<u><em>Answer:</em></u>
Destructive interference
<u><em>Explanation:</em></u>
<u>Interference</u> is a term used to refer to the combination of two waves or their overlap
<u>There are two types of interference:</u>
<u>1- Constructive interference:</u> This happens when the waves overlap/combine to produce a resultant wave with a larger displacement
<u>2- Destructive interference:</u> This happens when the waves overlap/combine to produce a resultant wave with a smaller displacement
Hope this helps :)
Total displacement along the length of mountain is given as
L = 235 m
angle of mountain with horizontal = 35 degree
now we will have horizontal displacement as
x = L cos35
x = 235 cos35 = 192.5 m
similarly for vertical displacement we can say
y = L sin35
y = 235 sin35 = 134.8 m
The acceleration of gravity on or near the Earth's surface is 9.8 m/s² downward.
Is that right ? I don't hear any objection, so I'll assume that it is.
That means that during every second that gravity is the only force on an object,
the object either gains 9.8m/s of downward speed, or it loses 9.8m/s of upward
speed. (The same thing.)
If the rock starts out going up at 14.2 m/s, and loses 9.8 m/s of upward speed
every second, it runs out of upward gas in (14.2/9.8) = <em>1.449 seconds</em> (rounded)
At that point, since it has no more upward speed, it can't go any higher. Right ?
