Answer:
Explanation:
n order for a hurricane to form, two things must be present: a weather disturbance, such as a thunderstorm, that pulls in warm surface air from all directions and water at the ocean's surface that is at least 80° Fahrenheit (27° Celsius).
Astronomers use special equipment to study the electromagnetic spectrum. What is the electromagnetic spectrum?
Answer:Astronomers use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space. Even though all light is fundamentally the same thing, the way that astronomers observe light depends on the portion of the spectrum they wish to study.
Explanation:For example, different detectors are sensitive to different wavelengths of light. In addition, not all light can get through the Earth's atmosphere, so for some wavelengths we have to use telescopes aboard satellites. Even the way we collect the light can change depending on the wavelength. Here we briefly introduce observatories used for each band of the EM spectrum.
give two examples that demonstrates the law of reflection
You can see yourself in the mirror through the reflection of light and the waves of the ocean/water
Did you notice that the plant is hovering above the table in the photo? Try your own hand at getting a paper clip to hover. Attach one end of a string to a paper clip. Attach the other end of the string to the table. Move a magnet around the paper clip. Record your observations in the space below.

Which of the following is NOT laboratory evidence of a chemical reaction?
A. Large chunks of sodium chloride are placed in a mortar and pestle. The sodium chloride is broken into smaller pieces.
B. Hydrochloric acid is poured in a test tube containing a piece of magnesium. Bubbles of gas form.
C. A solution of silver nitrate is added to a solution of sodium chloride. A solid white substance forms.
D. A solution of sodium sulfide is added to hydroiodic acid. A rotten smell is given off.
Answer:
A. Large chunks of sodium chloride are placed in a mortar and pestle. The sodium chloride is broken into smaller pieces.
Explanation:
This is an example of physical change where the physical properties of the substance are altered without any formation of a new substance. So, it is not an evidence of a chemical reaction.
Did you notice that you could use the magnet to get the paper clip to move without
touching it?How was this similar to the floating plant?A change in motion can only happen when a force is acting on an object.What force was acting on the paper clip?Using the paper clip and the magnet as an example, make a claim how magnets can make an object move without touching the object.
Yes, I noticed that a magnet could be used to move the paper clip without touching it.
It is similar to the floating plant because both processes involve a force acting on an object without having a direct physical contact.
The force acting on the paper clip is described as the magnetic force,
The claim can be made that magnets could move an object without physical contact by using the magnetic force to exert a force on the object.
What is magnetic force?A magnetic field is described as a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.
In this case , the magnetic force arose due to the interaction between the magnetic fields of the magnet and the paper clip.
The magnet has a magnetic field around it, which exerts a force on any nearby magnetic material, such as the paper clip.

Explanation:
Analyze the data you collected from the lab paper clip pick up develop two or more questions based on the data that you could investigate to find out more about magnetic forces in each question underline the cause and italicize the effect
