1. Homework Statement This is the sample answer to the circuit they ask to draw. I get the comparators, the inverter and the Gate. That’s all clear. Then they wanted a switch that needs to be used to end the sound alarm, regardless of comparator output. I assume this the box labelled M...

Ahhhh regarding d) Area under the Graph in fig.4 is Work. But the graph is not linear. Can I ignore that? Then it would be 0.5 x 24m x 2476N = 29712Nm or J. If I say at her highest point EGrav is max, I can say 29712J = m x g x h, giving me a height of 48.5m. But the curve is not linear...

Sorry I am still stuck. The more I look at it the more confused I am. What is Angle β?

The acceleration has halved too?

Sorry but I don't know how I would calculate that. Sorry if it seems easy, but I have 0 knowledge coming into this.

Ok thanks. I know what you mean. There is loads of vague / weird / incorrect wording in my opinion. Was my attempt at measuring correct though? Any idea about d)? Thanks :)

Thank you. First question posted under homework help, hope I used the right format. :)

Homework Statement As on the paper below: Homework Equations Suvat? The Attempt at a Solution As on my paper a) I think I got the acceleration correct by measuring the angle, halving the angle to get the force upwards by each rope. Or is that the wrong answer? b) Should be half as it’s...

hi, I’m a med school applicant that has a deficiency in physics to be admitted. So I have about two weeks to learn high school physics and do the exam. Hope this is the right place to get help with questions I am stuck with.
