Answer:
the velocity of the water flow is 7.92 m/s
Explanation:
The computation of the velocity of the water flow is as follows
Here we use the Bernouli equation
As we know that
= 7.92 m/s
Hence, the velocity of the water flow is 7.92 m/s
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Answer:
ρ = 1.70 Ωm
Explanation:
given data
diameter = 1.8 mm
distance = 4.8 cm
volt = 9 V
potential difference = 280
solution
we know that Resistance that is express as
Resistance = ..............1
V = I × R
and
V = I × ..........2
put here value we get
9 = 280 × ×
ρ = 1.70 Ωm
