can someone please expain newton's second law of motion in a paragraph please? i'll give brainliest

Answers

Answer 1

Answer:

Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Friction is similar to drag. Like drag it acts on an object in the opposite direction from the object’s motion.


How does the friction slow motion?

Answers

Answer:

•  Friction is a force that occurs when two surfaces slide past

one another.

• The force of friction opposes the motion of an object,

causing moving objects to lose energy and slow down.

• When objects move through a fluid, such as air or water, the

fluid exerts a frictional force on the moving object. The

frictional force from a fluid is called a drag force.

• Friction examples: tires skidding to a stop on a road,

sandpaper rubbing against wood, air pushing against the

nose of an airplane

• Friction drag force causes objects to slow down as they move through a

fluid, such as air or water.

• Drag force depends primarily on the following variables:

– Cross‐sectional area of an object moving through the fluid

– Speed of moving object

– Density of the fluid

– Drag coefficient (determined by experiments; related to the shape of

the object)

• Drag force is especially dependent on the speed of an object. As an

object’s speed increases, the drag force from the fluid increases

exponentially.

• For example, when you drive at high speeds, the frictional force of air on

the car increases and fuel economy decreases

1. Tom and Tina decided they wanted to start a family. Tom knew his grandfather had sickle-cell disease. Sickle-cell disease is a recessive disorder that causes blood cells to stiffen and take on a crescent shape. These blood cells have a difficult time moving through the blood vessels and can cause health problems. Tina didn’t know of any family members that had it. Still, before they got pregnant they both went to the doctor for genetic tests. The doctor found that even though Tom and Tina were healthy, they both carried the gene for sickle-cell disease. Make a Punnett Square to determine the probability of Tom and Tina’s child having sickle-cell disease.

What is the function of peristalsis?

Multiple choice question.

A)
to move food through the digestive system


B)
to remove excess liquid from the body


C)
to chemically digest food to release nutrients


D)
to absorb nutrients into the blood

Answers

Answer:  A

Explanation

The digestive tract carries out the function of peristalsis by moving food through the system.  Peristalsis also removes excess liquid from the body.  Chemical digestion breaks down food into small nutrients, but this process does not involve peristalsis.  Finally, absorption of nutrients into the blood does not fall under the purview of peristalsis.

A
It is the wave like contractions and relaxation of the gullet to pull down food into the stomach

OK, you can say:

Waxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures. They include higher alkanes and lipids, typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids. Waxes are insoluble in water but soluble in organic, nonpolar solvents. Natural waxes of different types are produced by plants and animals and occur in petroleum.

i dont think that’s how it works

scientist created diagram X to represent the molecules of a kind of gas in a closed container. Diagram Y represents the molecules in the container after the size of the container was reduced. The temperature in the container was not changed. What most likely happened to the system when the scientist changed the size of the container? A. Matter was added. B. Matter was removed. C. The pressure increased. D. The pressure decreased.

Answers

Why is your account my name and yours

The most likely outcome when the scientist changed the size of the container is that the pressure increased.

Option (C) is correct.

When the size of the container is reduced while keeping the temperature constant, the gas molecules experience a decrease in volume. According to Boyle's law (P₁V₁ = P₂V₂), if the volume decreases, the pressure of the gas will increase.

Diagram X represents the initial state with larger volume, and diagram Y shows the final state with reduced volume. Since the temperature remains constant, the pressure must change to counterbalance the change in volume.

As the volume decreases, the gas molecules have less space to move around, and they collide more frequently with the container walls. This increased collision rate results in a higher pressure exerted by the gas on the container walls.

Hence, the most likely outcome when the scientist changed the size of the container is that the pressure increased, which corresponds to option C.

How would you classify this atom of oxygen?

Answers

Answer:

Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus. Oxygen is a gas at room temperature and has no colour, smell or taste. Oxygen is found naturally as a molecule.

Ion Anion an ion is a negatively or positively charged atom or radical
It’s atomic number is 8 which means it’s electronic configuration is 2,6 but it has 8 electrons in the l shell which means it is a negatively charged ion since the number of electrons is more than the number of protons. Anion is a negatively charged ion,cation is a positively charged ion

The statement which is true for a radioactive isotope is " they break down quicker than stable isotopes because they are unstable and undergo decay.

What is radioactive isotope?

A radioactive isotope is an isotope of an element which is under exposure to a radiation undergoes decay and breaks into lighter isotopes.

Radioactive isotopes are generally heavier and are unstable with short life time. They undergo radioactive decay by alpha/beta or gamma radiation to form stable lighter or smaller isotopes.

Therefore, option C that is, they  break down quicker than stable isotopes is correct.
