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


Examples of Forces
Contact Forces Non-Contact Forces
The force exerted by a stretched spring The force applied by Earth and sun on each other
The electrical force exerted by a positive charge on a negative charge Magnetic attraction between two magnets


Which statement best explains why the table is incorrect?
Spring force is a force acting at a distance.
Electrical force is not a contact force.
Gravitational force can act between planets and sun only when they are in contact.
Magnetic attraction is a contact force

Speed force acting at a distance

1st Law - Law of Inertia 2nd Law - Law of Force and Acceleration 3rd Law - Law of Action-Reaction An eagle soars through the air by pressing its wings downward. The air, in turn, propels the bird upward.

Mintu wants to increase the heat transfer between a metal iron and another piece of metal he wants to shape. He decides to increase the time the two metals are in contact, use a larger metal iron, and use a new metal material with a higher specific heat.

Where is Mintu's error?

Mintu should have decreased the size of the metal iron.
Mintu should have decreased the time he touches the two metals.
Mintu should have chosen a material with a lower specific heat.
Mintu should have chosen a material the same temperature as the iron.

Look at the image below and answer..
a. All matter and energy were contained inside the small point.
b. Matter and energy came from dark areas of the universe and were attracted to the small point.
c. Matter and energy fell into the small point the same way a black hole attracts matter and energy.
d. Matter was condensed into a single point until energy was attracted to the matter from dark areas of the universe.

Explain the relationship between wavelength and frequency in the electromagnetic spectrum.

View the photo below, read the passage, and answer the question.



The arcs in the photo are background galaxies that were distorted and magnified by a giant cluster of dark matter. As the light leaves its source, the gravity of the cluster of dark matter bends that light, creating the swoops in the image above.

This passage best supports which conclusion about dark matter?

a. Dark matter does not give off light, but scientists can see the reflection in stars around it
b. Dark matter is created from clouds of dust and gas scattered throughout the universe
c. Dark matter has a significant impact on the stellar life cycle
d. Dark matter does not give off light, so it can only be detected by observing the effects of gravity on visible objects nearby

The distance versus time graph for Object A and Object B are shown.

{IMAGE} A graph titles Distance vs Time. A curved line is drawn through point 10 on y axis and this line is labeled Object A. The graph for Object B is a straight slanting line passing through the origin

Which statement best describes the motion of Object A and Object B?

Both objects move with variable speed.
Both objects move with constant speed.
Object A moves with constant speed and Object B moves with variable speed.
Object A moves with variable speed and Object B moves with constant speed.

Drag each label to the correct location on the image.

Jessica is visiting a park with her mother. Jessica sits on a swing. Her mother pulls the swing to a height of 3 meters above the ground and lets it go. The image shows Jessica at three positions on the swing. Jessica‘s mass is 44 kilograms and the maximum velocity of the swing is 5 meters/second. What’s the energy she has at each position shown? Ignore friction and air resistance.

Reasoning = EXPLAIN each piece of evidence and HOW it supports your claim. Make sure this is thorough and IN YOUR OWN WORDS.
