Scientific Notation
I think order of magnitude is for finding the rough estimate, by considering only power of 10
if it goes above 5, then it is closer to the next power of 10 than the previous one during estimation.
eg 4.9*10^4 is roughly 10^4 but 5.1 x 10^4 is roughly 10^5 as its closer to 10^5 than 10^4.

Thank you so much!
So the main thing was that since the rod is leaning on the box, it's velocity component in the direction of motion of box is same as the velocity of the box.
Sorry for not closing this thread earlier.

Ok, you could also see the photo I had sent earlier it's done by the same way of assuming 1 photon

They're asking for ratio of number of photons so if you assumed 1 photon was absorbed then the number that is emitted will give the ratio

Look at the photo you sent
In the Ea formula there was n that is number of photons but in the next step it's not there as you assumed it's 1

But you assumed one quanta is absorbed so the number of quanta emitted will just be the ratio right

Yeah you got the answer as 508/1000 which is right

Not there in our module either, just our teacher gave it during problem solving so that it doesn't take too long to calculate

sign convention in 1D motion
Thank you so much!
Even if the speed is twice, shouldn't the velocities still be in the opposite directions as it's given in the question that the balls move in the opposite direction? We would have to put in values for velocity not speed in the equations
Also, is it right to take g as always negative, for example s = -½gt²? (In solutions, I've seen g being switched from positive to negative depending on direction of velocity)
