Answer:
1371.4watt
Explanation:
from power=energy/time
BUT energy=force times distance
To solve this problem it is necessary to apply the concepts related to the principle of superposition and the equations of destructive and constructive interference.
Constructive interference can be defined as

Where
m= Any integer which represent the number of repetition of spectrum
= Wavelength
d = Distance between the slits.
= Angle between the difraccion paterns and the source of light
Re-arrange to find the distance between the slits we have,



Therefore the number of lines per millimeter would be given as



Therefore the number of the lines from the grating to the center of the diffraction pattern are 380lines per mm
Answer:
o
Explanation:
the increase energy stored in thw system is proportional to the decrease in kinetic energy
It must gain an electron because if the proton number was to change it would no longer be the same element.
