The question is incomplete.
This is the complete question:
Consider equimolar samples of different ideal gases at the same volume and temperature. Gas A has a higher molar mass than gas B.
Compare the pressures. Compare the rms speeds. Compare the average kinetic energies.
Answer:
pressure: A = B
RMS: A < B
kinetic energies: A = B
Explanation:
1) Pressure:
You can deal with this part of the question on the basis of Avogaro's principle which stated that equal volumes of gases at same temperature and pressure have the same number of particles (molecules).
Also, kinetic theory of gases postulates that the particles of gas are quited separated and in consequence the volume occupied by the particles of a gas is meaningless and does not influence the total volume occupied by a fixed number of particles.
Also, you can use the equation of ideal gases pV = nRT, from which p = nRT/V. if n, T, and V are fixed, then p is fixed.
The three approaches leads to the same conclusion.
Then, pressure of gas A is equal to pressure of gas B.
2) RMS
RMS stands for root mean square speed.
It is the room mean square speed of the particles of a gas.
the RMS is related with the temperature of the gas and the molar mass per this equation:
RMS = √(3RT/M), where R is the universal constant of gases, T is the absolute temperature and M is the molar mass.
Then, the greater the molar mass, the lower the RMS, which permits you conclude that the RMS of gas A is less than the RMS of the gas B.
3) kinetic energy
Temperature is a measure of the kinetic energy.
Equal temperatures of the gas means equal kinetic energies.
The Kinetic Molecular Theory states that the average energy of molecules is proportional to absolute temperature.
So, you conclude that the same amount of gases, at the same temperature, contain equal kinetic energies.

the three numbers are in the ratio 2 : 3 : 4. the sum of their cubes is 33957. find the numbers.
Answer:
14, 21 and 28
Explanation:
2 : 3 : 4 - find the total of the numbers in the ratio cubed
2³ + 3³ + 4³ = 99 - divide 33957 by the total (99)
33957 ÷ 99 = 343 - cube root 343
∛343 = 7
This means we have to multiply each number in the ratio by 7 to find the answers:
2 × 7 = 14, 3 × 7 = 21, 4 × 7 = 28
Answer: 14, 21, and 28
Check:
14³ = 2744, 21³ = 9261 and 28³ = 21952. 2744 + 9261 + 21952 = 33957

how are payroll taxes different from personal income taxes brainly
Answer:
They pay for specific social programs rather than general government activities.
Explanation:
Individual Income Taxes
An individual income tax (or personal income tax) is levied on the wages, salaries, investments, or other forms of income an individual or household earns.
Payroll taxes are taxes paid on the wages and salaries of employees to finance social insurance programs. Most taxpayers will be familiar with payroll taxes from looking at their paystub's at the end of each pay period, where the amount of payroll tax withheld by their employer from their income is clearly listed.

In basketball, hang time is the time that both of your feet are off the ground during a jump. The equation for hang time is t = 2 (StartFraction 2 h Over 32 EndFraction) Superscript one-half , where t is the time in seconds, and h is the height of the jump, in feet. Player 1 had a hang time of 0.9 s. Player 2 had a hang time of 0.8 s. To the nearest inch, how much higher did Player 1 jump than Player 2? in.
Answer:
8in
Explanation:
edge 2020
The amount of height that player 1 jumped higher than player 2 to the nearest inch is; 8 inches
How to substitute values into an equationWe are given the hang time equation as;
t = 2(2h/32)^(½)
Where;
h is height of jump
Hang time of player 1 = 0.9 s
Hang time of player 2 = 0.8 s
Let's make h the subject of the hang time equation to get;
h = 2t²
For player 1;
h1 = 2(0.9)²
h1 = 3.24 ft
Converting to inches gives;
h1 = 38.88 inches
For player 2;
h2 = 2(0.8)²
h2 = 2.55 ft
Converting to inches gives
h2 = 30.72 inches
Difference in jump height = h1 - h2
Difference in jump height = 38.88 - 30.72
Difference in jump height ≈ 8 inches

schools often use concrete rewards to increase adaptive behaviors. how might this be a disadvantage for students intrinsically motivated to learn?
Answer:
Intrinsic motivation is a type of motivation that an individual has that comes internally, that is, the individual does a specific task or activity mainly because he or she enjoys it or wants to learn from it. In this scenario, a student studies or behaves properly because he or she is motivated to become better instead of doing it because he or she will receive a reward or a good appraisal from the teacher or parents.

Explanation:just did on edge
By digging snow tunnels from their shelters to the tunnel.
What is tunnel?When you're gazing straight ahead, your peripheral vision, also known as side vision, is what you perceive on the edges of your visual field.
When this peripheral vision is compromised, tunnel vision results. If this occurs, you won't be able to see anything unless you are directly facing it.
Two different kinds of photoreceptors, or light-sensing cells, in the retina, called rods and cones, are the primary culprits in this kind of vision loss. By identifying light and communicating information to the brain, the retina aids with vision.
A brain injury may also result in tunnel vision. For instance, even if there is no injury to the eye itself, a stroke can harm the brain's visual system and result in tunnel vision.
