A shift inward of the production possibilities curve signifies that _
A. The demand for the products has increased, so the supply will increase
B. The available resources have increased, so potential production levels will increase
C. The available production resources have decreased, so potential production levels will decrease
D. The demand for the products has decreased so, the supply will decrease
Answer:
c
Explanation:
A shift inward of the production possibilities curve signifies that: C. The available production resources have decreased, so potential production levels will decrease.
A production possibilities curve (PPC) is also referred to as production possibilities frontier (PPF) and it can be defined as a curve that illustrates the maximum (best) combinations of two (2) products which can be produce in an economy if they both depend on these two (2) main factors;
Fixed technology. Fixed resources.Basically, the production possibilities curve (PPC) illustrates the maximum combinations of goods that are available with fixed technology and resources.
Furthermore, an inward shift of the production possibilities curve (PPC) signifies that the available resources used for production have decreased, so potential production levels would also decrease.

Answer:
F = G M1 M2 / R^2
R^2 = G M1 M2 / F
R^2 = 6.67 E-11 * 6.78 E26 * 5.42 E20 / 8.6 E10
R^2 = 6.67 * 6.78 * 5.42 / 8.6 * E25

what's is meant by relative motion?
Relative motion means a motion relative to a reference point. We can also say, relative motion means motion referred or observed from a reference point.
For example, Alex is in a train and Ace is at the station, when the train starts moving, for Ace it is moving at a speed of 10 m/s, but for Alex it is moving at 0 m/s, or we can say that it is at rest for Alex, but in motion for Ace. This is relative motion.
Answer:
relative motion is the motion of an object compared to that of another object.for example two cars driving in the same highway in the same direction.

Adam is driving his truck at 18 m/s for a distance of 46 m, how much time was Adam driving?
Answer:
2.6 seconds
Explanation:
You have to divide the distance by the velocity to find the time:
46/18 = 2.55 ≈ 2.6 seconds
The answer you are looking for is approximately 2.6 seconds.
Solution/Explanation:
To get the correct answer, you must divide the distance and velocity.
This means that 46÷18=2.5556.
2.5556≈2.6.
So, therefore, the final answer is approximately 2.6 seconds.
I hope that this has helped you. Enjoy your day, and take care.

Which acid-base chemical reaction is irreversible?(1 point)
weak acid added to water
strong acid added to water
water on its own
weak base added to water
An irreversible reaction is a reaction that tends to completion. When a strong acid added to water, the reaction is irreversible.
In chemistry, a reaction may be reversible or irreversible. In a reversible reaction, the reaction could move forward or backwards. An irreversible reaction only tends towards completion. It doesn't goes in the reverse direction.
When a weak acid or base is added to water, the reaction is reversible because the substance does not ionize to a large extent in water and the equilibrium position may lie towards the far left. However, a strong acid or base achieves 100% ionization in water hence the reaction is irreversible.
Therefore, when a strong acid added to water, the reaction is irreversible.

1. strong acid added to water

A man jogs at a speed of 1.5 m/s. His dog
waits 2.5 s and then takes off running at a
speed of 2.6 m/s to catch the man.
How far will they have each traveled when
the dog catches up with the man?
Answer:
At t = 1.6 sec., the man has jogged 1.76m.
From that point on, the dog closes in on the man at the speed of 3.8 - 1.1 = 2.7m/s.
The time for the dog to catch the man is therefore t = 1.76/2.7 = .65s.
The man will have jogged .717m further for a total distance of 2.477m.
The dog will have traveled .65(3.8) = 2.477m.
Explanation:

If A man jogs at a speed of 1.5 m/s. His dog waits for 2.5 s and then takes off running at a speed of 2.6 m/s to catch the man, then they have to travel 8.85 meters each when the dog catches up with the man.
What is Velocity?The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
The unit of velocity is meter/second. It can also be represented by the infinitesimal rate of change of displacement with respect to time.
The generally considered unit for velocity is a meter per second.
As given in the problem If A man jogs at a speed of 1.5 m/s. His dog waits for 2.5 s and then takes off running at a speed of 2.6 m/s to catch the man,
When both the man and dog meet the distance covered by them would be equal.
Let us assume the time taken to catch up is t seconds when the dog takes off,
distance covered by man = distance traveled by the dog
1.5 ×t + 1.5×2.5 = 2.6 ×t
1.1t = 3.75
t = 3.75/1.1
= 3.40 seconds
Distance traveled during the catch-up = 3.40 ×2.6
Distance traveled during the catch-up = 8.85 meters
Thus, they have to travel 8.85 m each when the dog catches up with the man

how can I use theory and law in the same sentence in a scientific way and in every day use
Answer:
Explanation:
There are many laws in physics, that started out as theories and became scientific truths only after an experiment was performed that confirmed that the theory was true.
One of the most famous theories was the guess that the gravitational Force was a constant amount that depended on mass and distance. It was incredibly difficult to prove because the with large masses and small distances, the force is quite small.
Newton proposed the existence of the gravitational force in 1687 and Cavendish found its precise truth in 1798 -- 111 years after Newton said it was so.
Newton proposed a theory. Cavendish proved it to be a law later. Even then, Einstein proposed the modern law.

(A) the need to include both dependent and independent variables in every experiment (B) the need to write down procedures carefully so others can carry out the same experiment (C) the need to repeat an experiment many times to test results before drawing a conclusion (D) the need to evaluate the meaning of the experiment's results before drawing a conclusion
There are several models that outlines the scientific method, which is
based on formulating an hypothesis to answer observed phenomena, and
testing the hypothesis to see if it is correct

The four variables that must be controlled for the results of Maria and Elena to be valid are
TemperatureAmount of lightHumidity Time.Variables in an experiment are those values that can change.
When conducting an experiment, there are usually different types of variables that are used and one of such is the Controlled variables.
The Controlled variables are known as those extraneous variables that can affect the results ( dependent variables) of an experiment. Therefore they should be held constant in order to obtain a valid result.
Examples of such controlled variables are Temperature, Amount of light,
Humidity and Time.
Take for instance, If the experiment conducted by Maria and Elena has to do with the rate at which an enzyme acts on different substrates. The temperature of the experiment needs to be constantly maintained to achieve a valid result.
This is because an increased temperature leads to increased rate of reaction between the enzyme and the substrate.
Therefore the variables that must be controlled for Maria and Elena results to be valid are the controlled variables which includes Temperature, Amount of light, Humidity, Time.

The gravitational force F between two bodies of masses M and m, separated by a distance R, has a magnitude of
F = GMm/R ²
We're given that
F₁ = Gm₁m₂/r ²

Now,
F₂ = G (2m₁) (4m₂)/(2r )²
F₂ = 8/4 Gm₁m₂/r ²
F₂ = 2 Gm₁m₂/r ²
F₂ = 2 F₁
so n = 2.
