The example of walking on sphere is just to understand why something that is curved may seem straight. The curvature of space is real and that is what we call Gravity. Near any massive body, space is curved towards center and hence any free object will move towards center, and we call it freely...
No, I thought u were talking about frictional force in part c. For part b frictional force would be Us * N. And since the book is not moving horizontally, it means the horizontal forces are balanced. So N equals P.
Also there is no need of considering max static friction in this problem. Hope...
U r getting confused. All your calculations are correct. U just have to understand them fundamentally. Think about whether the answer in c should be compared with b or with a?
If u r just dropping the magnet then the speed of the magnet is not constant throughout the drop. It will be less in first half and as compared to second half. So the rate of change of magnetic flux is not the same through the two coils(assuming the coils are one above the other) . Apart from...
Have joined this forum out of my interest to discuss physics. I come from engineering background and current in IT. Very passionate about physics for discussions, teaching and learning (There is always something new to learn) . I find this site very addictive and am looking forward to interact...
If something is not rotating around its axis then any distant observer should see the same side of the object irrespective of the object's revolution
That is not the case with moon as seen from the Sun or the person on merry go round as seen from someone outside.
While walking if u take a...
Yes exactly. And for the second part you can find the angle taking S as 200 in the same range formula and finding the angle. You may get a range of angles with 45 deg as the mid point of that range
