Answer:
The volume of the submerged part of her body is 
Explanation:
Let's define the buoyant force acting on a submerged object.
In a submerged object acts a buoyant force which can be calculated as :
ρ.V.g
Where ''B'' is the buoyant force
Where ''ρ'' is the density of the fluid
Where ''V'' is the submerged volume of the object
Where ''g'' is the acceleration due to gravity
Because the girl is floating we can state that the weight of the girl is equal to the buoyant force.
We can write :
(I)
Where ''W'' is weight
⇒ If we consider ρ = 
(water density) and 
and replacing this values in the equation (I) ⇒
ρ.V.g = 610N
(II)
The force unit ''N'' (Newton) is defined as
Using this in the equation (II) :
We find that the volume of the submerged part of her body is
Unlike a longitudinal wave, a transverse wave moves about, perpendicular to the direction of propagation. The particles in a transverse wave do not travel along the direction of propagation, but only oscillate up and down on its equilibrium position. With this, the displacement can be determined by measuring (in the case of electronic waves, using an oscilloscope or spectrum analyzer) and setting the desired units to measure the wave in.
Answer:
AC motor........A
Explanation:
Plato, an AC motor is much simpler than a DC motor. As alternating current passes through the coil, it becomes magnetized. Since the current is alternating, the north and south ends keep switching.
The required equation for the sine function can be written as; V = 120sin120πt
<h3>What is a sine function?</h3>
A sine function is a regular repeating function. We know that the voltage is represented using a sine function of the general form V= V-o sin2πft
Hence;
f = 60 cycles per second
V-o = 120 volts
So from the values that we have stated above;
V = 120sin120πt

Hello,
I believe that the answer is <span>A) Geothermal power plants use the renewable resource of heat from within the Earth to generate electricity.
I truely hope this helps.</span>
