Answer:
The water is flowing at the rate of 28.04 m/s.
Explanation:
Given;
Height of sea water, z₁ = 10.5 m
gauge pressure, = 2.95 atm
Atmospheric pressure, = 101325 Pa
To determine the speed of the water, apply Bernoulli's equation;
where;
P₁ =
P₂ =
v₁ = 0
z₂ = 0
Substitute in these values and the Bernoulli's equation will reduce to;
where;
is the density of seawater = 1030 kg/m³
Therefore, the water is flowing at the rate of 28.04 m/s.
Answer:
v = 2.85 m/s
Explanation:
By the law of similarity of the triangle we can say
here we know that
height of man = 2 m
let the distance of man from spotlight = x
distance of wall from spotlight = 12 m
height of image is let say "y"
so we will have
now we have
here we know
x = 4 m
now we have
The most untrue statement is that a good scientist is influenced by their likes and dislikes. What we like has no bearing on the nature of the cosmos.
