Answer:
Interference
Explanation:
Interference is the phenomenon in which two waves superimpose to form a wave with smaller, larger or same amplitude.
There are two types of interference namely, constructive interference and destructive interference.
Constructive interference occurs when the waves are in phase and destructive interference occurs when the waves are out of phase.
In a double slit experiment, the two slits acts as sources of light and thus the waves combine to produce interference patterns. When the waves are in phase, that is the angle between them is 0°, they form a constructive interference pattern which gives rise to a light band. When the waves are out of phase, that is the angle between them is 180°, they form a destructive interference pattern which gives rise to a dark band.
Note also that diffraction patterns are also observed for wide slits but can be neglected for smaller slits.
Answer:
c). 
Explanation:
As we know that weight of the automobile is given here
so weight = mass times gravity
now from Newton's law
Answer:
Cost = 40 fills
Explanation:
First, we will calculate the total power consumed by all appliances:
Now, we will calculate the energy required:
Now, for the cost we use the following formula:
<u>Cost = 40 fills</u>
