Carpet burn - where you fall super fast on carpet, and the friction gives you a burn

Driving a car - friction may slow it down

Pulling/pushing an object on the floor - friction will make it harder to pull/push

Playing air hockey on the floor - friction will stop the puck

Pushing a ball down a road - friction will make the ball stop at a faster rate

Use newton's law to explain the vertical acceleration of a projectile

NISA [10]

Answer:

Explained below

Explanation:

Newton's first law of motion: This law states that an object will remain at rest or continue in constant motion except it's acted upon by an external force. In projectile motion, the horizontal component of velocity will remain unchanged because we ignore air resistance since no force is acting in that horizontal direction.

Newton's second law of motion: This law states that force is the product of mass and acceleration. In projectile the force acts downwards, thus f = mg.

But g = a since internal forces will cancel out.

Thus, F = ma

How does the size of arctic foxes ears help to keep them warm in a cold environment

DochEvi [55]

artic foxes have thick white fur to keep them warm and also for camouflage in the snow they have small ears to keep the snow out of their ears so that they can hear better they also have thick fur lining and a thick pad on their feet this stops the paws from getting cold and they have short legs so then the body weight can be spread making it easier for the animal to not sink in the snow in the summer the artic fox turns brown to help make the fox invisible when people are hunting in the long grass

describe the charge, mass and the location of each subatomic particle and the role each plays in determining the properties of a

Harrizon [31]

Explanation :

An atom is a smallest particle of matter. An atom consists of protons, neutrons and electrons. These are three subatomic particles.

Protons are positively charged species while neutrons are negatively charged species. Electrons revolves around an atom.

Charge :

The charge of an electron is negative or $-1.6\times 10^{-19} \ C$

The charge of proton is +e or $1.6\times 10^{-19} \ C$

Neutron has no charge.

Mass :

Atomic mass of electron is $9.1\times10^{-31}\ Kg$

Atomic mass of proton is $1.67\times10^{-27}\ Kg$

Atomic mass of neutron is $1.67\times10^{-27}\ Kg$

Both protons and neutrons are located inside the nucleus at the center.

Charge, atomic mass and location determines the properties of an atom. Atomic mass tells about the number of protons and neutrons inside an atom. Electric charge tells us the number of electrons gain or lost.

How is nuclear fusion different from an explosion from chemical reactions

ELEN [110]

Answer:The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one.

Explanation:Protons and neutrons make up a nucleus, which is the foundation of nuclear science.
