<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 :)

Two or more waves combining to produce a wave with a smaller displacement is called Destructive interference.


Explanation:

The interference of 2 waves of equal frequency and opposite section, leading to their cancellation wherever the negative displacement of 1 perpetually coincides with the positive displacement of the opposite.

In harmful interference, the crest of 1 wave meets the trough of another, and therefore the result's a lower total amplitude.

harkovskaia [24]
So we want to know what is the magnitude of the horizontal component of acceleration ah if we know that the overall acceleration a=12 m/s^2 and the angle of overall acceleration and the horizontal acceleration is α=50°. We know that ah=a*cosα. So now it isn't hard to get the horizontal component: ah=12*cos50=12*0.64=7.71 m/s^2. So the correct answer is ah=7.71 m/s^2.

A cheetah can run at 105 feet per second, but only for 7 seconds, at which time the animal must stop and rest. A fully rested ch
shepuryov [24]

Answer:

5 seconds

Explanation:

The straight line distance between (0, 0) and the antelope's position (x, y) at time t can be found using distance formula:

d² = x² + y²

d² = (-39 + 40t)² + (228 + 30t)²

d² = 1521 - 3120t + 1600t² + 51984 + 13680t + 900t²

d² = 53505 + 10560t + 2500t²

The cheetah can run a total distance of:

105 * 7 = 735

The time t at this distance is:

735² = 53505 + 10560t + 2500t²

540225 = 53505 + 10560t + 2500t²

0 = -486720 + 10560t + 2500t²

0 = -24336 + 528t + 125t²

t = 12, -16.224

t can't be negative, so t = 12.

Therefore, the cheetah can wait 5 seconds before it has to start running.

A soccer player runs up behind a 0.450-kg soccer ball traveling at 3.20 m/s and kicks it in the same direction as it is moving,
NISA [10]

To develop this problem it is necessary to use the concepts related to Impulse.

The impulse is defined as the change in velocity at the rate of mass, that is

L = m\Delta V,

Where,

m = Mass

\Delta V = Change in Velocity

This change in velocity can be expressed as,

L = m(v_2-v_1)

L = 0.45*(12.8 - 3.2)

L = 0.45*9.6

L= 4.32 Kg.m/s

Therefore the magnitude of the impulse is 4.32 Kg.m/s

Jason uses a lens with focal length of 10.0 cm as a magnifier by holding it right up to his eye. he is observing an object that
Svetlanka [38]

Answer:

3.5

Explanation:

The angular magnification, M = 1 + 25cm/f  where f = focal length = 10.0 cm

M = 1 + 25cm/f

= 1 + 25cm/10.0 cm

= 1 + 2.5

= 3.5
