1. Select all that apply.
aalyn [17]

The answers are as follows:

1. A scientific theory: <em>i)  is supported by evidence  ii) can evolve over time  </em>

A scientific theory can be defined as a set of interconnected statements or information about a particular topic, that has consistently been found by various scientists during repeated experimental investigations over time. For a scientific theory to be accepted as a theory, it must be backed up by empirical and scientifically derived data and statistics. Additionally, scientific theories are not absolute and can evolve and expand over time, if new valid and reliable data about the same topic is found.

2.  A chemist is likely to: <em>i) analyze the ingredients in ice cream ii) determine how to separate gasoline from other substances in petroleum </em>

A chemist is a scientist who specializes in topics related to Chemistry. A chemist investigates topics such as: elements, compounds, chemical reactions, chemical properties etc. Thus, a chemist is likely to analyze the ingredients in ice cream, in order to determine its chemical composition. Additionally, a chemist would investigate how to separate gasoline from other substances in petroleum, since this procedure would involve some form of chemical reactions.  

3. Science can be applied to:<em> i) government regulation ii) healthcare iii) telemarketing iv) environmental engineering v) banking </em>

Science can be defined as a broad and widely encompassing discipline that systematically and empirically investigates living organisms, their behavior, the physical world they live in, etc., through experimentation and observation. Science applies to government regulations since it can help shape the policies that the government enforces- such as policies that enhance the health and well-being of citizens. Healthcare and environmental engineering are sciences, and therefore, obviously contain scientific elements. Banking also involves science, since research, planning, policies, etc., require research.  

4. The fields of science and mathematics are so interdependent because:<em> i) Scientists need to be able to take careful measurements. ii) Scientists need to be able to make precise measurements. </em>

In simple terms, mathematics and science are interdependent, because both involve calculations in order to reach a solution or a conclusion. This is especially apparent in Physics (a science), which uses several calculations to prove laws and theories. Similarly, sciences, including: psychology, biology and chemistry, also involve mathematics and calculations in order to analyse data and reach conclusions. Both Mathematics and Science require careful and precise measurements in order to obtain accurate results.

5. The following questions can use science as a method of inquiry: <em> i) How can we protect crops from drought? ii) Did dinosaurs exist? </em>

Out of all the options listed in the question, only the aforementioned questions can use science as a method of inquiry. This is because, questions such as “Is cloning appropriate?” and “Why is jazz a great type of music?”, are qualitative and subjective in nature, and cannot be answered using scientific investigation- which involve measurements and statistical analyses. On the other hand, investigating how to protect crops from drought and the existence of dinosaurs can use science as a method of inquiry, because these investigations would involve measurement and analyses in order to obtain results and a valid conclusion.

When you jump, you push down on the earth and it pushes back up against you. The earth pushing up against you is what causes you
MissTica

That's a great question !

The answer is:<em> It does !</em>

A push on an object causes the object to <u><em>accelerate</em></u> in the direction of the force.  

The <em>less</em> mass the object has, the <em>more</em> the force accelerates it.

Now, when you jump, the forces on you and on the Earth are equal forces.

The up force on you causes you to accelerate up by some amount.

The down force on the Earth causes the Earth to accelerate down by some amount.

The Earth's mass is something like 5,972,000,000,000,000,000,000,000 kg, while your mass is something like 50 kg.

The Earth has something like 119,400,000,000,000,000,000,000 <em>times</em> as much mass as you have.

So your acceleration is something like 119,400,000,000,000,000,000,000 <em>times as great as the Earth's acceleration.</em>

==> The Earth's downward acceleration, caused by your jump, is there.  It's just too small to notice.

<em>BUT . . .</em> That's the reason why seismometers (instruments to detect and measure the vibrations from distant earthquakes) have to be located as far as possible from cities and busy roads.

In places that are too close to cities and roads, the Earth's surface is always vibrating, wiggling, jiggling, heaving and weaving, in reaction to the forces of people walking around, cars and trucks driving around, even rain falling down.  And kids jumping up and down !  

In such places, these people-motions are louder and stronger than the vibrations coming from distant earthquakes.  Seismometers wouldn't work there.

A bicyclist travels at the speed of 25 kilometers per hour for 5 hours. How far does the bicyclist go?
mixas84 [53]

Answer:

125 kilometers

Explanation:

Speed= 25km/h

Time = 5 h

Distance= Speed x Time

= 25 x 5

= 125 km

By how much does the pressure of a gas in a rigid vessel decrease when the temperature drops from 0 ∘C to –1∘C?
Ugo [173]
When a problem says a rigid vessel, it means that volume is constant. At constant V, pressure and temperature are indirectly proportional. We calculate as follows:

P1/T1 = P2/T2
P1/P2 = T1/T2
P1/P2 = 273.15 / 272.15
P1/P2 = 1.00

Hope this helps. Have a nice day.

Two light waves, initially emitted in phase, will interfere constructively with maximum amplitude if the path-length difference
777dan777 [17]

Two light waves will interfere constructively if the path-length difference between them is a whole number.

<h3>SUPERPOSITION</h3>

The principle of superposition state that, when two or more waves meet at a point, the resultant displacement at that point is equal to the sum of the displacements of the individual waves at that point.

Interference of waves can either be constructive, or destructive.

The two light waves, initially emitted in phase, will interfere constructively with maximum amplitude if the path-length difference between them is a whole number of wavelenght 1λ, 2λ, 3λ, 4λ etc

The equivalent phase differences between the waves will be 2\pi or 360 degrees, 4\pi or 720 degrees, 6\pi 1080 degrees etc

Therefore, the two light waves, initially emitted in phase, will interfere constructively with maximum amplitude if the path-length difference between them is a whole number.
