Send wave from your location to the object and wait until echo is back.
Measure the time taken.
If you know the speed of wave (say sound wave), than just multiply by half time taken wave to return
b..a harmless organism imitating the look of a harmful organism
Explanation:
A harmless organism imitating the look of a harmful organism is one example of mimicry that enables prey species avoid predation.
Prey are smaller and less harmful organisms often hunted by larger organisms usually carnivores.
Mimicry is a form of evolutionary adaptation process in which two organisms of the same specie or different species tends to look alike.
It is a subtle defense mechanism developed by organism over an extended period of time.

Explanation:
Answer:
The magnitude of the magnetic field halfway between the wires is 3.0 x 10⁻⁵ T.
Explanation:
Given;
distance half way between the parallel wires, r = ¹/₂ (40 cm) = 20 cm = 0.2 m
current carried in opposite direction, I₁ and I₂ = 10 A and 20 A respectively
The magnitude of the magnetic field halfway between the wires can be calculated as;

where;
B is magnitude of the magnetic field halfway between the wires
I₁ is current in the first wire
I₂ is current the second wire
μ₀ is permeability of free space
r is distance half way between the wires

Therefore, the magnitude of the magnetic field halfway between the wires is 3.0 x 10⁻⁵ T.
