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:
It’s called a conservative field.
Explanation:
I think it’s going to be the conservative field because in the question it talks about how it is able to become possible to define potential at a point in an electric field because electric field.
I believe it’s 1 aka A part of it is reflected as Ray 2
Answer:
<u>Work done by the force acting on a body is defined as the product of force and displacement of the body in the direction of the force.</u><u> </u> It is a scalar quantity. Force acting on the body must produce a displacement for the work is to be done by the force. Thus, for the work to be done, the following conditions must be fulfilled:
A force must be applied and the applied force must produce a displacement in any direction except perpendicular to the direction of the force.
Mathematically,
( in the direction of force)
i.e W= F•D
The SI unit of force is Newton (N) and that of displacement of a metre (M). So the unit of work is Newton metre(Nm) which is joule (J).
Thus, one joule work is said to be done when one Newton force displaces a body through one metre in its own direction.
Hope this helps...
Good luck on your assignment..
