I A. Certain mineral crystals have properties that help protect the

body from illness.

IB. A constellation's position in the night sky can be used to predict

events in a person's life.

I C. Medical data gathered over many years show that lack of

adequate sleep causes health problems.

D. Observations using microscopes reveal that all known organisms

are composed of tiny structures called cells.

I E. Data gathered during experiments show that there is an inverse

relationship between the force of gravity and distance.

Answers

Answer 1

Answer:

The correct options are A and B

Explanation:

Personal beliefs can be described as beliefs that have not been scientifically proven. These beliefs are generally as a result of religion, culture or tradition. Scientifically in theory, these beliefs lack clear path of possibility. For example, being in possession of certain mineral crystals in order to help protect the body against illness have a little possibility of being scientifically (in theory) explained. There is also no scientific evidence to support this claim.

There is also no scientific evidence to support the idea of the constellation's position to predict  events in a person's life. This also has little possibility of being theoretically explained in science.

It should however be noted that there are exceptions/coincidences that suggest these events happen as it has been listed in the two options.

energy of fossil fuels is also derieved from solar energy​

Answers

Answer:

Explanation:

All the energy in oil, gas, and coal originally came from the sun, captured through photosynthesis.for example when  we burn wood to release energy that trees capture from the sun, we burn fossil fuels to release the energy that ancient plants captured from the sun. We can think of this energy as having been deposited in a natural solar power bank over millions of years.

So, in one sense, gasoline-burning cars, coal-burning power plants, and homes heated by natural gas are all solar powered!

Which of the following periodic properties increases as you move from left to right across the periodic table?
A.
nuclear charge
B.
All of these answer choices are correct.
C.
electron affinity
D.
electronegativity

Answers

Answer:

the answer choice is B

Explanation:

as we move from left to right , the atomic size decreases due to higher number of protons in the nucleus, which are able to attract the electrons more strongly. and so the electronegativity and  electron affinity increases for the same reason. the nuclear charge increase due to more protons , and without an increase in inner electrons , there is less shielding effect. so effective nuclear charge increases.

Answer: B. electronegativity

Explanation: Electronegativity generally increases as you move of the periodic table and as you move to the right. All the other answers listed decrease as you move up a column of the periodic table.

present species live longer.

Answers

Answer:

today's species evolved from those of the past.

Explanation:

By comparing fossils of a specie from long ago to those of today, we can conclude that today's species evolved from those of the past.

Fossils are the preserved remains of ancient life forms found within sedimentary bed layers. These fossils helps scientists to understand ancient life forms. According to the discovery of Charles Darwin, organisms have evolved and are still evolving. Understanding past life forms gives a way to characterize present day species  better.

What is the mass of a car traveling at 5.6 m/s with a momentum of 3723 kg*m/s?

Answers

Answer:

m = 664.821 kg

General Formulas and Concepts:

Physics

p = mv

p = momentumm = mass (kg)v = velocity (m/s)

Explanation:

Step 1: Define variables

m = unknown

p = 3723 kg * m/s

v = 5.6 m/s

Step 2: Find mass

3723 kg * m/s = m(5.6 m/s)

m = 664.821 kg

When dividing, m/s and m/s cancel out to leave kg as our final answer

Two cars are on a track and accelerate to 60 mph. At a certain point, both cars slam on the brakes. The distance it takes for each car to stop is then measured.

3. Name the independent variable:
4. Name the dependent variable:

Answers

Answer:

'distance' is a 'dependent' variable, and 'stopping' distance is 'an independent' variable.

Explanation:

As we know the independent variable is basically the variable the independent variable is the variable the researcher or a lab person tends to change or control, and its tendency to have a direct effect on the dependent variable.

In this example, two cars are on a track and accelerate to 60 mph. At a certain point, both cars slam on the brakes. The distance it takes for each car to stop is then measured.

It means the 'covering' distance depends upon where the cars tend to stop. It can be a long-distance depending upon how fat the cars go before both cars slam on the brakes.

Therefore, 'distance' is a 'dependent' variable, and 'stopping' distance is 'an independent' variable.

Write some harms of friction.

Answers

Answer:

Friction produces unnecessary heat leading to the wastage of energy. The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects. Forest fires are caused due to the friction between tree branches. However, friction can also cause problems in a car. Friction between moving engine parts increases their temperature and causes the parts to wear down. Friction can be both harmful and helpful, so it may be necessary to decrease or increase friction.

Answer:

Friction had many disadvantages and these are the har,s of friction too.

Explanation:

Disadvantages of friction are mainly forest fires, decreasing life expectancy of vehicles, damages many machines, generates heat, wear and tear, wastage of force/energy, etc. When two things in a forest rub against each other through an amount of force, friction will be present and it will cause a spark. This spark will be continued into a fire because of other materials like wood in the forest causing a forest fire. Secondly, vehicles work through moving many internal machines in them; this again includes friction and friction can damage the machines so to prevent it ppl grease the machines. decreasing life of vehicles is just a larger view of damaging the machines as this disadvantage of friction can be used anywhere. Wastage of force/ energy because when we roll a ball on a surface we have to put force on the ball to make it move forward but because friction moves in the opposite direction energy/force will be wasted there. Generating heat and wear & tear are some factors of friction which is also a harm.
