Myopia
Explanation:
myopia is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry. It occurs when the shape of your eye causes light rays to refract incorrectly, focusing images in front of your retina instead of on your retina. It can be corrected corrected with eyeglasses, contact lenses or refractive surgery.

A moving car of mass 500 kg collides with a stationary truck of mass 1500 kg, and the two vehicles lock together on impact. The combined velocity of the car and truck after the collision is 20 m/s. The velocity of the car before the collision is _______ m/s.
What is the velocity of the car before the collision?
Answer:
The car was approximately moving at 80m/s
A tennis ball forgotten on the court after match is:
A. Potential energy
B. Kinetic energy
C. Forgotten energy
Answer:
A. or C. but I think A.
Explanation on:
It's potential because it's not in motion so it can't be kinetic but somebody can pick it up any moment.
The theory of plate tectonics describes how the Earth’s lithosphere is broken into plates and these plates move over the molten magma below. Why is this considered a theory and not a law?
A. a theory is can not be proven and is based on opinion, a law is based on facts
B.A theory is developed by a single person or small group a law is developed by a large group of scientists
C. A theory can be modified as new evidence is uncovered, a law describes a relationship under certain conditions
D. A theory is developed by observing something under certain conditions and a law can be modified as new evidence is uncovered
Answer:
C
Explanation:
A theory can be changed when new evidence is found. A law doesn't change because it is universally a fact. It doesn't need new evidence to support it.
A theory can be modified as new evidence is uncovered, a law describes a relationship under certain conditions. Therefore, option (C) is correct.
What is the difference between theory and the law?
Theories and laws explain science, but they are different. Law describes what happens under certain conditions while theory explains why. This distinguishes theory from law.
Explanations of a phenomenon are referred to as theories. The workings of nature can be explained by theory. The law not only explains what happens in nature when certain conditions are met, but it can also predict what will happen in the future if those conditions are met. A theory is typically more descriptive and complicated than a law, with detailed explanations or multiple supported hypotheses.
Therefore, the theory of plate tectonics is considered a theory.

pls be creative this is due tomorrow and creativity is counted
Answer:
1st Law: A book lying on the table remains at rest as long as no net force acts on it.
A rolling ball on rough surface or ground stops earlier than on the smooth surface because rough surfaces offer more friction than a smooth surface.
A stone in the ground is in a state of rest.
The marathoner continues to run several meters beyond the finish line due to the law of inertia of his career.
2nd Law: Pushing a broken down car among more people will make the car move faster.
A lady teaches two children to ride a bicycle: one 4-year-old and the other 10-year-old, so that they arrive at the same place, they will have to exert more force when pushing the 10-year-old boy because his weight is greater.
A car needs a certain amount of horsepower to be able to drive on the road.
Imagine two people, one with more force than the other, pushing a table, in different directions. The person with greater strength is pushing towards the east, and the person with less force towards the north.
3rd Law: If one billiard ball hits another, the second will move with the same force as the first.
A man deflates a balloon; the force with which the air comes out causes the balloon to move from one side to the other.
A child wants to jump to climb a tree (reaction), he must push the ground to propel himself (action).
Hammer pushes a nail.

whats an example of kinetic energy
Answer:
A semi-truck travelling down the road has more kinetic energy than a car travelling at the same speed because the truck's mass is much more than the car's. A river flowing at a certain speed comprises kinetic energy as water has certain velocity and mass.
