Answer:
rapid diffusion of gas throughout the system
Explanation:
b. amps/division
c. seconds/division
d. ohms/divisionthe horizontal sweep of an oscilloscope is rated in seconds/division.
Answer:
Second division
Explanation:
[H3O+] is just the same with [H+]. There are quite a few relationships between [H+] and [OH−] ions. And because there is a large range of number between 10 to 10-15 M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+ ][OH- ] = 10-14.
b temperature and pressure only
c. volume and temperature only
d. temperature, pressure, and volume
The combined gas law relates temperature, pressure, and volume and can be represented by the equation P1V1 / T1 = P2V2 / T2.
The combined gas law relates temperature, pressure, and volume. It states that the product of the initial pressure, volume, and temperature of a gas is equal to the product of the final pressure, volume, and temperature. This law can be represented by the equation:
P1V1 / T1 = P2V2 / T2
where P1 and P2 are the initial and final pressures, V1 and V2 are the initial and final volumes, and T1 and T2 are the initial and final temperatures.

Answer:
2 m/ s2.
Explanation:
2 m/ s2.
Acceleration = (final speed - initial speed) divided by total time taken.
= (25–15) divided by 5
10 divided by 5 gives an acceleration of 2 metres per second per second.
The material that would absorb the most sound is Heavy curtains (Option A)
The effectiveness of a material in absorbing sound is typically measured by its coefficient of absorption.
The coefficient of absorption ranges from;
Based on the coefficient of absorption for each material listed, the best choice for sound absorption would be Heavy curtains.
Heavy curtains are often designed with sound-absorbing properties, and they can have a coefficient of absorption higher than other materials like wood, concrete, or carpet.
The ranking of the absorption of the materials are;
Heavy curtains (0.5) > Carpet (0.2) > Wood (0.05) > Concrete (0.02)
