Explain the three properties of sound.
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
What happens when warm air rises? (5 points) (will give brain)
a
Global temperature decreases.
b
The movement creates a difference in air pressure.
c
Cool air rises with it.
d
It moves towards the poles.
Answer:
b)
movement creates a difference in air pressure.
as warm air rises up it creates a vaccum so due to that the pressure in that region decreases.
Answer:
B. The movement creates a difference in air pressure.
Explanation:
Please check my answers.
Which is a characteristic of an amorphous solid?
has a distinct melting point
becomes softer as temperature rises
particles arranged in a repeating pattern
made up of crystals
Answer:
4. Becomes softer as temperature rises
Explanation:
An amorphous solid is any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel. Solids and liquids are both forms of condensed matter; both are composed of atoms in close proximity to each other.
Based on the pattern of the P and S waves, what type of material is this planet made of?
(Tried to pick a subject but I could not find Science.)
Answer:
solid 6.
Explanation:
Observe the path taken by P and S waves in the model planet.
What are somethings about the Heliocentric model?
Answer:
Heliocentrism, a cosmological model in which the Sun is assumed to lie at or near a central point (e.g., of the solar system or of the universe) while the Earth and other bodies revolve around it.

Answer:
is it conduction because in that case it would be
Explanation:
the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

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.

Hope that helps :D brainliest PLEASE!
This question is about magnets and net force (I think.) Please no absurd answers!
Answer:
D
Explanation:
Ok this is what I think I think it's D because when two mangnets have a force upon one thing at the same time I don't think it would move
