The climate near the equator is hot and dry, think of the Sahara desert. The climate near the north and south poles is very cold for almost the whole year.

One of the reasons for this is that as the earth orbits the sun the sun's rays are most intense for regions near the equator. Depending on the time of year, the sun's rays can be very weak near the poles, and if you are close enough to the poles there are days in deep winter when the sun does not even rise over the horizon!

When designing an engineering solution, certain criteria and constraints must be considered. Criteria are the features of the de

kondor19780726 [428]

Answer:

The criteria listed in order of importance are;

1) To be inflated in the event of a collision in order to protect the occupants of the front of the vehicle

2) To be able to withstand the load of the breaking force of the occupants in the front seat of the vehicle during a collision

3) To be relatively tough so as to resist being torn on impact with a sharp object

The constraints listed in order of importance are;

1) How is the model design able to sense a collision that requires the airbag to be inflated

2) The uncertainty of the load the airbag will withstand upon collision

3) The possible hazard that could be caused by the gas used to inflate the airbag

4) The usage/interaction tendency between the vehicle occupant and the airbag system

Explanation:

In order to produce an effective design, it is important to be able to foresee the possible deficiencies of an idea so as to be able to mitigate the problems before an actual incident happens.

How many protons electrons and neutrons respectively does 29 CS have

irakobra [83]

$55 \; \text{e}^{-}$ , $55 \; \text{p}^{+}$ , and $74 \; \text{n}^{0}$ - in case cesium-129 is what you were referring to.

Cesium has atomic number $55$ as seen on a modern periodic table. A cesium atom nucleus would thus contain an equal number of protons; in addition to that, a <em>neutral</em> atom of cesium would contain the same number of electrons in its electron cloud.

For a particular isotope,

$\text{Mass number} = \text{Number of protons per nuclei} + \text{Number of Neutrons per nuclei}$ .

This isotope of cesium has a mass number of $129$ and contains $55$ protons in each atomic nucleus. One cesium nuclei would therefore contain $129 - 55 = 74$ neutrons.

What is sodium bicarbonate an example of? a buffer an acid a liquid a base

ludmilkaskok [199]

Answer:

base

Explanation:

carbonic acid - H2CO3 - is a weak acid. Therefore, HCO3 itself is its conjugate base. The Na(sodium) ion is neutral.

This means that NaHCO3 is a base. (a weak one)

At a high elevation, there is little chance of... a) flooding b)lack of oxygen c) getting dizzy

labwork [276]

Answer:

A. flooding

Explanation:

At high elevations air becomes thinner so a person may not be receiving enough oxygen which can cause dizziness. Flooding typically happens at sea level.
