Explanation:
Answer:
Explanation:
Given
two holes are made with different sizes
Hole 1 is large in size and hole 2 is small
If the volume flow rate of water is same for both the hole then small hole must be below the large hole because for same flow rate, velocity of water is large while cross-sectional area is small so it compensate to give same flow for both the holes.
Now for radius apply Bernoulli's theorem at hole 1 and 2


if hole 1 is h distance below water surface then 
and 
Also 

and 

thus 


Answer:
3.6*10¹⁰N/C
Explanation:
The formula for Electric field strength is expressed as:
E = kQ/r²
k is the coulombs constant = 9*10^9Nm²/C²
Q is the charge = 1.00×10°C
r is the distance = 0.50m
Substitute the parameters into the formula as shown:
E = kQ/r²
E = 9*10^9(1)/0.5²
E = 9*10^9/0.25
E = 36*10^9
<em>E = 3.6*10¹⁰N/C</em>
<em>Hence the electric field strength is 3.6*10¹⁰N/C </em>
I took the test, its constructive interference
Edit: this is kind of a trick question. took the test again it was the same question yet this time the answer was destructive. Good luck with that
