Hi there, so for this problem, we need to calculate the required resistance for the flash tube.
00:07
And then the first step to do this is to determine the time corresponds to one millimeter of motion.
00:16
Now the bullet is, as we are given for this, is traveling as 600 meters per second.
00:23
And then the distance is 0 .001 meters.
00:30
Then the time is just the distance divided by the velocity.
00:37
So that will be 0 .001 divided by 600.
00:45
So this will give us a value of 1 .67 times 10 to the minus 6.
00:50
Okay, and then this will be in seconds.
00:54
Now, in order to find the resistance, we can use the fat, that the time constant is the product between the resistance and the capacitance...
