I added a picture below. Thank you.

https://ibb.co/jSf6Ka There is a drawing of the setup at the link. I don't have access to the equipment right now. The H2 gets up used up quickly to run a motor. Not much time for the gas to escape.

Can you tell me why? Would it hurt to add the fluid pressure too?

Hello! H2 does rise in the column. If we continue generating H2, it escapes as bubbles. However, we stop hydrolysis when the gas starts to bubble. It also raises the height of the water by 16 cm (corresponding to 16 mL H2 generated). Yes, I am attempting to use Henry's law. There is no lid on...

Hey there, I assumed by "lost" they meant how much gas dissolved in the water. But yes, water seals the gas. The gas also displaces the water by 16 ml as it is generated via electrolysis of water. The water appears to remain at 30 ml (which when measured with a ruler corresponds to 30 cm on...

Homework Statement I need to find the amount of H2 being lost to water by being stored underneath a column of water. About 16 mL of H2 is made and it displaces the column by 16 cm. However the total amount of water is 30 ml/30 cm. I'm not sure which relationship to use to find the pressure of...

Ohhh that's so clever! I worked it out to myself on paper, makes sense. Thank you for all your help! :)*

Hi again, I looked at my diagrams and noticed a lot of the mistakes >.> Fnet has constant magnitude so the vector should always be the same length. Same with gravity. Here's my thinking: At the top of the circle, N is smaller than mg, if not zero. At the right, mg doesn't even contribute to the...

Hi, the question says the person is riding the Ferris wheel so I assume Fnet is not zero. It would appear that Fseat is biggest at 4:30. Do I finally have a solution?? [emoji102]

I just don't get it. At the top: Fnet = mg - N; N = mg - Fnet Bottom: Fnet = N - mg; N = Fnet + mg 3 o' clock: Fnetx = Nsin(theta); Fnety = mg - Ncos(theta) ? 4:30: same as above, different angles?? There are no given values. So how do I determine the answer just from this?

Yeah, I'm trying to use all this info, but I can't come up with a solution = If velocity, radius, and mass are constant then acceleration and centripetal force must be as well? Would it be the 4:30 position because the net force is pointing at an angle to the centre of the circle, gravity's...

Homework Statement What is the maximum reaction force exerted by a seat on the passenger of a ferris wheel? There's a diagram showing the seat at 6 o'clock, 12, 3, and 4:30... on a 12 hour clock. Homework Equations N/A The Attempt at a Solution I guess the reaction force is the normal force...

Ok thank you!
