Answer:
Option C is correct
Explanation:
A supersaturated solution is one that has more solute dissolved than the solution should hold at that temperature.
Examples include carbonated water, sugar syrup, honey.
A solution of a chemical compound can be dissolved in heated water to prepare a supersaturated solution. A solution becomes supersaturated as its temperature is changed.

In three to five sentences, evaluate the scientific evidence that supports the big bang theory and the steady state theory.
The universe was created due to an explosion that occured in space and that the universe is expanding but still maintains an average density that's constant.
Briefing:The Big Bang Theory proposes that a space-based explosion led to the creation of the universe. The space expanded because of the extraordinarily high temperature and density. The elements were then created after the cosmos cooled.
According to the Big Bang Theory, the universe was created by a tremendous explosion that took place billions of years ago. The stars and galaxies that exist in our universe were formed when matter was drawn together by gravity.
The steady state theory is a description of the idea that although the cosmos is expanding, its average density remains constant.
The steady state theory claims that even though the cosmos is expanding, its appearance remains unchanged.
In conclusion, the steady state hypothesis and the big bang theory both describe how the universe came into being.

What are the theoretical properties of a gas at a temperature at 0 kelvin?
Answer:
The theoretical properties of a gas at a temperature of 0 Kelvin would be solid and hard. It will go from gas to liquid and finally to a solid state. All the particles will be mushed together. If a gas at zero degrees Celsius were cooled to -273 degrees Celsius, its volume would be reduced by 273/273 and become zero.

how much force is needed to accelerate 300 kg at a rate of 4 m/s/s
Answer:
1200
Explanation:
Force = Mass x Acceleration
Answer:
[tex]\boxed {\tt 1,200 \ Newtons }[/tex]
Explanation:
Force can be found by multiplying the mass by the acceleration.
[tex]F=m*a[/tex]
The mass is 300 kilograms.
The acceleration is 4 meters per second squared.
[tex]m= 300 \ kg\\a= 4 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]F= 300 \ kg * 4 \ m/s^2[/tex]
Multiply.
[tex]F= 1200 \ kg * m/s^2[/tex]
1 Newton is equal to 1 kilograms meters per second squared, so our current answer of 1200 kg m/s² is equal to 1200 Newtons.
[tex]F= 1200 \ N[/tex]
The force needed is 1,200 Newtons.

A thin film of oil with a thickness of 90 nm rests on top of a pool of water. When white light incident on the film is reflected, what color (wavelength of the first order) is seen? The refractive index of the oil is noil =1.45 and of water is nwater=1.33
Answer:
m=0, λ₀ = 522 10⁻⁹ m
Explanation:
In this case we can see that the first boy M The reflected light suffers an interference phenomenon, let's analyze what happens on each surface
* When light passes from a medium with a lower refractive index to a medium with a higher refractive index, it undergoes a phase change of pi rad (180º).
This occurs when passing from air to oil, but not at the oil-water interface.
* within the material the wavelength changes by the refractive index
λₙ = λ₀ / n
therefore introducing this into the constructive interference equation and assuming almost perpendicular incidence remains
2 t = (m + ½) λₙ
2t = (m + ½) λ₀ / n
λ₀ = 2t n / (m + ½)
light in the first order (m = 1)
λ₀ = 2 90 10⁻⁹ 1.45 / (1+ ½)
λ₀ = 174 10⁻⁹ m
the light for zero order (m = 0)
λ₀ = 2 90 10⁻⁹ 1.45 / (0+ ½)
λ₀ = 522 10⁻⁹ m

Given a helicopter flying up and sideways at a velocity of 95 m/s at an angle of 35º to the ground, find the horizontal component of the velocity.
Answer:
The horizontal component of the velocity of the helicopter is approximately 77.82 m/s
Explanation:
The given parameters are;
The speed of the helicopter, v = 95 m/s
The angle in which the helicopter is flying = 35° to the ground
The horizontal component of the velocity is given by the component of the magnitude, R, of the velocity of the helicopter in the x-direction as follows;
[tex]v = \sqrt{v_x^2 + v_y^2}[/tex]
Where;
vₓ = v × cos(θ) = The horizontal component
[tex]v_y = v \times sin(\theta)[/tex] = The vertical component
∴ The horizontal component of the velocity, vₓ, of the helicopter with 95 m/s velocity moving at an angle of 35° to the horizontal is given as follos
vₓ = 95 × cos(35°) ≈ 77.82 m/s
The horizontal component of the velocity of the helicopter ≈ 77.82 m/s.

Biomes on Earth have exhibited changes throughout history that have been caused by a variety of factors. Over the past 50 years, the amount of tropical rainforest acreage found throughout the world has decreased from 14.8 billion acres to 8.6 billion acres due to deforestation. What factor is likely most responsible for the changes observed in the world's rainforests? a. volcanic activity b. human activity c. temperature changes d. solar eclipses Please select the best answer from the choices provided A B C D
Answer:
b
Explanation:
The factor that is most likely to be responsible for the changes observed in the world's rainforest is human activities.
There has been a surge in the human population leading to an increased need for housing, foods, and other infrastructures. All these needs are directly or indirectly provided by the forest. Hence, the more the population of human expands, the more pressure that would be exerted on the rainforest and, indeed, other forests of the world.
The correct option is b.

pls help asap pls explain. Just before opening her parachute a skydiver having a mass of 50 kg reaches terminal velocity. Calculate the force of air resistance if the buoyant force is 20 N. Be careful! Use the skydiver’s mass to calculate his/her Fg (force of gravity).
Answer:
490N
Explanation:
Given that,
Mass of a skydiver, m = 50 kg
Buoyant force = 20 N
When the skydiver reaches the terminal velocity, net force on her is equal to 0. So, air drag is equal to the weight of the skydiver.
D = mg
Putting all the values,
D = 50 × 9.8
D = 490 N
So, the force of air resistance is 490 N.
A spray gun, used to apply paint, uses Bernoulli's principle to function. It contains two tubes inside of it: one tube comes up from the supply of paint and one supplies a flow of compressed air that blows across the top of the paint tube. This rush of air creates ____, which sucks the paint up the tube and into the stream of air.
Answer:
Low pressure
Explanation:
Take two nearby points at the junction of both the tube, let point 1 be in the air tube while point 2 be in the paint tube.
According to Bernoulli's principle, the air at point 1 is moving with some speed which causes the pressure drop inside tube 1, while at point 2 there is no velocity, so there is no pressure drop at that point. In fact, the pressure at point 2 approximately equals the atmospheric pressure.
As both the points are taken is nearby at the junction, to the pressure drop in the flow air pipe causes the suction of fluid from the relatively high-pressure tube (paint tube).
Hence, this rush of air creates low pressure, which sucks the paint up the tube and into the stream of air.

Janel did an experiment to see which spices can kill bacteria. She mixed a spice with bacteria food called agar. She poured the agar and spice mix into a petri dish(a plate used for growing bacteria) and added bacteria. She did the same for five different spices. This is an example of
Answer:
Antibacterial activity
Explanation:
The antibacterial property does not allow bacterias to live in an environment. Many spices have the ability to show antibacterial activity, few of these spices can be named as cinnamon, turmeric, or clove. Because they have antimicrobial or antibacterial characteristics that is why they are used for food preservation, disease prevention, and provide many health benefits. But, not every spice has antibacterial characteristics, that is why Janel experimented with five different spices to see which amongst them possess antibacterial characteristics.
Hence the correct answer is Antibacterial activity.
