Answer:
Not including a sedimentary cover of variable thickness and composition, the oceanic crust consists of three layers: (1) a relatively thin uppermost volcanic layer of basaltic lavas known as mid-ocean ridge basalts (MORB) erupted on the seafloor; (2) a thicker layer of more coarsely crystalline, intrusive basaltic
C) The magnetic field is the strongest inside the current-carrying coil
This is because the magnetic field lines are packed the closest here.
Answer:
The wavelength of the wave is 2.34 nm.
Explanation:
It is required to find the wavelength of a
wave. A wave moves with a speed of light. Speed of a wave is given in terms of wavelength and frequency. So,
![v=f\lambda](https://tex.z-dn.net/?f=v%3Df%5Clambda)
![\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{1.28\times 10^{17}}\\\\\lambda=2.34\times 10^{-9}\ m\\\\\text{or}\\\\\lambda=2.34\ nm](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7Bc%7D%7Bf%7D%5C%5C%5C%5C%5Clambda%3D%5Cdfrac%7B3%5Ctimes%2010%5E8%7D%7B1.28%5Ctimes%2010%5E%7B17%7D%7D%5C%5C%5C%5C%5Clambda%3D2.34%5Ctimes%2010%5E%7B-9%7D%5C%20m%5C%5C%5C%5C%5Ctext%7Bor%7D%5C%5C%5C%5C%5Clambda%3D2.34%5C%20nm)
So, the wavelength of the wave is 2.34 nm.
The answer to the first question is D. Sun.
For the next one the answer is D. The water droplets fall to earth as rain.
Next one is the Sun I think. Hope these answers help (sorry if I missed one, the numbers were a little wonky)
Answer:
(a) W = 1329.5 J = 1.33 KJ
(b) ΔU = 24.27 KJ
Explanation:
(a)
Work done by the gas can be found by the following formula:
![W = P\Delta V](https://tex.z-dn.net/?f=W%20%3D%20P%5CDelta%20V)
where,
W = Work = ?
P = constant pressure = (0.991 atm)(
) = 100413 Pa
ΔV = Change in Volume = 18.7 L - 5.46 L = (13.24 L)(
) = 0.01324 m³
Therefore,
W = (100413 Pa)(0.01324 m³)
<u>W = 1329.5 J = 1.33 KJ</u>
<u></u>
(b)
Using the first law of thermodynamics:
ΔU = ΔQ - W (negative W for the work done by the system)
where,
ΔU = change in internal energy of the gas = ?
ΔQ = heat added to the system = 25.6 KJ
Therefore,
ΔU = 25.6 KJ - 1.33 KJ
<u>ΔU = 24.27 KJ</u>
