What is the Direction of x Using the Right Hand Rule?

AI Thread Summary
The discussion revolves around determining the direction of x using the right hand rule, given that z is east and y is south. The initial confusion arises from the incorrect assumption that x could also be south, which is already defined by y. After clarification, it is established that x corresponds to the upward direction. The correct application of the right hand rule confirms that x is indeed up. This conclusion resolves the initial uncertainty regarding the orientation of x.

The Attempt at a Solution


using the right hand rule the answer i got is south is this correct?

that can't be right because y is already south

you know z=east so that -z=west and y=south so that -y=north so what else is left for x?

really sorry i meant up is that correct?

Yes. Rotating y into z gives x for your thumb.
 

Thread 'Rolling without slipping on a curved surface'

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 .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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...
