Answer:
Explanation:
Arrangement of all known elements to men based on state of matter reactivity and valence shell structure
Answer:
<em>BCEG,ADF</em>
Explanation:
Between 2 waves, if path difference is mλ, m is an integer and they interfere constructively.
Between 2 waves, if path difference is (m+1/2)λ, m is an integer and they interfere destructively.
<em>BCEG,ADF</em>
Condition for diffraction

Where
a = Distance between slits
m = Order of the fringes
= Wavelength
= At the angle between the ray of light and the projected distance perpendicular between the two objects
For small angles

Where

Where L is the distance between the slits and Y the length of the light.
Replacing we have


The distance between slits d can be expressed also as
Where N is the number of the fringes, then

Similarly when there is added a new Fringe we have the change of the distance would be :

Linear distance between fringes is


Therefore the answer is

All isotopes contain different number of neutrons then the original element
During the period of constant acceleration, the car's average speed is (1/2) (16 + 32) = 24 m/s.
At that average speed, it covers 240 meters in 10 seconds.
