Professor, why do we ignore atmospheric pressure when explaining hydraulic lift? (While saying the force acting on the piston of larger area)
@lecturesbywalterlewin.they9259

your body does not experience atm pressure as that pressure is also inside your body. Thus if you go 10 m onder water your body only experiences the hydraulic presssure

@@lecturesbywalterlewin.they9259 Sorry, I mean while calculating the force acting on the car , we're not considering the atmospheric pressure (hydraulic lift diagram) F1/A1= F2/A2 F2= F1A2/A1 Here F2 doesn't include the initial pressure before pressing the piston of smaller area.. Maybe I am wrong.

Suppose there is a spacecraft travelling with the speed of light ,now at that time its mass and also energy required to move it will become infinite.So according to Einstein's special theory of relativity [e=mc²],which tells us that mass and energy are both interchangeable,so if I change the mass of spacecraft travelling with the speed of light into energy that is then used to fuel it. -If I apply this concept then is it move with superluminal speed?

As far as I understand there have been debates on this topic for hundreds of years. I heard this question for the first time more than 10 years ago and since then I didn’t knew who to believe. All the experiments I saw were not convincing enough and I've began to think that perhaps this was just nonsense. I really liked your explanation. It’s still very difficult to imagine what exactly charge, voltage, current and resistance are, but the further, the closer my understanding to reality. Thank you very much for the enlightenment!
