AI Thread Summary
A physics project is required for finals, where students must create a simple machine measuring 4 feet by 5 feet with seven processes and an objective. The project can involve various physics concepts, such as speed, force, and gravity. Suggestions include using experiments like wave superposition in water or conservation of momentum to fulfill the requirements. The challenge lies in integrating these concepts into a cohesive design while meeting the project's specifications. Assistance is sought due to the late assignment and difficulty in understanding the physics involved.

Homework Statement


Hi guys! Our finals are coming up and our Physics professor is asking us to create a project which is equivalent to our final quiz and if selected by the Department head we would get a 100% in our subject for the term.

Our professor specified that it has to be a simple machine putting out simple output. It has to be 4feet by 5 feet with 7 processes and an objective. Please any suggestions would be a great help since it was given to us late and the deadline is on August 30th. I hope someone can help.

Can you give any more detail about what this is supposed to do?
 
Hi there madmike159! Um well our professor just specified that we can create pretty much anything that is involved with Physics or its subtopics. Just as long as it is 5 feet high and 4 feet wide and has 7 processes...for example let's say a ball rolls down an incline and hits a button to launch another ball into the air so on and so forth...something like that where we can explain speed, force, gravity etc...the thing is I am just not good at Physics or things like this at all. My groupmates are no help and I really need the grade. So if you could so kindly suggest something where maybe you have created a project before where you have the design still and the procedures and list of materials I would be so grateful. I am currently looking online but what makes the project difficult is that it has to have 7 processes and of course its height and length required. :( Please help me.
 
You could think of 7 basic experiment that you should have been shown in physics. Of the top of my head you could have

-Wave superposition in water
-Wave interaction in light (diffraction grating)
-Light discharging a charged metal surface
-Conservation of momentum

I'm sure you can pick out a few more from a textbook. I wouldn't worry about the logistics of a machine that does all this. From what you have said it sounds almost like a box full of experiments really. The first 3 on my list are also related, so you could find more related experiments.
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
