Answer: 3.75 m
Explanation:
5 squirts in 1 second
So, 1 squirt in 1/5 second which is 0.2 second.
The difference in timing of two consecutive squirt is 0.2 second, so
time (t) = 0.2 s.
speed (s) = 15 m/s
Distance of separation (d) = ?
Now, formula for distance is
d = s × t
d = 15 × 0.2
d = 3.75 m
The array of colors observed when viewing films of soap are caused by the interference, and from the reflections of light from two nearby surfaces (outer surface and inner surface). Among the choices, the closest answer would be B. reflection, refraction, and interference.
When scientific work can be duplicated it is proves a hypothesis is reliable.
For the record, in science, hypotheses can never be proven correct, and they always require evaluation. Even if a hypothesis still holds after being tested many times, it will always remain open to question.
This region is called the magnetic field. Any object within the magnetic field will experience a force that is caused by the source (e.g. magnet)
