A group of students is investigating whether air resistance depends on the size of an object. The students throw two paper pieces each with the same force. One piece of paper is flat and the other is scrunched into a ball. The distance traveled by each paper piece is shown.

Experimental Observations
Student 1 Student 2 Student 3 Student 4
Distance traveled by flat paper 0.2 m 1.2 m 1.5 m 0.8 m
Distance traveled by scrunched paper 1.5 m 2.4 m 3 m 2 m

What was the test variable (independent variable) in this experiment?
Distance traveled by flat paper
The shape of the paper
Distance traveled by scrunched paper
The number of students

Answers

Answer 1

Answer:

The shape of the paper.

Explanation:

Flat Piece of Paper: Flat, (quite obvious haha) and not the easiest to throw

Scrunched up piece of paper: Easier to throw because it's simply in the shape of a ball, hence a ball being easy to throw. (:

Answer:

The Air moves to high to low system.

Explanation:

I think because of hot temperature it is hot.

The correct statement about pressure distribution due to uneven heating of the earth’s surface is the air moves from low to high-pressure systems. The correct option is B.

What is pressure distribution?

Pressure distribution is sometimes different in different areas. This happens due to the uneven warmth of the earth. The uneven heating causes a difference in temperature and cause different pressure in areas.

Where there is a low temperature, the air pressure is higher. During uneven heating, the air blows from low to high-pressure systems. The uneven heating of the earth is due to the reason that water heat slower than the land. This causes air to warm and expand and rise.

Thus, the correct option is B. The air moves from low to high-pressure systems.
