Answer:
60 N
Explanation:
because when we double the 30N, we will get 60N as a force
The wavelength emitted is indirectly proportional to the difference in the change in the energy level. For the wavelength 278 nm the change in energy level is significantly high. Further change in energy level is indicated by 454nm light but the difference in energy level for this wavelength to be emitted is not greater than the previous one. There is a possibility that these subsystems have now very low energy which should result in wavelengths ranging from 700 to 900 nm. There is another possibility that there is some metastable subsystems in the system which may cause LASER emission.
Answer: The answer is A
Explanation: The bumper is the first part of an automobile to be impacted when in a head-on accident
It is potential energy because the band is not in movement, th band has the potential to move.
