Describe what happens to the water molecules as heat energy is added and the water changes from solid to liquid to gas
Answer:
Explanation:
Adding heat can cause ice (a solid) to melt to form water (a liquid). Removing heat causes water (a liquid) to freeze to form ice (a solid). When water changes to a solid or a gas, we say it changes to a different state of matter. Even though the water's physical form changes, its molecules stay the same.
Which of the following did the doll experiment not suggest?
A. African Americans attributed more positive characteristics to the white dolls.
B. African Americans had feelings of inferiority because of school segregation.
C. African Americans preferred to play with the white dolls when given a choice.
D. African Americans felt more secure and positive because of school segregation.
Answer: I do believe the answer is D if not then sorry and let others know in the comment section
The doll experiment did not suggest the African Americans felt more secure and positive because of school segregation. The correct option is D.
What is school segregation?School segregation in the United States is the segregation of students based on their colors and caste. An institution can be predominantly owned by the black and only black students can study into it.
The Americans who are black belonged to the African continent. They felt more safety and secure by studying into this segregated school.
Thus, the correct option is D.

Mrs. Ernest wants to know how much light her daisies need. She places one pot of daisies under a sunlamp and another pot of daises on a windowsill. Each day she gives both plants the same amount of water. Which term BEST describes the amount of water given to the plants each day?
Answer:
Control Variable
Explanation:
A control variable is a variable that is held constant throughout the cause of an experiment, in order to test accurately the relationship between the dependent and the independent variables. The control variable, which is amount of water needed by the plants in this case, has the property of affecting the growth of the daisies, hence if it is not held constant, the result of the experiment might not be accurately attributed to the light source alone.
Therefore, to say with certainty that the difference seen in both categories of plants was from the difference in lighting alone, other variables (amount of water, type of soil, temperature etc.) has to be held constant

Which scientist's idea what "gases are formed from tiny particles so small you can't see them. The particles are spread out into a certain area and move when people walk through them."
Answer:
Bernoulli
Explanation:
Hello! I took the k12 science quiz! I hope you get an A!
Have a blessed day! :)
Bernoulli was the scientist who gave the idea that "gases are formed from tiny particles so small you can't see them. The particles are spread out into a certain area and move when people walk through them."
What is an ideal gas?It is an imaginary gas for which the volume occupies by it is negligible, this gas does not exist in a practical situation and the concept of an ideal gas is only the theoretical one,
Bernoulli was the scientist who gave the idea that "gases are formed from tiny particles so small you can't see them. The particles are spread out into a certain area and move when people walk through them."
The kinetic molecular theory of gases is stated via Bernoulli's principle. The hypothesis states that gas particles are tiny and separated from one another. But when things travel through them, they change from their position as a result of fluid dynamics.

a chemical reaction a temperature change may occur because of the breaking or formation of chemical bonds that release excess energy. Since there is a change in temperature why wouldn't this reaction be considered a physical change instead of a chemical change ?
Answer:
well, a chemical change will have to have something about its physically feature to be changed and it cannot be undone, say you burned wood, thats a chemical change as you cannot unburn it or remove the markings of the burn

A stunt man projects himself horizontal from a height of 60m. He lands 150m away from where he was launched. How fast was he launched?
A.) 54.87 m/s
B.) 43.98 m/s
C.) 47.46 m/s
D.) 42.87 m/s
Answer:
D) 42.87 m/s
Explanation:
First, find the time it takes him to land. Given in the y direction:
Δy = 60 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
60 m = (0 m/s) t + ½ (9.8 m/s²) t²
t = 3.5 s
Next, find the speed needed to travel the horizontal distance in that time. Given in the x direction:
Δx = 60 m
a = 0 m/s²
t = 3.5 s
Find: v₀
Δy = v₀ t + ½ at²
150 m = v₀ (3.5 s) + ½ (0 m/s²) (3.5 s)²
v₀ = 42.87 m/s

The graph above represents the motion of a car. Based on the graph, the car is most
likely-
A) driving up a steep hill
B) speeding up
C) driving at constant speed
D) decelerating
Answer:
Option (C)
Explanation:
From the graph attached,
Position of a car is changing with time.
Let the two points (1, 5) and (2, 10) define the positions of a car at the different moment of time.
Since, speed = [tex]\frac{\text{Distance traveled by the car}}{\text{Time taken}}[/tex]
= [tex]\frac{10-5}{2-1}[/tex]
= 5 meter per second
Speed of the car = slope of the line on the graph
Since slope of the line is constant, speed of the car will be constant.
Therefore, Option (C) will be the answer.

Why is the handle made of a different material than the rest of the pot?
Answer:
Hi there!
Your answer is:
The handle is made from a different material than the rest of the pot because you want to be able to safely move & touch the handle without getting burnt. The pot is made of conductors, like metal, to help it get hot quickly and cook evenly. You need to be able to touch the handle without being in danger, so the handle is made of an insulator, like wood, which doesn't get hot easily
I hope this helps!
Answer: the handle is made up of different material than the rest of the pot because the handle can conduct heat into your hand if its the same material.
A jogger runs at a constant rate of 10.0 m every 2.0 seconds. The jogger starts at the origin and runs in the positive direction for 3600.0 seconds. Hint: Draw a position- time graph.
a. Where is the runner at time t= 5.0 s?
b. Where is the runner at time t= 15.0 s?
Answer:
(a) 25 m
(b) 75 m
Explanation:
Given that the jogger runs at a constant rate of 10.0 m every 2.0 seconds.
So, the speed of the jogger,
[tex]v=\frac{10}{2}=5m/s\;\cdots(i)[/tex]
Let d be the distance covered by him in time, t s.
As distance=(speed) x (time)
So, [tex]d=vt[/tex]
From equation (i)
[tex]\Rightarrow d=5t\;\cdots(ii)[/tex]
As the jogger starts from origin, so, the distance, [tex]d[/tex], also represents the position of the jogger at the time [tex]t[/tex] s.
The position-time graph has been shown.
(a) From equation (ii), for t=5.0 s
[tex]d=5\times 5=25 m[/tex]
So, the jogger is at a distance of 25 m from the origin.
(b) Similarly, for t=15.0 s
[tex]d=5\times 15=75 m[/tex]
So, the jogger is at a distance of 75 m from the origin.

When is equilibrium reached? (5 points)
a
When supply is greater than demand
b
When demand equals supply
С
When supply is less than demand
d
When demand and supply both change
Answer:
Equilibrium is reached when demand equals supply.
Explanation:
Demand is the amount that consumers want and can buy of a certain product or service in a specific period of time and at a certain price. On the other hand, the supply is the amount that producers want and can sell of a certain product or service in a specific period of time and at a certain price.
In market equilibrium, the quantity demanded of the product or service equals the quantity supplied, so the price also equals. In other words, when market equilibrium is reached, demand and supply are the same, with their corresponding equilibrium price and quantity.
Two situations can occur:
When the quantity demanded is greater than the quantity supplied, the market is in a situation of excess demand. On the other hand, it may happen that the price at which the products are being offered is greater than the equilibrium price and the quantity supplied is greater than the quantity demanded. Then there is an excess supply.Equilibrium is reached when demand equals supply.
