materials generally become warmer when light is reflected by them. absorbed by them. transmitted by them. all of these none of these
Materials generally become warmer when they are "absorbed" by light, this statement is more detailed. So, the correct answer is "absorbed by them."
Explanation: When a material absorbs light, it receives energy from the light, which leads to an increase in temperature. When light is absorbed by a material, the energy of the light is transformed into internal energy in the material. The temperature of a material can increase as a result of this energy absorption.
This is due to the fact that the increased internal energy of the molecules in the material causes them to vibrate more quickly and hence results in a temperature rise.
The light reflects or transmits when it passes through the material. When light reflects off a surface, it bounces back in the opposite direction. Transmitted light travels through a material without being absorbed by it.

he pineal gland produces oxytocin and serotonin. true false
False. The pineal gland produces melatonin, not oxytocin and serotonin.
False. The pineal gland primarily produces melatonin, a hormone that regulates sleep-wake cycles. Oxytocin is produced by the hypothalamus and stored in the pituitary gland, while serotonin is primarily produced by specialized cells in the gastrointestinal tract and also in the brain.It is not entirely accurate to say that the pineal gland produces oxytocin and serotonin.The pineal gland is primarily responsible for producing and secreting the hormone melatonin, which helps regulate the body's sleep-wake cycle. While the pineal gland does contain some serotonin-producing cells, it is not a major source of serotonin in the body. Similarly, while oxytocin has been detected in the pineal gland, it is primarily produced by the hypothalamus and released from the posterior pituitary gland.Therefore, the statement that the pineal gland produces oxytocin and serotonin is false.

The beta decay of cesium-137 has a half-life of 30.0 years. How many years must pass to reduce a 25.0 mg sample of cesium-137 to 9.38 mg?
Answer:
t = 42.4 years
Explanation:
To find the amount of time needed for the sample to decay, you need to use the half-life equation:
\(N(t) = N_0(\frac{1}{2})^{t/h}\)
In this equation,
-----> N(t) = final mass (mg)
-----> N₀ = initial mass (mg)
-----> t = time passed (yrs)
-----> h = half-life (yrs)
You can find how much time passed by plugging the given variables into the equation and solving for "t". The final answer should have 3 sig figs like the given values.
N(t) = 9.38 mg t = ? yrs
N₀ = 25.0 mg h = 30.0 yrs
\(N(t) = N_0(\frac{1}{2})^{t/h}\) <----- Half-life equation
\(9.38mg = 25.0mg(\frac{1}{2})^{t/30.0yrs}\) <----- Insert variables
\(0.3752 = (\frac{1}{2})^{t/30.0yrs}\) <----- Divide both sides by 25.0 mg
\(ln(0.3752) = ln((\frac{1}{2})^{t/30.0yrs})\) <----- Take the natural log of both sides
\(ln(0.3752) = \frac{t}{30.0yrs} ln(\frac{1}{2})\) <----- Rearrange the exponent
\(-9.803 = \frac{t}{30.0yrs} (-0.6931)\) <----- Solve the natural logs
\(1.1414= \frac{t}{30.0yrs}\) <----- Divide both sides by -0.6931
\(42.4 yrs= t\) <----- Multiply both sides by 30.0 yrs

Explanation:
it turns out that an object increases as the square of it's speed.
Answer:
Explanation:
In all physical processes taking place in closed systems, the amount of change in kinetic energy is equal to the amount of change in potential energy. If the kinetic energy increases, the potential energy decreases, and vice-versa. this equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. so therfore stays the same as the object so it would speed up as well.

Arrange the gases from most dense to least dense at a given temperature and pressure.
Most dense
Least dense
Answer Bank
Ar
Ne
CO2
H
C12
Answer:
Arrange them in order of greatest to least Molar Mass to get most dense to least dense at a given temperature and pressure.
Explanation:
"Given Temperature and Pressure" just tells you that those two variables are being held constant. The Ideal Gas Law (PV = nRT) shows that n (the # of moles) and V (the volume) are variable still. To keep pressure constant, we need to increase the volume so that the force per area is the same which would unfortunately lower the density. The only way for a gas to have the greatest density would be to have the least average kinetic energy to keep the pressure constant at a smaller volume. This is because kinetic energy is equal to KE = 1/2 m v^2, where m is mass in kilograms and v is the velocity. IT IS CRUCIAL TO NOTE THAT ACCORDING TO KINETIC MOLECULAR THEORY, ALL GASES HAVE THE SAME AVG. KINETIC ENERGY WHEN AT THE SAME TEMPERATURE. So since the avg. KE is also constant across these answers due to the temp. being constant, our only way to decrease the velocity (the rate at which the particles are moving per second) and in turn the number of collisions (to repeat, a smaller number of collisions is desired because they are equal to the pressure that must maintained at a constant value at the smallest volume possible to achieve highest density possible) is to increase the molar mass. This is also pretty intutive for the other part of the issue: since Density is a broken heart (m/v), a higher molar mass would ensure a smaller pressure (due to decreased velocity) and smaller volume (due to constant pressure). Okay, now order the gases heaviest to lightest in terms of molar mass and you got your answer. Please gimme brainliest if this helped bc it took 15 minutes to type out. Hope this helped you! :D
Density is an intensive property as it does not depend on the quantity of the substances Whereas mass and volume are extensive property. The order of density is carbon dioxide>Neon >argon>carbon-12> hydrogen.
What is density?Density tells about the compactness of the substances, how much dense is the substances in other words. Object that is more denser than water they just sink in the water.
Mathematically,
Density of gas = Molar Mass of the gas ÷volume occupied by the given gases
Density is directly proportional to molar mass of the gases.
Molar mass of argon = 18g/mole
Molar mass of Neon = 20g/mole
Molar mass of carbon dioxide=44.01 g/mol
Molar mass of hydrogen=1g/mol
Molar mass of carbon-12=12g/mol
The order of gases from most dense to least dense at a given temperature and pressure is carbon dioxide>Neon >argon>carbon-12> hydrogen.
Therefore, the order of density is carbon dioxide>Neon >argon>carbon-12> hydrogen.

An isotope has a half-life of 12.5 years. How long must you wait for the radioactivity rate to decrease to 14.35% of its original value?
An isotope has a half-life of 12.5 years, you must wait for 36.5 years for the radioactivity rate to decrease to 14.35% of its original value
The amount of radioactive material decreases by half during each half-life. Therefore, if the radioactivity rate decreases to 14.35% of its original value, it means that the material has gone through a certain number of half-lives.
We can use the following formula to determine the number of half-lives:
n = log(1/2) / log(1 + r)
where n is the number of half-lives, r is the fraction of the original material remaining (in this case, 0.1435), and log represents the logarithm with base 10.
Plugging in the values, we get:
n = log(1/2) / log(1 + 0.1435) ≈ 2.92
This means that the material has gone through approximately 2.92 half-lives. Since the half-life is 12.5 years, the total time elapsed would be:
t = n x half-life = 2.92 x 12.5 years ≈ 36.5 years
Therefore, you would need to wait for approximately 36.5 years for the radioactivity rate to decrease to 14.35% of its original value.

The statement which is true for ideal gases at stp conditions is: one mole of an ideal gas has a volume of 22.4L which is also known as standard molar volume.
What are ideal gases?
The term ideal gas refers to a virtual gas composed of molecules that obey some rules.
Ideal gas molecules do not attract or repel each other. The only interactions between ideal gas molecules are elastic collisions when they collide with each other or with the walls of the container.
Ideal gas molecules take up no volume by themselves. Gases occupy volume as their molecules expand into large regions of space, but ideal gas molecules are approximated as point particles that have no volume of their own.
What is the molar form of the ideal gas law?
Ideal gas pressure, P, volume V, and temperature T are related by a simple equation called the ideal gas law. The simplicity of this relationship is an important reason why we usually treat gas as ideal unless there is another reason.
PV=nRT
