Answer:

Because in the event of a rear collision, the cervical spine, in the neck region, can project quickly forward and then backwards, causing serious problems if the headrest is not adjusted.

Explanation:

Head support is not widely remembered when talking about driving safety, but its use can prevent serious injuries in the event of an accident. The correct use of the headrest is as important as the seat belt and its usefulness is even greater in cases of rear impact. In rear collisions, it is common to report the whip effect on passengers of the vehicle that was hit. It gets its name because the impact of one vehicle on the rear of another projects the occupants of the car ahead ahead. With the crash, the seat belt holds people's bodies - but not the neck and head. With this, the cervical spine, in the neck region, can quickly project forward and, soon after, backward. Sort of like a rubber band or whip - hence the name.

One of the ways to prevent cervical spine injuries is to adjust the seat headrest correctly. By correctly adjusting the device, in the event of a rear collision, the backrest prevents excessive movement of the neck and head.

Answer:

Disability insurance is financial protection for your most valuable asset — the ability to work and earn an income. So why is it so commonly overlooked and misunderstood?

Homeowners insurance protects where you live. Car insurance protects what you drive. Health insurance protects your well-being.

But what protects your ability to work and earn an income? After all, that's what allows you to pay for all of the above.

To protect yourself against the risk of losing your paycheck due to injury or illness, there's disability insurance. In this article, we cover everything you need to know about this important, yet often overlooked type of insurance for your income.

Disability insurance definition

Disability insurance is a type of coverage that replaces a portion of your monthly income if injury or illness prevents you from working. It provides financial security for you and any loved ones who may depend on your most valuable asset — your ability to earn a paycheck. You may also hear disability insurance referred to as disability income insurance or income protection.

Choose all that apply. Solids, liquids, and gases can be distinguished by their:molecular weight shape temperature kinetic energ
vesna_86 [32]
So, we have:
- molecular weight
- shape
- temperature
- kinetic energy
- mass
- density

Let's rule out the different options.
- molecular weight: Say you have a molecule of H2O. H2O can be a solid, liquid, or gas, but its molecular weight never changes throughout (It's still the same molecule, no matter what phase it is in). We can rule this out.

- shape: Let's pretend we have three identical closed containers, and we fill each one halfway with water, blocks of ice cubes, and water vapor. In the container with water, you will see that the water takes the shape of the container, but doesn't fill the entire container up. The ice cubes will stay ice cubes, assuming they don't melt, so they don't take the shape of the container. The vapor will fill up the entire container. Since all three are different, I would say yes, this could be a distinguishable feature.

- temperature: In general, I would say no, because every element/molecule has different boiling points and different vaporization points. So if you have a liquid at 5°C, you could also have a different element in solid form at 5°C. But if you're comparing a single type of molecule, it would have a boiling point and a vaporization point, so you <em>would</em> be able to tell between them.

- kinetic energy: Kinetic energy refers to how much movement there is in respect to each molecule. In solids, the molecules are packed tightly together and can't move very much, so they have lower kinetic energy. In liquids, they are less packed, but still restricted. And in gases, they can fly freely, so they will have much more kinetic energy than liquids or solids. This one's a yes.

- mass: No matter what form, there are still the same amount of molecules, and each molecule has the same mass as before. It won't change.

- density: Since the molecules are more spread out in gases, it will be less dense. Liquids will be more dense, and solids will have the greatest density. So, yes.

Conclusion: shape, kinetic energy, density, (and temperature if it's talking about a single type of molecule)

A metal is found that has a mass of 27g and will displace 6mL of water. Calculate its density and identify the metal.
melisa1 [442]

The density of metal = 4.5 g/ml, and the metal = Titanium

<h3>Further explanation  </h3>

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

Density formula:  

\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}

ρ = density  

m = mass  

v = volume  

mass of metal=27 g

volume = 6 ml

The density :

\tt \rho=\dfrac{27}{6}\\\\\rho=4.5~g/ml

The metal with a density of 4.5 g/ml is Titanium
