Can you use Expo (dry eraser) markers to draw on your face? Will it do any damage to your skin?

Answers

I don't think ink pens and markers are the way to go if using them on skin, I'm not sure if they are safe, I wouldn't just to stay safe.

What are dry eraser?

The Environmental Protection Agency (EPA) states that the acute toxicity of n-propanol through cutaneous, oral, or inhalation modes of exposure is minimal. Like most other alcohols, n-butanol is flammable, corrosive, and generally regarded as toxic.

Although not harmful, acetone diacetyl is a well-known irritant. Additionally a potent cutaneous irritant, research on animals have shown that prolonged exposure to cresol can cause issues with the liver, kidneys, and blood.

Xylene can harm other organs and is neurotoxic. It poses a risk through ingestion, absorption through the skin, and contact with mucous membranes.

Therefore, I don't think ink pens and markers are the way to go if using them on skin, I'm not sure if they are safe, I wouldn't just to stay safe.

Which would be the best strategy for overcoming tobacco addiction

Answers

get different hobbies and start maybe going to the gym

The best strategy for overcoming tobacco addiction is to exercise, self control and just don't smoke. Eventually the urge to smoke will fade. If your self control isn't that good, you can use some other, less harmful form of nicotine (patches, chewing gum, or e-cigarettes), but if you do you will still be a nicotine addict even if you are no longer a tobacco addict.

In the second law of motion it is Mass X Acceleration. The ability to apply a change in velocity on a given object.

Answers

Newton's second law of motion is F = ma where force equals mass times acceleration.

What is Force?

A force is defined as a change in the momentum of an object that causes an object with mass to change its velocity which is to accelerate. Force can also be described as a push or pull. A force has both magnitude and direction which makes it a vector quantity.

Newton's second law of motion states that acceleration is what occurs when a force acts on a mass. For example, cycling is a good example of this law of motion where the bicycle has mass. The pushing force is exerted by the muscles of the legs on the pedals of the bicycle.

Thus, Newton's second law of motion is F = ma where force equals mass times acceleration.

Is hair mousse a solied liqued or a gas and why ?

Answers

It is a liquid that has a gas mixed with it to create the foam. If you shake the can you can hear and feel the contents inside. Think of it in terms of whipped cream it's a liquid until you shake the can combining the aerosol gas with the liquid inside.
hair mousse is like hair jel. its not something younwould expect it to be. it's somewhere around a liquid, but also a gas. it has both brands in a mixture to create somthing very hard to make and it holds hair in a perfect position to pose and stick. so the answer is probably liquid or gas. you're welcome.
