What defines a weapon of mass destruction?

A weapon of mass destruction is a nuclear, radiological, chemical, biological, or other device that is intended to harm a large number of people. The Department of Homeland Security works every day to prevent terrorists and other threat actors from using these weapons to harm Americans.

What are some examples of weapon of mass destruction?

Weapons of mass destruction can kill or eliminate large numbers of people in a short time. The main types are nuclear weapons (atomic weapons, radiation weapons), chemical weapons (such as poison gas) and biological weapons (natural toxins and pathogens, like the anthrax bacterium).

When were weapons of mass destruction used?

1937

What country has biological weapons?

What’s more powerful than a nuke?

But a hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts. The U.S. witnessed the magnitude of a hydrogen bomb when it tested one within the country in 1954, the New York Times reported.

Which is the most dangerous star?

Eta Carinae: One of the most dangerous stars in our galaxy, Eta Carinae—the central luminary of the Carina Nebula—is also one of the most massive, with the primary star estimated to be 120-250 solar masses.

Will a supernova destroy Earth 2022?

Although they would be spectacular to look at, were these “predictable” supernovae to occur, they are thought to have little potential to affect Earth. It is estimated that a Type II supernova closer than eight parsecs (26 light-years) would destroy more than half of the Earth’s ozone layer.

Can a supernova destroy a galaxy?

Supernovas are created during the last moments of a star’s life. These gigantic explosions can wipe out galaxies and the planets inside them.

What happens when a star goes supernova?

It’s a balance of gravity pushing in on the star and heat and pressure pushing outward from the star’s core. When a massive star runs out of fuel, it cools off. This causes the pressure to drop. The collapse happens so quickly that it creates enormous shock waves that cause the outer part of the star to explode!

Is supernova a dying star?

Bottom line: A supernova is the cataclysmic explosion of a star at the end of its life. Supernova explosions come in different types, but all can emit more energy in a few seconds than our sun over its entire lifetime. Some supernovae outshine an entire galaxy for a brief period.

Will Betelgeuse go supernova in our lifetime?

But because Betelgeuse is so massive and burns through its fuel so quickly, it’s already in the final life stage of a red supergiant. Someday in the not too distant future, the star won’t be able to support its own weight — it will collapse in on itself and rebound in a supernova.

What defines a weapon of mass destruction?

What is the most common type of weapon of mass destruction?

Chemical and Biological Weapons Historically, chemical weapons have been the most widely used and proliferated type of WMD, but they receive far less attention than do biological and nuclear weapons (NTI, 2015b,e).

What are weapons of mass destruction quizlet?

Any weapon designed to deliberately contaminate or poison an area with radiological sources; normally considered “Weapons of Mass Destruction ” (WMDs).

What is an example of a weapon of mass destruction?

Terrorism and Homeland Security A weapon of mass destruction (WMD) is something capable of inflicting mass casualties and/or destroying or rendering high-value assets as useless. Although chemical, biological, nuclear, and radiological weapons often serve as examples of WMD, many things can be used as a WMD.

Is a gun a weapon of mass destruction?

Chemical weapons expert Gert G. Harigel considers only nuclear weapons true weapons of mass destruction, because “only nuclear weapons are completely indiscriminate by their explosive power, heat radiation and radioactivity, and only they should therefore be called a weapon of mass destruction”.

What is the easiest WMD to obtain?

Chemical warfare agents

What are the three types of Wmds?

There are three types of WMD’s: Biological, Chemical, and Nuclear. While there is only one recorded WMD attack by the Taliban, there is a long history of such methods being used.

Is chlorine a choking agent?

Chlorine gas was first used as a chemical weapon on a large-scale during World War 1 in the Second Battle of Ypres and is considered a choking agent.

Is ammonia less dense than water?

This way, we can see how powerful an effect the hydrogen bond has on keeping water molecules together — while ammonia has a density of 0.73 kg/m³ and hydrogen sulfide has a density of 1.36 kg/m³, water has a whopping density of 1,000 kg/m³.

Is oxygen less dense than water?

Water is heavier the O2 and H2 gases because the H20 molecule’s particular electron configuration cause it to be a liquid between 0 C and 100 C at 1 atmosphere of pressure. Liquid water is much denser that gaseous oxygen and oxygen with a density of about 1000 Kg per cubic meter.

What liquids are more dense than solids?

Mercury, a metallic element that is a liquid at room temperature, is denser than many solids.

How much nitrogen is in household ammonia?

Ammonia is 82.35% nitrogen by weight.

Can ammonia kill a tree?

Most ammonia is derived from the microbial breakdown of urea from humans and domestic animals, or from inadvertent volatile losses during the use of nitrogen fertilizers. Ammonia has a wide range of impacts on the natural environment. And too much nitrogen can be toxic to trees and even kill them.

Do ferns like ammonia?

Ammonia has lots of nitrogen in it and plants do use nitrogen. However, there is more than enough nitrogen in the potting soil. Don’t use ammonia on your plants. Boston ferns must be close to a window where they get a few hours of direct sun and indirect sun for the rest of the day.

Will ammonia kill weeds?

Yes- ammonia does kill weeds. It’s important to spray all parts of the undesirable plants, including the soil around it, so that some of the ammonia can seep into the roots and kill them off too.

What kills weeds permanently?

Yes, vinegar does kill weeds permanently and is a viable alternative to synthetic chemicals. Distilled, white, and malt vinegar all work well to stop weed growth.

How do you mix ammonia to kill weeds?

How to Use Ammonia to Kill Weeds

Dilute the ammonia. Mix two-thirds parts ammonia with one-third part water.
Warning. Do not mix ammonia with any other chemical because it may produce a toxic gas. Wear gloves whenever handling a chemical.

Does Dawn dishwashing liquid kill weeds?

Dish soap alone cannot kill weeds — but it can help. Environmentally conscious home gardeners often turn to organic weed killers to reduce toxins in the soil and water. One place they can go is to the kitchen. Dish soap, along with vinegar and salt, can kill weeds.

What do you mix with Epsom salt to kill weeds?

Epsom salt serves as a weedkiller in two ways. One mixture is a few tablespoons of Epsom salts mixed with warm water. The other mixture calls for 1 tbsp. of Epsom salt, 1 gallon of vinegar and a small amount of dish soap.

Does vinegar Epsom salt and Dawn dish soap really kill weeds?

It’s a “safe, natural weed-killer” made from mixing vinegar, Epsom salts, and Dawn liquid detergent. They kill the top growth, but if the weed is perennial or has an extensive root system (like dandelion, poison ivy, or brambles), they grow right back from the roots.

Does table salt kill weeds?

Table Salt – Using salt to kill weeds is a common do-it-yourself solution. When salt is absorbed by plant root systems, it disrupts the water balance and causes the weed to eventually wilt and die. But salt by itself doesn’t make a very effective weed killer.
