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.
Answer:
C)evaporating of water
Explanation:that is because waters physical property is lost after evaporating
Answer:
3. Work
Explanation:
Number 1 isn't correct because you are not using efficiency to hold books and walk across the room.
Number 2 could be correct but isn't in this situation because you use power only to hold the books but not to walk across the room.
Number 4 is not correct because you need to do work to do something.
Answer:
2.5 mi/s^2
Explanation:
please see paper for work!
A) <span>Ivan does work when he lifts the basket
B) Work = Force * displacement
W = 20 * 2
W = 40 Joules
So, The Amount of work he does is 40 Joules
Hope this helps!</span>
