Answer:

Because a fire requires oxygen from the atmosphere to burn.

Explanation:

An open system is when the fire needs the air to burn and also allow the smoke to escape or be released without the need to be "guided" or drive along a made path such as a chimney or through a stack. This process ensures that no smoke is retained or confined in a closed space.

Burning of wood involves a great deal of smoke being released by the burnt wood. So, for the smoke to be released freely, the act of burning in an open space facilitates easier means of dispersing the smoke and not be harmful to the persons/ living things nearby. If wood burning is done in a closed space, it will only suffocate the ones inside the room, making it difficult for fresh air to facilitate easy burning and will require a chimney for the smoke to be released.

Thus, <u>a wood-burning fireplace represents an open system as fire requires oxygen from the atmosphere to burn and also disperse the smoke easily without the need for a chimney or a stack. </u>

What exactly is meant by a "freely falling" object? What exactly is meant by a "freely falling" object? An object in free fall f
beks73 [17]

Answer:An object in free fall falls under gravity alone with no friction

Explanation:

Gravity in physics is explained as that force which pulls us down towards the center of the earth; helps us not to float .

What does friction mean?

Friction is a force that acts in an opposite direction to that of the object's movement .

So if the object is not pushed in an opposite direction by any force it will fall freely , it will fall and roll down or it will fall and continue to move in its direction for example an orange falling from a tree ( pulled by gravity) without any force opposing it's movement it will fall continue sliding or rolling down unless there is something hindering it's movement.

Another example is, if you were running and reach a corner and decided to halt your shoes will act as a friction to help you stop immediately.

However if you run in the rain and the road is slippery or there are puddles on the road, when you want to slow down or stop the friction will be less.

The less friction means the harder it is to halt which also occurs when you drive during rain weather .

It is hard to stop the car in time due to less friction on the tires which is reduced by the slippery wet road .

An object will fall and slide down unless some opposing force is there to oppose that movement , that is what free fall means.
