WILL GIVE 30 POINTS (by the way this is FLVS)

Question 1(Multiple Choice Worth 3 points)
(01.03 LC)

Which of these best describes a societal law?

A rule made by a government
A statement about how things act in the natural world
A statement which is always true under the same conditions
A statement which describes a specific relationship under given conditions
Question 2(Multiple Choice Worth 3 points)
(01.02 MC)

A student made the table shown to list some contact and non-contact forces.


Examples of Forces
Contact Forces Non-Contact Forces
The force applied by a magnet on an iron nail The force applied by an electromagnet on a wire
The force applied by a student on a door to open it The force applied by the planets on each other


Which statement best explains why the table is incorrect?
Magnetic force is a force acting at a distance.
The student applies a non-contact force on the door.
The electromagnet and wire have to be in contact to apply the force.
Gravitational force acts between planets only when they are in contact.
Question 3(Multiple Choice Worth 3 points)
(01.06 LC)

Which factor can decrease the kinetic energy of an object?

Increase in speed
Decrease in speed
Increase in temperature
Decrease in volume
Question 4(Multiple Choice Worth 3 points)
(01.02 MC)

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
Question 5(Multiple Choice Worth 3 points)
(01.01 LC)

Answer 1

societal law is A statement about how things act in the natural world. the wire and electro magnet need to touch in question 2. a decrease in spee decreases kinetic energy. the test variable was the distance traveled by the scrunched paper.
