AI Thread Summary
To calculate the number of electrons leaving the battery's negative terminal in 3 seconds with a current of 2 A, first recognize that 1 Ampere equals 1 Coulomb per second. Therefore, in 3 seconds, the total charge is 2 A x 3 s = 6 Coulombs. Given that the charge of a single electron is approximately 1.602 x 10^-19 C, the number of electrons can be calculated by dividing the total charge by the charge of one electron. This results in approximately 3.75 x 10^19 electrons leaving the battery in that time frame. Understanding these principles is crucial for accurately calculating electron flow in electrical circuits.

i was stuck on this equation if a current of 2 A flows through a lamp when it is connected by copper wire of cross-sectional area 1 mm2 to the terminals of a battery. how many electrons will leave the negative terminal of the battery in 3 seconds? (obiviously the charge of electrons is e=1.602*10–19 C.

Right. An Ampere is one Coulomb of charge per second. How many electrons make up one Coulomb?
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
