Answer: liquids take the shape of the container they are in, but have definite volume. like liquids the shape of a gas changes with the container. unlike liquids the volume of a gas changes depending on the container it is in
Explanation:
Answer:
liquids flow freely, they take the shape of the container they are in, but have a definite volume. Like liquids, the shape of a gas changes with the container. This is because the atoms in a gas move rapidly and freely to fill any available space. Unlike liquids, the volume of a gas changes depending on the container it

The x axis shows Surface Temperature in Kelvin, decreasing from left to right. Supergiants are yellow white, luminosity between 10 superscript 4 solar units and 10 superscript 5 solar units. Main is blue white, luminosity 10 superscript 4. Sequence is blue white, luminosity 10 superscript 3. Giants are red and orange, luminosity between 10 superscript 2 and 10 superscript 3. Sun is yellow, luminosity between 1 and 10. AB Doradus C is red, luminosity 10 superscript negative 3.

Which characteristic describes the stars indicated by the arrow in the image?
cool
hot
large
small
Answer:
The answer is cool.
Explanation:
If you look at the diagram then you can see that the star being pointed to is orange-ish. Red and orange stars are the more cooler ones.
Cool is the characteristic that describes the stars indicated by the arrow in the image. Therefore, the correct option is option A.
What is star?A star is an extremely bright ball of primarily hydrogen and helium-based gas that is kept together through its own gravity. The star is supported against gravity by nuclear fusion events at its core, which also yield photons, heat, and trace quantities of heavier elements.
The star is created when hydrogen nuclei start to fuse into helium nuclei at a temperature of roughly 10 million K (18 million °F) in the gas. The expanding star's core emits energy through nuclear fusion, which eventually slows the gas cloud's collapse. Cool is the characteristic that describes the stars indicated by the arrow in the image.
Therefore, the correct option is option A.

Does the mass of an object dictate the acceleration of
a falling object
Answer:
No.
Explanation:
Because the acceleration of falling objects is constant and is not affected by mass
Answer: no
The acceleration of an object is equivalent to the gravitational acceleration. The size, shape, and weight of an item are not a cause in the motion of the object. So all objects, regardless of its mass, size, or shape fall freely with the same acceleration.
What is TRUE about a capitalist society?
The idea behind capitalism is that the free market of products and ideas is owned and driven by private citizens. A capitalist society is a social order in which private property rights and the free market serve as the basis of trade, distribution of goods, and development.
Answer:
In ideal terms: In a capitalist economic system, the owner of production is the individual, and the benefactors of production are first the individual and second the society. In a socialist or communist economic system, the owner of production is the state or the society, and the benefactor is the society.
A 25 N force is applied to a 1.4 kg mass on level ground. If a 5 N frictional force is present between the surface and the object, what is the magnitude of the acceleration of this object?
Given parameters:
Force applied to the mass = 25N
Mass of the body = 1.4kg
Frictional force = 5N
Unknown:
Acceleration of the object = ?
Solution:
The net force on the object;
Fapplied - Frictional force = net force (m x a)
m is the mass of the body
a is the acceleration
Input the parameters and solve;
25 - 5 = 1.4 x a
1.4a = 20
a = [tex]\frac{20}{1.4}[/tex] = 14.3m/s²
The magnitude of the acceleration of the object is 14.3m/s²

Paco was driving his scooter west with an initial velocity of 4 m/s. He accelerates at 0.5 m/s for 30 seconds.
What is his final velocity?
O 2 m/s
O 8 m/s
O 19 m/s
O 60 m/s
Answer:
the answer is 19 ,30 (second) times 0.5= 15
15+4= 19
After Paco drives his scoter west with an initial velocity of 4 m/s and then accelerates at 0.5 m/s² for 30 s, his final velocity is 19 m/s, so the correct option is the fourth.
The final velocity of Paco can be calculated with the following equation:
[tex] v_{f} = v_{i} + at [/tex]
Where:
[tex] v_{f}[/tex]: is the final velocity =?
[tex]v_{i}[/tex]: is the initial velocity = 4 m/s
a: is the acceleration = 0.5 m/s²
t: is the time 30 s
Hence, the final velocity is:
[tex] v_{f} = 4 m/s + 0.5 m/s^{2}*30 s = 19 m/s [/tex]
Therefore, the correct option is 19 m/s.

What are three key aerodynamics principles?
A Drag, height, and acceleration
B Drag, downforce, and drafting
C Acceleration, downforce, and motion D Acceleration, height, and motion
Answer:
A
Explanation:
There are three basic forces in aerodynamics: acceleration, which moves an airplane forward; drag, which holds it back; and height, which keeps it airborne. Lift is generally explained by three theories: Bernoulli's principle, the Coanda effect, and Newton's third law of motion.
What is symbiosis
A an interaction between organisms
B a type of reproduction
C and organelle in the cell
D a process by which plants make their own food
Answer:
A an interaction between organisms
Explanation:
Symbiosis is an interaction between two or more organisms. It is a biological interaction which can be mutualism, commensalism or parasitic.
Mutualism is a form of interaction between two organisms where they both derive benefit from one another. Commensalism is an interaction in which one organism derives benefit and the other is neutral. Parasitic is an interaction where an organism derives benefit from the other in which the other is harmed.Symbiosis simply entails the interactions between organisms.

Which do you think is more likely: humans visiting an alien planet or aliens from another planet visiting us?
Plz someone help
Answer:
Explanation:
According to me, humans visiting an alien planet is more likely. This is because the allien planets may not have higher levels of technology.
Whereas in today's world, the technology have come to aqquire a very high position. So it likely that humans could visit the alien planets because of the technology evolved by them.

"A car is travelling at 70 m/s. The driver sees a cow in the road and slows down with a constant acceleration for 10 seconds before coming to a stop. What is the car’s displacement by the time is stops." what information do you know?
The question does not ask for anything in particular. I will calculate the acceleration and distance.
Answer:
The acceleration of the car is [tex]-7\ m/s^2[/tex]
The distance traveled before stopping is 350 m
Explanation:
Constant Acceleration Motion
It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:
[tex]v_f=v_o+at\qquad [1][/tex]
The distance traveled by the object is given by:
[tex]\displaystyle x=v_o.t+\frac{a.t^2}{2}\qquad [2][/tex]
The car has an initial speed of v0=70 m/s when the driver sees a cow in the road and steps on the brakes with an (assumed) constant acceleration during t=10 seconds before stopping (vf=0).
With the information provided, we can calculate the value of the acceleration and the distance traveled.
Using the equation [1] we can solve for a:
[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]
Substituting the numerical values:
[tex]\displaystyle a=\frac{0-70}{10}=-7\ m/s^2[/tex]
The acceleration of the car is [tex]-7\ m/s^2[/tex]
The distance is now calculated by using [2]
[tex]\displaystyle x=70\cdot 10+\frac{(-7)\cdot 10^2}{2}[/tex]
[tex]\displaystyle x=700-\frac{700}{2}=350\ m[/tex]
The distance traveled before stopping is 350 m
