Answer:
A. acceleration
Explanation:
Acceleration is the increase of motion, it is the rate at which an object changes its velocity.
The rate at which an object's velocity changes is called its acceleration. The correct option is A.
The acceleration of an object is the rate at which its velocity is changing. The change in velocity per unit of time is measured by the vector quantity known as acceleration.
It explains how quickly an object's velocity is varying, taking into account both speed and direction variations. Depending on whether an item is speeding up, slowing down, or keeping a constant velocity, acceleration might be positive, negative, or zero.
Displacement is the change in an object's location, while scalar magnitude is the size or magnitude of a scalar quantity, which does not entail direction, and average velocity is the total displacement divided by the total duration.
Thus, the correct option is A.

Mahiya and Mrinmoy are in a relay around a square field with each side of length 60m. First, Mahiya runs at a speed of 6 ms−1 for 60m to pass a baton to Mrinmoy. Then Mrinmoy runs 120m at 4ms−1 while Mahiya runs through the field to reach the other corner. Then Mrinmoy passes the baton. But Mahiya is now tired since she has been constantly running. So, she only runs at 3ms−1 for the final 60m. What is the average speed of the baton in ms−1?
The average speed of the baton can be determined by dividing the total distance travelled by the total time taken for that travelling.
\(Average\ Time = \frac{Total\ Distance}{Total\ Time}\)
First, we will find the total distance, by adding the distances travelled by both Mahiya and Mrinmoy, while carrying the baton.
\(Total\ Distance = Distance\ Travelled\ by\ Mahiya\ to\ pass\ the\ baton\ to\ Mrinmoy\ +\ Distance\ Travelled\ by\ Mrinmoy\ to\ pass\ the\ baton\ to\ Mahiya\ +\ Final\ Distance\ Travelled\ by\\ Mahiya\)Total Distance = 60 m + 120 m + 60 m = 240 m
Now, we will find the total time taken for this travelling. To find out the total time we will divide each distance travelled by the speed of the traveller during that distance:
\(Total\ Time = \frac{60\ m}{6\ m/s}+\frac{120\ m}{4\ m/s}+\frac{60\ m}{3\ m/s}\\\\Total\ Time = 10\ s\ +\ 30\ s\ +\ 20\ s\)
Total Time = 60 s
Now, we finally find the average speed of the baton by using the formula:
\(Average\ Time = \frac{Total\ Distance}{Total\ Time}\\\\Average\ Time = \frac{240\ m}{60\ s}\)
Average Speed = 4 ms⁻¹

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

Answer:
(i did number 1) James Watt was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine. In 1762, he began studying steam engines. With his knowledge, in 1763, he repaired a "Newcomen" engine owned by the university. However, while repairing it, he was impressed by its waste of steam, and came upon a solution, the separate condenser. It was his first invention, and he created it in 1769. In 1765, he produced his first working model of the 'Watt' engine (with separate chambers for piston and steam). (i rly hope this helps no need to mark branliest if it doesnt)

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.
