<span>In my opinion, I myself believe that there are only two supernovae. The first is the white dwarf. It makes sense because if something is too big for its size, it will "explode". Just like a basketball with too much air. Massive star supernovae is like something has reached it's full potential and cannot get any bigger or better.</span>
I don’t understand the question
Hey I thought we were going out tonight but we are going out to dinner with the girls and we will go back together lol I have a nice weekend and we will go aback lol I love it so I can go get my food and I can eat tonight and go back home.
Answer:
I = 6.4*10¹⁷ W/m²
Explanation:
As the intensity of a light source is defined as the light power divided by the illuminated area, we need first to find the power emitted by the laser during the pulse.
As power is defined as energy per unit time, we can find the power P as follows:
⇒ P = 5*10⁷ W
As the laser is a narrow-beam source, we can find the intensity dividing the power we have just found above, by the area of the circle over which the light is focused:
⇒ I = 6.4*10¹⁷ W/m²
