The Coriolis effect influences _____. neither wind speed nor wind direction wind speed both wind speed and wind direction wind d

Alona [7]

Answer: The correct answer is "wind direction".

Explanation:

Coriolis effect: This is an apparent deflection of moving air or water caused by the rotation of the earth.

Currents are created by wind. Their directions are determined by Coriolis effect.

Currents are created by wind. The earth is in constant motion. It describes the rotation of the earth which steers winds and the surface current. The ocean surface currents are deflected by Coriolis effect.

The direction of the wind blows from north and south towards equator.

Therefore, the Coriolis effect influences wind direction.

A gas evolved during the fermentation of alcohol had a volume of 19.4 L at 17 °C and 746 mmHg. How many moles of gas were collec

AlexFokin [52]

Answer:- 0.800 moles of the gas were collected.

Solution:- Volume, temperature and pressure is given for the gas and asks to calculate the moles of the gas.

It is an ideal gas law based problem. Ideal gas law equation is used to solve this. The equation is:

PV=nRT

Since it asks to calculate the moles that is n, so let's rearrange this for n:

$n=\frac{PV}{RT}$
