Q2. Blue light has a wavelength of 470 nm and a frequency of 6.30 ~ 1014 Hz
Calculate the velocity of blue light.

come closer and become far apart and become steam/gas

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

technology is the application of the knowledge gained by science.
