If the power is out long enough even the city folks will run out of water. Many homes are all electric, so as soon at the lights are out they have no heat, no hot water and they can't cook. ... If the power is out, gas stations can't pump gas. Once generators run out of gas, those people will be in the dark too.

Answer:

Living with no electricity might not be as easy as you may think and you not realise how many items in your home rely on it to function.

Electrically managed technologies supply us with many things, such as heat, food, water, transport, energy, entertainment and communication.

Electricity allows us to power the technology we use every day.

If you plan on trying to live without electricity, you will no longer be able to turn on the central heating in your home, use the toilet, preserve food in your fridge/freezer or have clean running water.

Despite surviving thousands of years without it before, we have come to depend on it to complete our everyday tasks and have built our lives around it.

The Internet goes down.

How many half-lives would something have gone through if you had 75% daughter product and 25% parent?

levacccp [35]

Answer:

Two Half-lives

Explanation:

Let number of Parent nuclei Initially present be X,

Then, finally $\frac{X}{4}$ Parent nuclei Will remain with $\frac{3X}{4}$ daughter nuclei.

In one half- life , parent nuclei becomes half of initial.

So, starting with X parent nuclei,

After one half-life, it will degrade to $\frac{X}{2}$ .

After another half life , Parent nuclei will become half of $\frac{X}{2}$

Which is equal to $\frac{X}{4}$ .

So, Parent nuclei have to go through Two half-lives.

An element A combines with element B. The electrons are transferred from the atom A to the atom B. .

Sloan [31]

(a) The nature of bond between A and B is an ionic bond.

(b) The two main properties of the ionic compounds are:

Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break.
The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions.

<h3>What is an ionic compound?</h3>

Ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions.

An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation—a positively charged ion.

In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution.

The car wit fastest acceleration is the tempest. it has an acceleration of 6.1 m/s. suppose the car accelerates from rest to a f

ziro4ka [17]

Given:

Initial velocity (v1) = 0 m/s

Final velocity (v2) = 30 m/s

Acceleration (a) = 6.1 m/s2

To determine:

The time (t) taken to reach the final speed

Explanation:

Use the relation:

Acceleration (a) = [final velocity(v2) - initial velocity (v1)]/time (t)

t = (v2-v1)/a = 30-0/6.1 = 4.92 s

Ans: Time taken is around 4.9 s

Help me out will ya?

vampirchik [111]

Answer:

Option C) the chance of water-borne diseases.

Explanation:

When a flood happens, water will lpotentially get contaminated by several causes which include the overflow of untreated wastewater, the decomposition of the carcasses of animals and people, and the chemical contamination from industries.

In general, biochemical and chemical hazards are present in the water, after a flood, which means that the authorities and population should take extreme care for the use and intake of water: chemical treatment (use of chlorine), boil water. As usual, children and the elderly are the most at risk in those conditions.
