Answer:
displacement = 2 m west
Explanation:
The displacement of an object is a vector connecting the final point of the motion of the object to the initial point, and its magnitude is equal to the length of the vector. So the magnitude of the displacement is basically the distance (measured in a straight line) between the final point and the starting point.
In this problem, we have:
- initial position of the acorn: 0 m
- final position of the acorn: 2 m west
So, the displacement has a magnitude of
d = 2 m - 0 m = 2 m
And the direction is west, since the final position is west compared to the initial position.

Answer:
answer the correct is B
Explanation:
For the interference phenomenon to occur, some conditions must be met.
* You must have a light in phase and coherent, for this you can for a light from an incandescent source through a single slit, the light that comes out is coherent
* This light must strike two slits
* the light that passes through the slits must hit a distant screen and be able to see the phenomenon of constructive interference
when examining the different answer the correct one is B
<h3><u>Answer;</u></h3>
18 Joules
<h3><u>Explanation;</u></h3>
- <em><u>Work is the measures the transfer of energy when an object moves over a given distance.</u></em>
- Work is therefore given by; Force × distance
Force =36 Newtons
Distance = 0.5 meters
- Hence; <em>work = 36 N × 0.5 N</em>
<em> = 18 Joules </em>
