Answer:
b. False
Explanation:
The Bernoulli's equation is given by;
Divide through by the density of the fluid and acceleration due to gravity (ρg), to obtain energy per unit weight of the fluid known as head;
where;
is pressure head
h is datum head (mechanical energy due to height of the fluid)
is velocity head (mechanical energy due to velocity of the fluid)
Thus, the mechanical energy of a fluid per unit weight of the fluid, measured relative to the bottom of the channel is datum head.
The correct option is "b. False"
Answer:
The magnitude of the torque about the origin is 108 N-m.
Explanation:
Given that,
Mass of the stone, m = 2 kg
Length of the string, l = 0.5 m
Angular velocity of the stone,
The circle is parallel to the xy plane and is centered on the z axis, 0.75 m from the origin, r = 0.75 m
Firstly it is required to find the centripetal force acting on the stone. It is given by :
F = 144 N
Now the magnitude of the torque about the origin is given by :
So, the magnitude of the torque about the origin is 108 N-m. Hence, this is the required solution.

Give it to me now peasant
The electric potential energy of the charge will be =3.5*10^8 J
<h3 /><h3>What is Electric potential energy?</h3>
Electric potential energy is the energy that is needed to move a charge against an electric field.
F=Force experienced by the charge = 3.6*10^-4 N
q1 = magnitude of charge producing the electric field
q2 = magnitude of charge experiencing the electric force
r1 = distance between the two charges
Electric force experienced by the charge is given using coulomb's law as
Electric potential energy of the charge can be given as
Thus Electric potential energy of the charge can be given as
