Which statement accurately describes what happens when water turns to steam in terms of energy?
A.
The water absorbs energy which causes chemical bonds to break, changing water to steam.
B.The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from liquid to gas.
C.The water absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a liquid to a gas.
D.The water releases energy which causes chemical bonds to break, changing water to steam.
Answers
Final answer:
Water turns to steam by absorbing energy that increases the kinetic and potential energy of water molecules, allowing them to escape into the air as gas. So the correct option is C.
Explanation:
When water turns to steam, it absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a liquid to a gas. During the process of boiling, heat energy increases the water molecules' kinetic energy, leading to the breaking of hydrogen bonds that held water molecules close together. When these bonds break, water molecules can move freely and escape into the air as steam or water vapor. This endothermic transition requires a significant amount of energy due to water's high heat of vaporization.
The correct statement describing this change of state is thus:
C.The water absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a liquid to a gas.
Ashley made a paper boat and attached paperclips to the edges. In order to control her boat she used a horseshoe magnet. How is Ashley able to control her boat without touching it?
A) The boat is moving with currents in the water.
B) The boat is attracted to the magnet by the force of gravity.
C) The boat is attracted to the magnet by the force of magnetism.
D) Ashley would not be able to do this without touching the boat.
Answers
The true answer is C.
The boat is attracted to the magnet by the force of magnetism.
Let me explain. If Ashley made the paper boat and place it on the water, gravity will try to pull the boat down, however no magnets are used in this situation.
Now if magnets are used in this situation and the paper clip is attach to the boat, rather than gravity pulling it down, the magnet will be pulling paper clip, causing the boat to move, so instead of gravity, it's magnetism.

If the total number of earthquakes annually averages 14,500 approximately how many are magnitude 5 or higher? and show work.
Answers
Number x Percentage = Answer.
Therefore:
14,500x(90/100)=13,050
To find what percentage a figure represents of a total, do the following simple equation:
Figure/Total x100 = Percentage.
So for your Earthquakes, you have a total of:
Total = 90 + 20 + 5 + 1 = 116 Earthquakes.
4 to 5 -> 90/116 x100 = 78% to 2 sig. fig.
5 to 6 -> 20/116 x100 = 17%
6 to 7 -> 5/116 x100 = 4%
7+ -> 1/116 x100 = 1%
The same technique is used everywhere else, sample size divided by total multiplied by 100 gives percentage. Not multiplying by 100 gives you a ratio of 1 that it represents, 1 being 100% (a complete unit).
Therefore for part 1. of your question I would just do 14,500x0.9=13,050.
You'll probably see that 90/100 = 0.9 since 90% is identical to writing 90/100 or 0.9.

What class of solids is made up of regularly repeating subunits of tightly packed, orderly arrangements of atoms, ions, or molecules?
Answers
This means that if you take a look at the crystal under the microscope you would notice that there is a pattern that constantly repeats. This pattern is called a unit cell, and crystal is made up of stacked unit cells.
This means that if you're taking a glance at the crystal below the microscope you would notice that there's a pattern that perpetually repeats. This pattern is named a building block, and crystal is formed of stacked unit cells.
Explanation:
The constituents of a crystalline solid structure are organized spatially in a very regular and repetitive manner giving a very ordered structure. This extremely ordered arrangement is usually accompanied by a lowering of potential energy and hence energy in a type of heat is needed to convert it into liquid. This ordered arrangement commonly shows a smaller volume and lower squeezability issue than the liquids.
In crystalline solids the constituents could also be atoms ions or molecules, however, the order arrangement of those constituents that extends over an extended range in the crystal is best referred to as a long-range order.
Crystalline solids are thought-about as anisotropic because the magnitude of property depends upon the direction on that it's measured and crystal solids show precisely that unlike amorphous wherever the properties is freelance of direction.

Gamma radiation is produced during gamma decay.
When a nucleus undergoes alpha or beta decay it can be left excited.
An excited nucleus is unstable, it has an excess energy. A nucleus that is excited emits a photon to get rid of this excess energy and we call this process gamma decay. During a gamma decay, no particles are eject from the nucleus. Gamma rays are simply photons that have very high energies.

A soccer player practices kicking the ball into the goal from halfway down the soccer field. The time it takes for the ball to get to the goal from the time it is kicked averages about three seconds. The soccer field is 90 meters long. The player wants to know the average velocity of the ball. Is there enough information to calculate this?
A) No, only average speed can be calculated from the distance of 90 meters and the time of three seconds.
B) Yes, displacement is 45 meters, elapsed time is three seconds, and the direction is toward the goal.
C) No, only average speed can be calculated from the distance of 45 meters and the time of three seconds.
D) Yes, displacement is 90 meters, elapsed time is three seconds, and the direction is toward the goal.
Answers
The displacement of the ball is 45 meters elapsed time is 3 seconds, and the direction is toward the goal. Therefore, the average velocity is 15m/s. Therefore, option (B) is correct.
What is the velocity?The velocity of a moving object can be described as a vector measurement of the direction and the rate of motion of an object. The velocity can be defined as the change in the position of the object w.r.t. time.
Velocity can be described as a vector parameter as it exhibits both magnitude and direction. A mathematical expression to determine velocity is shown below:
v = d / t
where d is the distance moved by an object, and t is the time.
Given, the length of the soccer field = 90 meter
The distance traveled by the ball from halfway down the soccer field,
d = 90/2 = 45 m
The time taken by the ball, t = 3s
The average velocity of the ball, v = 45/3 = 15 m/s

The illustration shows a light ray striking an object.
In the illustration, the light ray striking the object is-
Question 15 options:
absorbed
stopped
refracted
reflected
Answers
In the illustration, the light ray is indeed reflected. Here's why:
Reflection is the phenomenon where light bounces off a surface and changes its direction. In the image, the light ray bends sharply back upon hitting the object, indicating this type of interaction.
Absorption occurs when light is captured by a material and converted into another form of energy, like heat. The illustration doesn't show any such energy dissipation.
Refraction refers to the bending of light as it passes from one medium to another, like air to water. The object appears solid with no clear interface for refraction to occur.
Stopped wouldn't be an accurate description as the light changes direction upon hitting the object. It continues propagating, just in a different path.
Therefore, reflected is the most fitting description for the behavior of the light ray in the illustration.
How much force is needed to stop an 80-kg football player if he decelerates at 5 m/s2? 5 N 16 N 20 N 400 N
Answers
Answer:
The force needed is 400 Newtons.
Explanation:
The force can be determined by means of Newton's law.
[tex]F = m \cdot a[/tex] (1)
Where F is the force needed to stop the football player, m is the mass of the football player and a is the acceleration.
[tex]F = (80 kg)\cdot (5m/s^{2})[/tex]
[tex]F = 400 kg.m/s^{2}[/tex]
However, 1N = 1 kg.m/s^{2}
[tex]F = 400 N[/tex]

What best describes the degree to which a material can transmit heat
- melting point
- boiling point
- thermal conductivity
- electrical conductivity
Answers
The correct answer is C. Thermal conductivity
Explanation:
Conduction occurs as heat, electricity, etc. are transmitted from one body to another. In the case of thermal conductivity, this refers to the property of one material or body to transmit or conduct heat. This property is measured in Watts (energy) per meter(distance)-Kelvin (temperature). For example, the thermal conductivity of copper is around 385 while the one of ice is 1.6, which indicates copper has a higher capability to conduct heat. Thus, the degree to which a material can transmit heat is thermal conductivity.
What is the mass of an object that weighs 55N on earth?
Answers
Force = Mass x Acc.
55N=mass x 9.8
so mass =55/9.8=5.61 aprox.
Now on the planet gravity mass is doubled
F =M x 2a
F =5.61x2x9.2
F=110N=110kg weight
With Earth's gravity being [tex]9.80 m/s^2[/tex] the mass is approximately 5.61 kg.
To calculate the mass of an object that weighs 55N on Earth, we need to use the formula for weight, which is w = mg, where w is weight, m is mass, and g is the acceleration due to gravity.
On Earth, g is typically [tex]9.80 m/s^2[/tex]
Therefore, we can find the mass of an object by dividing its weight by this acceleration due to gravity.
To calculate the mass (m) of an object that weighs 55N on Earth:
m = w / g
[tex]m = 55 N / 9.80 m/s^2[/tex]
This calculation results in a mass of approximately 5.61 kg.

A 1,600 kg car is traveling with a speed of 20 m/s. Find the net force that is required to bring the car to a halt in a distance of 50m. Use the formula: a= (vf2-vi2)/2d regarding the relation among acceleration a, final velocity vf, initial velocity vi, and the traveled distance of an object d.
Answers
Net force that is required to bring the car to a halt =6400 N
Explanation:
Using kinematic equation to calculate the acceleration a
Vf²= Vi²+ 2 a d
Vf= final velocity=0
Vi= initial velocity= 20 m/s
a= acceleration
d= distance=50 m
0²= (20)²+ 2 a (50)
a=-4 m/s²
Now force= F = ma
m= mass= 1600 kg
F= 1600 (-4)
F=-6400 N
negative sign indicates that the force is opposing the motion of the car.

Which of the following is true about diffraction?
a. Sounds with a larger wavelength bend around obstacles more easily.
b. Sounds with a smaller wavelength bend around obstacles more easily.
c. Sounds with higher energies bend around obstacles more easily.
Answers
Diffraction is sounds with a larger wavelength to bend around obstacles more easily. Therefore, option A is correct.
What is diffraction ?Diffraction is the interference or bending of waves via an aperture into the area that is geometrically in the shadow of the obstruction or aperture. Effectively, the wave's secondary source is the diffracting element or aperture.
The bending of waves with a larger wavelength around objects or through apertures with a shorter wavelength results in wave diffraction. If this condition is satisfied, diffraction can occur for both light and sound waves.
Wavelengths of visible light span from 380 to 700 nanometers. Light must pass through an opening that is smaller than 1,000 nanometers for diffraction to take place.
Thus, option A is correct.

Explanation:Diffraction refers to the bending of waves around obstacles or through small openings. In the case of sound waves, the correct answer is option a. Sounds with a larger wavelength bend around obstacles more easily. This is because sound waves have long wavelengths compared to the size of the obstacles. On the other hand, light waves have very short wavelengths and behave more like rays, so they do not diffract around large obstacles.
