How are a wave's energy and the wave's amplitude related?

Physics
1 answer:
dem82 [27]2 years ago
7 0
Answer:
Energy is proportional to the square of the amplitude

Explanation:
The energy of a certain wave is defined using its magnitude.
The two quantities are related directly. This means that as the amplitude of the wave increases, its energy increases and vice versa.

Energy is directly proportional to the square of the magnitude of the wave. This means that:
If we have new amplitude = 2 * old amplitude
We will have new energy = (2)² * old energy = 4 * old energy

Hope this helps :)

Ede4ka [16]

Answer:

H = 50.5 m

Explanation:

As we know by work energy theorem that work done by all forces is equal to change in kinetic energy

So we know that

W_f + W_g = \frac{1]{2}mv_f^2 - \frac{1}{2}mv_i^2

so we know that

W_f = -4000 J

v_f = 30 m/s

v_i = 2 m/s

m = 86 kg

now we have

mgH - 4000 = \frac{1}{2}(86)(30^2 - 2^2)

86(9.81)(H) - 4000 = 43(900 - 4)

H = 50.5 m

The phosphorus cycle is important to ecosystems. Choose all of these statements that are true concerning the phosphorus cycle.
Lesechka [4]

Answer:

The largest reservoir of phosphorous is sedimentary rock.

Major sources of phosphorous to aquatic ecosystems are fertilizer runoff, sewage leaks, and industrial wastes.

Eccess phosphorous can lead to eutrophication

Explanation:

Phosphorus come from different sources such as aquatic ecosystems and fertilizers used for plants. When these substances containing phosphorus and those from industrial wastes find their way into water bodies, they tend to cause eutrophication, which is the natural enrichment of water bodies.  

Also, it is known that a very small portion of phosphoric acid contribute to acid rain in the atmosphere.

At time t = 1, a particle is located at position (x, y) = (5, 2). If it moves in the velocity field F(x, y) = xy − 1, y2 − 11 fi
Amanda [17]

Answer:

Its approx location is (5.18,1.9)

Explanation:

Using F( 5,2) = ( xy-1, y²-11)

= ( 5*2-¹, 2²-11)

= (9,-5)

= so at point t=1.02

(5,2)+(1.02-1)*(9,-5)

(5,2)+( 0.02)*(9,-5)

(5+0.18, 2-0.1)

= ( 5.18, 1.9)
