We assume

(acceleration is constant. We apply the equation

where s is the distance to stop

. We find the acceleration from this equation

We know the acceleration, thus we find the distance necesssary to stop when initial speed is

I think the answer is 8.2 mm
It is Amperes(A), so the answer is A
Answer:
he diameter of the oil slick is 2523 m
Explanation:
given information?
V = 1 L = 1000 cm³ = 0.001 m³
h = 2 x 10⁻¹⁰ m
first we have to find the radius using the following equation
V = πr²h
r = √V/(πh)
= √(0.001)/(π x 2 x 10⁻¹⁰ )
= 1261.56 m
now, we can calculate the diameter of the oil slick
d = 2r
= 2 (1261.56)
= 2523 m
