Basic com doubt
And yes you’re absolutely correct about a net gravitational force downwards hence momentum is not conserved in y direction across long timespan, but for dt seconds before and after collision we can approximate and assume it to be conserved for that infinitely small interval of time

Basic com doubt
And upwards and downwards impulsive forces cancel out giving us a net zero force just dt seconds before and after the collision

Basic com doubt
Since impulsive forces are very large compared to gravitational force the downward gravitational force can be neglected compared to the large downward impulsive force acting on the bullet wood system

Basic com doubt
@Gaurav no it will work just before and just after the collision because at the time of collision two opposite impulsive forces will be acting on the wood and bullet that will cancel each other out

why does Earth rotate?
But as sir said all these are just our assumptions and we can’t answer everything

why does Earth rotate?
I don’t know if my answer will satisfy you but when nebula gets condensed and star systems get formed protoplanets, dust and debris smash into each other most of which are oblique collisions cause head on collision are rare since a lot of lining up is required, hence these oblique collisions add up and give the rotation to newly forming planets and after that since space is complete vacuum you don’t have air drag and stuff to stop the rotation

You don’t replace the battery with EMF voltage but rather the Voltage across the external resistor, cause you have to take into account the amount of voltage dropped across and used by internal resistance

Thermochemistry ( enthalpy and heat )
Ok got it sir @iTeachChem, I was just wondering that maybe constant pressure had some implications at a higher level concept or something, I think my doubt has been clarified, thank you

Thermochemistry ( enthalpy and heat )
So does that mean, that if we specify some conditions, we observe that the value of heat becomes associated with just the ideas of initial and final states and consequently we acknowledged the fact and said enthalpy that is heat at constant pressure is state function because we observe it to be so,there is no how it’s just what it is in nature, did I get it right or I missed something
