Hence,
<span>∆H = ∆U + W </span>
<span>=> </span>
<span>W = ∆H - ∆U </span>
<span>= -5074 kJ - (-5084.) kJ </span>
<span>= 10 kJ</span>
Answer:
D. 12 cm
Explanation:
A node is a point on a standing wave that does not vibrate.
The nodes of a standing wave are shown in the following sketch.
The red dots are the nodes of the standing wave.
It is observed that the distance between two adjacent nodes is half the wavelength of the wave.
Therefore, if the wavelength of the wave is 24 cm, then the distance from one node to the net must be 24 / 2 = 12 cm.
Hence, choice D is the correct answer.
The Sun has<span> an "absolute magnitude" of </span>4.83 and an "apparent" magnitude of -26.8. (Which is the difference between the numbers). <span>Scientists use what is know as "</span>Absolute" Magnitude<span> to help them understand and compute how bright a star really is. The "</span>absolute" magnitude<span> of an object, such as a star, equals how bright that object would look if it were 10 parsecs, or 32.6 light years away from the Earth.</span>
<span>Because the droplets are conductors, a droplet's positive and negative charges will separate while the droplet is in the region between the deflection plates. You are given a situation that if a neutral droplet passes between the plates. The droplet's dipole moment will point at the center of the droplet.</span>
