hope this helps!</em>

Freezing point and boiling point of a substance P is -220 0 c and – 185 0c. A t which of the following range of the temperatures

Firlakuza [10]

Answer:

Between -195°C to -215°C

Explanation:

We begin from this data:

P under -220°C will be solid, because -220°C is the freezing point.

Above -220°C, P will be at liquid state.

Then -185°C is the boling point, so above that temperature we have P as a gas.

Between -175°C to -210°C

Above -185°C we said that P is gas, so at -175°C P is not liquid. This state is F.

Between – 190°C to -225°C

At -190°C, we can have P as liquid, but -225°C is under -220°C, where P changes from liquid to solid. Then, this state is also F.

Between -200°C to -160°C

Above -185°C we said that P is gas, so at -160°C P is not liquid. This state is also F. The same, as the first situation.

Between -195°C to -215°C

-195°C is a lower temperature than -185°C. P is still liquid, we did not get the boiling point yet. -215°C is higher than -220°C, P is also liquid. There are still 5°C until P completely freezes. <em>This is the correct choice.</em>
