The smallest particle in the universe?
A grain of salt is small, but you can always make it smaller. Imagine cutting that grain of salt into two pieces. Now cut it again and again. Soon, you can't see the smaller pieces with your eyes, but the salt is still there. You finally cut the salt down to the very tiniest piece of salt there is. But even that tiny piece contains smaller particles. Those tiny particles are atoms. Atoms make up everything in the visible universe from galaxies to even yourself. Atoms are so incredibly small that you could line up 50 million in a row and the line would only be about 1 centimeter (less than half an inch) long. Still, scientists have found things that are smaller than atoms. And they are looking for more. If they find the smallest things in the universe, they'll better understand how the universe actually works. But it took some time before people discovered the world of the truly small. The Universe Gets Smaller… Grains of sand or dust were once the smallest things actually seen on Earth. By the 1600s, several inventions opened up brand new worlds to curious minds. These included lenses that could make things look clearer and bigger. Another early invention was the microscope. Some people used the microscope to observe and write about the tiniest things they could see. In the 1670s, a Dutch lens maker named Antonie van Leeuwenhoek built himself a microscope. It magnified things more than 200 times. Van Leeuwenhoek discovered a world of tiny living things that he called tiny animals. Van Leeuwenhoek figured they were about 1/38th the size of a grain of sand. Today we know that what he saw were bacteria, the smallest living things on Earth. But atoms are much, much smaller. You can't see atoms with an ordinary microscope.
…And Smaller The idea that tiny, unbreakable particles make up everything that exists is more than 2000 years old. The Greek thinker Democritus called these particles "atomos." This is the Greek word for "uncuttable." Scientists didn't return to the idea of atoms until the 1800s. At first, scientists thought atoms were tiny balls with some electrical charges inside. They also thought atoms were the smallest particles that existed. But scientists soon began to wonder if atoms might be made of smaller things. In 1897, British scientist J. J. Thomson proved that they were. He ran experiments and discovered the electron. This tiny particle has a negative electrical charge and whizzes around inside the atom.

Protons, neutrons and electrons are shown.Zoom-in Different elements have different numbers of protons, neutrons, and electrons. The Smallest Things—So Far Scientists were soon discovering more inside the atom. Hiding in the atom's center is the tiny nucleus. (If an atom were the size of a racetrack, the nucleus would be about the size of a pea in the middle.) The nucleus contains two types of particles: protons and neutrons. Protons have a positive electrical charge while neutrons have no charge. They contain even tinier particles called quarks that are so unimaginably small that they have no internal structure. Quarks and electrons are the smallest particles found so far. Scientists call the smallest things they've found fundamental particles. Fundamental particles do not contain any smaller particles. Scientists use huge machines called particle accelerators to learn more about particles. These machines speed up particles so they can smash into each other. Then the scientists track the paths the particles leave when they hit. Scientists use accelerators to discover new particles. Many scientists wonder why there are so many particles at all. Shouldn't there be just one "smallest thing" instead of many? The search goes on for the particle that is the one true building block of everything in the universe

REALLY NEED HELP, 3 QUESTIONS 20 POINTS. ONLY ANSWER IF YOU KNOW THE CORRECT ANSWER. DO NOT ANSWER WITH "I DON'T KNOW, SORRY" JUST FOR THE BRAINLY POINTS. Thanks very much, have a great day. ( I Will report you if you answer with "I don't know, sorry"
1) A spring with a natural height of 60 mm is compressed by a 300 g mass to a new height of 54 mm.
 Find the spring constant in SI units.
 Find the height of the spring if the 300 g mass were replaced by a 400 g mass

2) A spring is stretched by 2m with a force of 100 N. Calculate its spring constant.

3) You have just bought an innerspring mattress that contains coil springs in a rectangular array 20 coils wide and 40 coils long. You estimate that when you lie on the mattress, your weight is supported by about 200 springs (about one-fourth of the total number of springs in the mattress). You observe that the springs compress
about 2.0 cm when you lie on the mattress. Assuming that your weight of 600 N is supported equally by 200 springs, find the force constant of each spring.

Use your answers from questions 1–3 as the basis for the first section of your lab report. This section provides your reader with background information about why you conducted this experiment and how it was completed. Outline the steps of the procedure in full sentences. It also provides potential answers (your hypothesis/es) relative to what you expected the experiment to demonstrate. This section should be 1–3 paragraphs in length.
