Answer:
Resistance in the flash tube,
Explanation:
It is given that,
Speed of the bullet, v = 500 m/s
Distance between one RC constant, d = 1 mm = 0.001 m
Capacitance,
The time constant of RC circuit is given by :
R is the resistance in the flash tube
..........(1)
Speed of the bullet is given by total distance divided by total time taken as :
Equation (1) becomes :
So, the resistance in the flash tube is . Hence, this is the required solution.
Answer:
The smallest distance the student that the student could be possibly be from the starting point is 6.5 meters.
Explanation:
For 2 quantities A and B represented as
and
The sum is represented as
For the the values given to us the sum is calculated as
Now the since the uncertainity inthe sum is
The closest possible distance at which the student can be is obtained by taking the negative sign in the uncertainity
Thus closest distance equals meters
