Psycology is considered a social science while all the other choices are natural sciences.
Psychology is not considered a natural science. While it deals with the study of the human mind and behavior, psychology is generally classified as a social science rather than a natural science.
What are natural sciences?Natural science is a branch of science that deals with the study of the natural world, including the physical, chemical, and biological aspects of nature. It is a systematic and empirical approach to understanding the natural phenomena that occur in the universe. Natural sciences include subjects such as physics, chemistry, biology, geology, and astronomy, among others.
These sciences use the scientific method to investigate and explain the behavior of the natural world, relying on observation, experimentation, and analysis of data to formulate theories and laws that can explain natural phenomena. Natural science plays a critical role in our understanding of the universe and has contributed immensely to technological advancements in various fields. Therefore, option (B) is correct.

What does the term "heat capacity" refer to? Question 2 options: The amount of heat energy needed to raise the temperature of a unit mass of a material one degree A ratio of the amount of heat a material will absorb to the amount of heat it immediately releases The amount of heat that must be applied to a solid to convert it to a liquid The amount of heat that a liquid can absorb until the particles speed up enough to become a gas
Answer:
Heat capacity is the ratio of the amount of heat energy transferred to an object to the resulting increase in its temperature. Molar heat capacity is a measure of the amount of heat necessary to raise the temperature of one mole of a pure substance by one degree K.

A student walks to the right, 25-m along the C Hall in 15-s. They turn around and walk 15-m to the left in 8.0-s. What is the average speed and the average velocity? (V represents average speed and ΔV represents average velocity)
For the student that walks to the right 25 m in 15 s and then turns and walks to the left 15 m in 8.0 s, we have:
1. The average speed is 1.74 m.
2. The average velocity is 1.42 m.
1. The average speed is an scalar wich is given by:
[tex] V = \frac{d_{t}}{t_{t}} [/tex]
Where:
[tex]d_{t}[/tex]: is the total distance
[tex]t_{t}[/tex]: is the total time
The total distance and the total time can be calculated as follows:
[tex]d_{t} = d_{1} + d_{2} = 25 m + 15 m = 40 m [/tex]
[tex] t_{t} = t_{1} + t_{2} = 15 s + 8.0 s = 23 s [/tex]
Since V is a scalar, the direction of motion is not important to calculate the final value.
Then, the average speed is:
[tex] V = \frac{d_{t}}{t_{t}} =\frac{40 m}{23 s} = 1.74 m/s [/tex]
2. The average velocity is a vector, so the direction of motion is important here. This ΔV can be calculated with the following equation:
[tex] \Delta V = \frac{\Delta x}{\Delta t} = \frac{x_{f} - x_{i}}{t_{f} - t_{i}} [/tex]
Where:
x: is the displacement
f: is for final and i: is for initial
Hence, the average velocity is:
[tex] \Delta V = \frac{x_{f} - x_{i}}{t_{f} - t_{i}} = \frac{15 m - 25 m}{8.0 s - 15 s} = 1.42 m/s [/tex]

A bowling lane is 18 meters long. How long would it take a 1.5 m/s bowling ball to
roll down that lane?
16.5 seconds
16.5 meters
12 seconds
27 seconds
27 meters
12 meters
Divide distance by speed:
18 meters / 1.5 meters/ second = 12 seconds
Answer: 12 seconds
A bowling lane is 18 meters long. it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane, therefore the correct answer is the third option
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 mathematical expression for velocity is given by
velocity= total displacement/Total time
As given in the problem a bowling lane is 18 meters long and the ball is moving with a velocity of 1.5 m/s in the roll-down lane we have to find the time period for the bowling ball to roll down that lane
Total displacement = 18 meters
the velocity of the ball = 1.5 m/s
time =?
By substituting the values in the formula of the velocity
1.5 = 18/t
t= 12 seconds
Thus , it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane

In vector diagrams, what does the length of the arrow tell you?
Answer:
The length of the arrow tells you the size of the quantity in the vector diagram.
The direction of the arrow simply tells you the direction
Answer and Explanation:
A vector in this sense is a thing that has both magnitude (length) and direction.
Say you're walking at a speed of 5 miles per hour. If you keep walking in a straight line, then in two hours you will have walked 10 miles.
This doesn't give any information about where you started or any information about where you ended up after those 2 hours.
This is because "speed" is a scalar. It's a number with no associated geometry. It's just a magnitude. It's the magnitude of velocity.
Velocity is a vector.
Look on a map at where you are right now. Call that the center of the circle. Draw the circle with a 10 mile radius around where you are now.
The length of the arrow represents all of the possible places you could be after a two hour walk.
Which direction the arrow was pointing is what allows your friends to meet you there without checking along a ~63 mile path to find you or searching ~314 square miles to find you if you slowed down or stopped off along the way.

Answer:
The change in her position (from beginning to end), along with the direction, is considered her displacement.
Explanation:
Answer:
The change in her position ( from beginning to end), along with the direction, is considered her displacement. This value is a measurement and a direction. The total distance along the path from her starting point to her endpoint is considered her distance. This value is a measurement only.
