It gives off no radiation. This means that it doesn’t interact with the light.
Answer:
false you balance by having the same number of atom on the reactants side and the products side
ex: 1N2 + 3H2 -----> 2NH3
reactants on the left and the product is on the right

Answer:
240 nm
Explanation:
In the interference in thin films , light reflected from upper surface and light reflected from the lower surface of oil are made to interfere each other to form fringes due to path difference of 2μt .
a ) An additional phase shift of 180 ° occurs on the upper surface because light is going from optically rarer medium to denser medium .
b ) There is no such change on reflection from lower surface as light is going from denser to rarer medium ( air ).
c ) For destructive interference the path difference which is equal to 2 μ t should be equal to n λ where n is any number
So for given condition
2 μ t = n λ
For minimum thickness
2 μ t = λ ( n =1 )
t = λ / 2μ
= 600 x 10⁻⁹ /( 2 x 1.25 )
= 240 nm
Answer:
-10.8m/s^2
Explanation:
a=change in velocity/change in time
-27 m/s/2.5=10.8m/s^2
or if its not negative
27m/s/2.5=10.8m/s^2
