what is states of water?? please give me an example or two!!! best answer will get marked brainliest
Answer: Three states of water are liquid, solid, and gas.
Explanation:
When water is at room temperature it is a liquid, when it is at 32° F or below it is at freezing temperature and will turn to a solid known as ice, when water reaches above 212° F it will evaporate into a gas.

In 3-5 complete sentences, compare the three ways that waves change direction.
Answer:
There are many ways to compare waves and how they change direction. The most common way is through the wind. This is different from human force because of direct contact in the wind and human force. However they both intact something physically moving the ocean. This compares how different waves move.
Explanation:
i tried my best to help!
Answer:
Reflection is the change in direction of a wave between two different objects such that the wave returns to the medium from which it began. In other words, the waves are sent back towards the source. Sound waves, light waves, and water waves can all be reflected.
Explanation:
Incident Ray – the wave/ray traveling towards a surface
Angle of Incidence – the angle at which the traveling wave/ra
y hits a surface
Equal (or Normal) – divides the two rays (incident / reflected) into two equal angles
Angle of Reflection – the angle at which the reflected wave returns towards the original medium
Reflected Ray – the wave/traveling away from the “hit” surface, and now traveling towards the original medium

When sound waves cause the eardrum to vibrate, these vibrations are immediately passed on to the _______________.
outer ear and ear canal
tiny hairs
three small bones in the middle ear
inner ear
Answer: three small bones in the middle ear
Explanation: Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.
When sound waves cause the eardrum to vibrate, these vibrations are immediately passed on to the three small bones in the middle ear. So, the correct option is C.
What are Sound waves?A sound wave is defined as a pattern of disturbance that is caused by the movement of energy that travels through a medium such as air, water or any other liquid or solid substance as it propagates away from the source of the sound which is the object made by vibration and pressure generate waves, for example, a ringing cellphone.
These waves enter the outer ear and pass through a narrow passage called the ear canal leading to the eardrum which vibrates with the incoming sound waves and sends these vibrations to three small bones in the middle ear where these bones are called malleus, incus. and steppes.
Thus, the correct option is C.

A hammer has an input distance of 9 cm and an output distance of 3 cm. What is its ideal
mechanical advantage?
Answer:
3cm should be the answer correct me if I'm wrong
Explanation:
Divide the input by the output
The ideal mechanical advantage of the hammer is the ratio of its input distance to the output distance . The ideal mechanical advantage of the hammer with input distance of 3 cm and output distance of 9 cm is 3 cm.
What is mechanical advantage?Mechanical advantage of an machine or an equipment is the measure that how much input force is changed to output. It is the ratio of output force to the input force. This ratio is the actual mechanical advantage of the machine.
The actual mechanical force also accounts for the frictional force also. The amount of input force needed to overcome the friction is considered here.
The ideal mechanical advantage the distance measurements are used since it is difficult to measure the input/output force.
given that, input distance = 9 cm
output distance = 3 cm.
ideal mechanical advantage = input distance/ output distance
= 9 /3 = 3 cm.
Therefore, the ideal mechanical advantage of the hammer is 3 cm.

How long will it take for an object to hit the ground when dropped from a height of 7m?
Answer:
Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.

I do not understand Net Force at all- I would really appreciate it! I'll also include a brainliest since it is quite a bit! Thank you!
Answer:
See below
Explanation:
Net Force is the force which is the sum of all the forces acting on object i.e. pushing of pulling.
Net Force:
1) 4N (net force is 4N to the left)
2) 2 - 7 = -5N (net force is 5N to the left)
3) 4 - 4 = 0 (net force Zero)
4) 6 + 3 = 9N (net force is 9N to the right)
5) 4 - 8 = -4N (net force is 4N to the left)
6) 4 - 5 = -1N (net force is 1N to the left)
7) -3 - 3 = -6N (net force is 6N to the left)
8) 2 + 4 - 5 = 1N (net force is 1N to the right)
9) 3 - 6 = -3N (net force is 3N to the left)
10. 4 + 4 - 7 - 1N (net force is 1N to the right)
