What are the formulas for Newton's 1,2,3 laws of motion?
How did he come up with the idea of his book?
Newton's three laws of motion can be summarized by the following formulas:
Law of Inertia, Newton's 1st Law of motion:
F = 0, or F = ma if there is an acceleration.
This means that if an object is at rest, it will remain at rest unless acted upon by an external force. Similarly, if an object is in motion, it will continue to move in a straight line at a constant speed unless acted upon by an external force.
Newton's second law of motion:
F = ma
This formula states that the acceleration of an object is directly proportional to the net force applied to the object and inversely proportional to its mass. In other words, the greater the force applied to an object, the greater its acceleration will be. Similarly, the greater the mass of an object, the smaller its acceleration will be for a given force.
Newton's third law of motion:
FAB = -FBA
This formula states that for every action, there is an equal and opposite reaction. In other words, when one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.
Isaac Newton's most famous book, "Philosophiæ Naturalis Principia Mathematica" (often called "the Principia"), was based on his own research and discoveries in mathematics and physics. The idea for the book came from his desire to develop a comprehensive system for explaining the workings of the natural world based on mathematical principles. He began working on the book in the 1660s, and it was first published in 1687.

Which of the following forces has not changed Earth's surface?
folding
erosion
weathering
gravity
Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

Refraction, or bending, of light rays as they move from one material to another occurs because light waves -
A: travel the same speed through all types of materials
B: travel at different speeds through different materials
C: are interrupted by sound waves as they travel
D: are compressed as they speed up
Answer:
A: travel the same speed through all types of materials
Explanation:
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. ... When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line.
Light travels the same speed.

Why is Christchurch, New Zealand’s air temperature cooler than usual during El Nino years?
Answer:
During normal years energy transfers from the ocean to the air. However, during El Nino years, the current is not as warm, so less energy will transfer from the current to the air, making Christchurch cooler than usual. During El Niño years, the normal prevailing winds are disrupted.

What fraction of the Moon model was always lit up by the light in your model?
Answer:10
Explanation:
In the context of the Moon model, the fraction of the Moon that was always lit up by the light is half, or 1/2.
The explanation for this is that the Moon model discussed previously most likely depicts the Moon's phases as seen from Earth. The phases of the moon are caused by distinct areas of the lit side of the moon that are visible from Earth at various times during its orbit.
The Sun always illuminates half of the Moon's surface, leaving the other side in darkness. From Earth, we can only see the bright portion; the unlit portion is invisible. Different phases result from variations in the visible fraction of the lighted half of the Moon as it revolves around the Earth.
Therefore, the fraction of the Moon that was always lit up by the light is half, or 1/2.

I know how the voltage increasing/not enough/stays the same and how long the battery lasts with series and parallel connections. But can someone explain the path electrons goes when you serie/parallel connect the batteries. I understand it with lamps but not batteries. Try to explain it as simple as possible because I'm a bit too young for this but I'm curious
Answer:
It comes out the positive side of the battery and goes in to the negative side of the battery
Explanation:
There are already electrons in wires in a circuit before you add the battery. By adding the battery, you're giving the electrons the energy it needs to move along the circuit.
In a series circuit, the circuit is one continuous loop so there is only one path for the electrons to go - out of the positive side of the battery and around the circuit then goes back into the negative side of the battery.
However, with a parallel circuit, there are two or more ways the electrons can go so they take the path of least resistance. The electrons still go out the positive side of a battery but along the circuit, the electrons will go through the path of least resistance ( I tend to think of it like a net with holes in it - the lower the resistance the bigger the holes for the electrons to go through so more can fit in a set amount of time ) but the electrons still go out of the positive side and in through the negative

The distance between the 2nd compression and the 3rd compression in a longitudinal wave is 200 cm. Find the wavelength of the wave.
I need the answer with working and formula..
Class - 8, Ch:13 - Sound, NCERT, CBSE
Explanation:
\(3 \times 200 \div 5\)
Answer:
The wavelength of the wave can be calculated using the equation λ = 2L/n, where L is the distance between two compressions and n is the number of compressions. In this case, the distance between compressions is 200 cm and the number of compressions is 3, so the wavelength is 133.3 cm.

According to the passage, carbon dioxide is the most abundant greenhouse gas on Earth. What is the leading cause of Carbon Dioxide rising in the last 100 years?
Answer the question using the CER strategy. Be sure to use evidence from source 1 and 2.
Answer:
Human activities, especially the burning of fossil fuels like coal, oil, and natural gas, are primarily to blame for the rise in carbon dioxide levels over the past 100 years. Carbon dioxide is produced as a byproduct of combustion when these fossil fuels are burned for transportation, industrial processes, energy production, and other uses. Together with other greenhouse gases, this human-caused release of carbon dioxide has significantly boosted atmospheric carbon dioxide concentrations, causing the greenhouse effect and amplification of global warming and climate change.
