diabetes is not as risky as the Corona virus
Answer:
x = 625 m
Explanation:
To solve this exercise we use the kinematics relations
v² = v₀² - 2 a x
indicate that the train stops therefore its final speed is zero (v = 0)
0 = v₀² - 2a x
x =
let's slow down to the SI system
v₀ = 90 km / h (1000 m / 1km) (1h / 3600 s) = 25 m / s
let's calculate
x =
x = 625 m
Answer:
"jumps" from one energy level down to another lower energy level.
Explanation:
The light observed in such a spectrum is emitted when an electron in an atom "jumps" from one energy level down to another lower energy level. When an electron does this , it emits energy equal to difference in the energy level of two shell in which the electron jumps.
And this emitted light is separated out into individual colors using a prism or diffraction grating and a few lines of colored light are seen.
I’m sure it’s called a circuit:)
