Its C because if it is a low frequency it will not change much so it will be a longer wavelength and the higher the frequency the shorter the wavelength
Answer:
water
Explanation:
water is not an element, it is a molecule
Answer:
Explanation:
Let the potential difference between the plate is V . Then in the first case
Electric field E between plate
E₁ = V / d
where d is separation between plate
When the plate separation becomes d / 2
Electric field E between plate
E₂ = V / d /2
= 2 V / d =2E₁
Or twice the earlier field
Solution :
We know, resistance is given by :


Now, we know mass of wire is given by :

Hence, this is the required solution.
Answer:
um d. but I am guessing this ans
