Seemingly easy problem having to do with current?

AI Thread Summary
To calculate the current during a lightning strike, the formula used is current = charge/time. The charge is given as 2.5 C and the time should be converted correctly to seconds, which is 0.020 ms or 0.00002 s, not 0.0002 ms. Using the correct values, the current is calculated as 125,000 A. The initial confusion stemmed from a miscalculation of the time unit. Correcting this leads to the accurate determination of the current.

Homework Statement



In a typical lightning strike, 2.5 C flows from cloud to ground in .020 ms. What is the current during the strike?

Homework Equations



I've been doing 2.5 C / .0002 s = 12,500. However, this is not right.

The Attempt at a Solution



Am I using the wrong formua? This problem seems so easy I don't know where I'm messing up.

Hello csimon current =charge/time so it seems you are using the correct formula.The time is 0.02ms=0.00002s not 0.0002ms
 

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}...
