Answer:
Explanation:
Both points on a wave oscillate in directions that are perpendicular to the wave's advanced path, resulting in a transverse wave motion. Sea surface ripples, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.
Their frequency and amplitude are related to the amount of energy they bear. The more energy, the higher the frequency, and the more energy, the higher the amplitude. With the activity Investigating waves and electricity, you will create these patterns on your own.
Particles in the medium vibrate to and from in a direction perpendicular to the direction of energy transport in transverse waves.

When the pressure is in a certain gas cylinder with a volume of 4.50 L reaches 500atm, the cylinder is likely to explode. If this cylinder contains 40.0 moles of argon at 25.0°C, is it on the verge of exploding? Calculate the pressure
Answers
Answer:
The cylinder is nit on the verge of exploding.
Explanation:
Temperature= 25.0°C
The conversion of T(°C) to T(K) is shown below:
T(K) = T(°C)+ 273.15
So,
T=(25.0 + 273.15) K = 298.15 K
Volume= 4.50 L
Moles= 40.0 mol
Using ideal gas equation as:
PV = nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is gas constant having value = 0.0821 Latm/ K. mol x 298.15 K
⇔ P= 217.58 atm
Pressure limit = 500 atm .

Answers
Answer:
135.16 mL
Explanation:
From the question,
Applying,
PV/T = P'V'/T'.................... Equation 1
Where P = Initial pressure of the gas, V = Initial volume of the gas, T = Initial Temperature of the gas in Kelvin, P' = Final pressure of the gas, V' = Final Volume of the gas, T' = Final temperature of the gas in Kelvin.
Make V' the subject of the equation
V' = PVT'/TP'................... Equation 2
Given: P = 600 torr, V = 115 mL, T = 50 °C = (50+273) K = 323 K, T' = 75 °C = (75+273) K = 348 K, P' = 550 torr
Substitute these values into equation 2
V' = (600×115×348)/(323×550)
V' = 24012000/117650
V' = 135.16 mL

help asap show work | a gas with a volume of 13L at a pressure of 197 kPA is allowed to expand to a volume of 23L. what is the pressure of the container if the temperature remains constant
Answers
Answer:
111 kPaExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
We have
[tex]P_2 = \frac{13 \times 197000}{23} = \frac{2561000}{23} \\ = 111347.826...[/tex]
We have the final answer as

if the hydrogen ion concentration [H+] in a solution is 1.87 x 10^-11M what is the [OH-]
Answers
By using pH formula, the concentration of hydroxyl ion [OH-] will be 5.3 ×[tex]10^{-4}[/tex] M.
What is pH?
The pH scale is a measurement of hydrogen ion concentration that is used to determine the acidity as well as alkalinity of a solution.
Calculation of [OH-] by using formula of pH.
Given data:
[H+] = 1.87 x [tex]10^{-11} M[/tex]
[OH-] = ?
Calculation of [OH-] is shown below:
It can be calculated by using the formula:
pH = -log [H+]
Put the value of concentration of hydrogen ion [H+] in above formula.
pH = -log (1.87 x [tex]10^{-11} M[/tex])
pH = -log (1.87) -log ( [tex]10^{-11} M[/tex])
pH = -0.27 +11
pH = 10.73
Now, use the formula, pH +pOH = 14
pOH = 14 - pH
pOH = 14 - 10.73
pOH = 3.27
Now, use formula pOH = -log [OH-]
[OH-] = [tex]10^{-pOH}[/tex]
[OH-] = [tex]10^{-3.27}[/tex]
[OH-] = 5.3 ×[tex]10^{-4}[/tex] M
Therefore, the concentration of hydroxyl ion [OH-] will be 5.3 ×[tex]10^{-4}[/tex] M.
