They do the following experiment: (second image)
The students finish conducting their tests and conclude that using a taller ramp and a larger ball will make the ball roll further. Is their conclusion based on a reliable experiment?
A.Yes, because they used the same color balls.

suppose you are in a spacecraft traveling from earth to the moon. Will there be a point where the gravitational pull from earth and from the moon are equal? why?
Answers
Answer: There is no net force because the ship is beyond the influence of Earth and the Moon There is no net force because the forces erected by Earth and the Moon balance There is a net force because the force exerted by Earth is smaller than that exerted by the Moon.
Explanation:
Answer: there is a point in space between the earth and the moon where the force of gravity on an arbitrary object is equal in magnitude but opposite in direction and any object between the Earth and the Moon will be within the Sun's gravitational field. So there can be no point, where the gravitation field strength is zero

What would happen to the digestion process if enzymes were not present
Answers
Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.
Explanation:
I hope this helps
Without enzymes, the body would not be able to break down complex carbohydrates, proteins, and fats into their component molecules. This means that these nutrients would not be absorbed by the body and would be excreted as waste.
Additionally, the lack of enzymes would make it difficult for the body to digest and absorb vitamins and minerals. This could lead to malnutrition and other health problems over time.
Overall, the absence of enzymes from the digestive process would severely impair the body's ability to extract nutrients from food and could have negative consequences for overall health and well-being.
I don't understand how a shovel is a 3rd class lever.
isn't the load at the bottom? effort at the top? a fulcrum at the middle??? wouldn't that make it a first class lever? or am i just wrong?
Answers
Answer:
I think you are correct but you should still check gogle to be 100 percent sure
Explanation:
When you scoop up dirt with a shovel,
you put one hand on the top of the
shovel’s handle and the other on the middle of the shovel. The dirt, which is the load, sits on the shovel’s scoop.
The hand on the middle of the shovel is the one that does the work. This hand lifts the shovel and the load up from the ground.
The advantage of a third-class lever is that the load moves farther than the effort. You only need to lift the middle of the shovel a bit to raise the scoop with its load of dirt up quite a lot.

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J

List an example of matter in each of the three states.
Answers
The example of matter in the three states is brick in solid state, water in liquid state and oxygen gas in gaseous state.
1. Solid: A brick is a solid object that maintains a fixed shape and volume.
2. Liquid: A glass of water is a liquid that conforms to the shape of its container but maintains a definite volume.
3. Gas: Oxygen gas in the atmosphere is a gas that does not have a fixed shape or volume, filling the available space.
The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, such as an ice cube. Liquids have a definite volume but take the shape of their container, like water. Gases have neither a fixed shape nor volume and fill the entire space available to them, such as the air we breathe.
In summary, the states of matter describe the physical properties of substances based on the arrangement and movement of their particles, with solids having a fixed shape, liquids taking the shape of their container, and gases being free-flowing and filling all available space.

Solid: An object that keeps a constant shape and volume is a brick.
Thus, Liquid: A glass of water is a liquid that keeps a consistent volume while taking on the shape of its container. Gas: Oxygen gas fills the available space in the atmosphere and does not have a defined shape or volume.
Gas, liquid, and solid matter can exist in any combination. Solids, like an ice cube, have a set shape and volume.
Like water, liquids have a set capacity but adopt the shape of their container. Gases, like the air we breathe, have neither a set shape nor volume and fill all available space.
Thus, Solid: An object that keeps a constant shape and volume is a brick.

Answers
Answer:
Forty million years ago, the continent of India, which was being carried northward by the Indo-Australian plate, collided with Asia forming the Himalayan mountain range (fold mountains). Since the initial encounter, the subcontinent of India has moved 2,000 kilometers farther north at a rate of 5 centimeters a year, sliding beneath Asia as it moves. In 10 million years India will plow into Tibet a further 180km. This is about the width of Nepal.

hot dog until it reaches an internal temperature of 165°F, recording how long it took you to reach this
temperature. Based on your tests, you will make recommendations on how to improve the design of your
solar cooker, and then present your final design and the logic that supports it in a lab report. Your lab
report should include a title, a list of materials that you used to build your solar cooker, a drawing of your
initial design, observations from your experimental tests, recommendations for a final design based on
what you know about radiation, a drawing of your final design, and the results of the efficiency test. To

You and Tim, who is larger than you, are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon when it had the greatest acceleration during start-up? Why? Use Newton’s second law to explain.
Now Sara comes along, and she is the exact same size as you. However, she is even stronger than you! When she pulls you in the wagon, she pulls with a greater force than when you pull her. Now, who is in the wagon when it has the greatest acceleration? Explain, using Newton’s second law.
Answers
Answer:
I was riding in the wagon when it had the greatest acceleration during start up.
According to Newton's Second Law of Motion,
Force, F = [m = mass of the object, v = velocity of the object]
F = m + v
As the m is constant here, so the equation will be,
F = m
or, F = m×a , a is the acceleration
Between Tom and I,
Now, if the Force applied is same,
a ∝ 1/m
As Tom is bigger than me, so in the first case, I was riding in the wagon when it had the greatest acceleration during start up.
In the second case,
The force is not same.
Sara applies more force than both of us and she is the exact same size as me.
If m is same, then,
F ∝ a
So, in the second case, Sara is in the wagon when it has the greatest acceleration.
Explanation:
1. As both me and Tim have the same amount of force and are able to pull the same weight with the same effect. However, Tim’s weight is greater than mine, so when I pull him it’s harder at the start as he is bigger and heavier than me. If I was to be 35 kg and he was about ⅓ more my weight.
My power=Tims power
My weight<Tims weight This creates a gap
So in conclusion , Tims speed at the start would be greater than mine asI weight less than him.
2. My power<Sara’s power
My weight=Sara’s weight This creates a gap
This end up that Saras acceleration is greater than mine as she is even stronger than me.

Newton's second law is one of the most important in all of physics. For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and a (acceleration) are both vector quantities. If a body has a net force acting on it, it is accelerated in accordance with the equation.
