Answer:
Range of R is from 4.81MΩ to 36.54 MΩ
Explanation:
Capacitance(C) = 0.520 µF = 0.52 x 10^(-6) F
Time constant = from 2.5 to 19 seconds
In RC circuits, time constant is;
r = RC
Where R is the range (in MΩ)
And r is time constant
Thus,
R = r/c
So minimum range will be at 2.5seconds.
Thus; Rmin = 2.5/(0.52 x 10^(-6)) = 4.81 x 10^(6) Ω = 4.81MΩ
Rmax = 19/(0.52 x 10^(-6)) = 36.54 x 10^(6) Ω = 36.54 MΩ
Answer:
255 [m].
Explanation:
1) the formula is (d - requred distance, V₀ - initial velocity, t - elapsed time, a - deceleration):
2) according to the formula above the required distance is:
d=10*30-0.5*0.1*900=300-45=255 [m].
