Answer:

No

Explanation:

The reason why Barry's evidence isn't strong because "it's not enough to support his claim" that strong magnets repel and weak magnets attract. Barry needs to have at least three trials for each test to greater prove his claim. Doing so will show that the test isn't incorrect because he repeated the test multiple times and got the same results. If Barry does three trials for each test and record his results then he would have enough evidence to support his claim.

Hope this helps.

No, the evidence is not strong enough, as there is a lack of repetition and information on how the experiment was done.

The first thing that is missing is information on how the experiment was done, things like

Strong and weak magnets behave in the same way, opposite poles attract and equal poles are repelled, thus, there must be a problem with Barry's experiment.

Ignoring that, another problem is the lack of repetitions. An experiment must be done several times to see if the results are always the same, in the given evidence it was done only once for each, so we don't know if after another trial the outcomes will be the same.

Explanation:

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.

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

Answer:

simply because mass = velocity

Answer:

mass and speed

Explanation:

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 think a magnet can cause something to move if it has its own magnetical force or whatever you call it i forgot but you put the same pole to that sources pole. So move North pole to the other North Pole

Answer:The statement "The latent heat of vaporization of water is 226kj/kg." means the amount of heat energy needed to convert one kilogram of water from the liquid phase to vapor is 226kj/kg. Here, the term "latent" refers to a phase-changing process and the term "vaporization" refers to the phase change from liquid to gas

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.

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.

Answer:

The law of falling bodies is one of Galileo's key contributions to physics. It states that objects fall at the same speed regardless of weight or shape. Through his experiments, Galileo countered the pervasive Aristotelian view, which held that heavier objects fall faster than lighter objects.

Explanation:

Answer:

Galileo’s contribution to the study of motion is that he was the first to systematically study force and motion.

Explanation:

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)
