PLS HELP ASAP :(( You observe a car parked on the side of the road. If the car started to move, Which conclusion could you make?

The forces were balanced when the car was parked, but one or more forces changed. The total forces became unbalanced, causing it to move.
The forces were unbalanced when the car was parked. When the car moved, they became balanced.
The forces were balanced when the car was parked. The forces stayed balanced when it moved.
The forces were unbalanced when the car was parked, and two or more forces changed. The forces stayed unbalanced and caused the car to move.

Answer:

A (the first one)

Explanation:

An object is stationary when both forces acting on it are balanced. As soon as the car started moving, the driver had placed extra force on the accelerator and therfore the forces became unbalanced and the car moved

Using the Newton's law of motion to make conclusion about the scenario, the correct option would be ; The forces were balanced when the car was parked, but one or more forces changed. The total forces became unbalanced, causing it to move.

According to Newton's law, it states that a body will continue in a state of uniform motion or rest unless it is acted upon by a force to make it act otherwise "

Therefore, the forces were balanced when the car was parked, but one or more forces changed. The total forces became unbalanced, causing it to move.

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.

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.

How did Antonie van Leeuwenhoek become involved with the study of small particles?
A He studied ideas from the ancient Greeks
B He made lenses that magnified things
C He was a biologist who studied bacteria
D He experimented with atoms and electrons
What happened as a result of J.J. Thomson’s discovery of the electron?
A Scientists developed more powerful microscopes
B Scientists learned that the atoms were empty inside
C Scientists continued to discover smaller particles
D Scientists decided taking apart atoms was dangerous

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.
