I think is True! Is the best answer. Because the trumpet it make them sounds like the lips with the musician and it vibrate.
Answer: W = 11340J
Explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
So this is the Formula: Power = Work / Time.
<u>Step 1:</u><em><u> Find the Formula</u></em>
P = W / T
<em><u>
</u></em>
<u>Step 2: </u><u><em>Make W the subject of the equation.</em></u>
W = PT
<u>Step 3:</u><u> </u><u><em>Given.</em></u>
P = 270 Watts, T = 42 seconds
<u>Step 4:</u><u><em> Substitute these values into equation 2
.</em></u>
W = 270(42)
<u>Step 5:</u><u> </u><u><em>Simplify.</em></u>
W = 11340J
The amount of work done was 11340.

Gravitational force decreases with increasing distance. So it decreases!
<span>A photon is characterized by either a wavelength, denoted by λ or equivalently an energy, denoted by E. There is an inverse relationship between the energy of a photon (E) and the wavelength of the light (λ) given by the equation:
E=hc/λ
E=hc/λ
where h is Planck's constant and c is the speed of light. The value of these and other commonly used constants is given in the constants page.
h = 6.626 × 10 -34 joule·s
c = 2.998 Ă— 108 m/s
By multiplying to get a single expression, hc = 1.99 Ă— 10-25 joules-m
E=hc/λ
(6.626*10^-34 J*s) x (2.998Ă—10^8m/s)/ 1.5*10^-8 m
= 1.32*10^-17 J</span>
