A wave where the oscillation is parallel to the motion is a longitudinal wave
The energy stored in the membrane is
Explanation:
The capacitance of a parallel-plate capacitor is given by
where
k is the dielectric constant of the material
is the vacuum permittivity
A is the area of the plates
d is the separation between the plates
For the membrane in this problem, we have
k = 4.6
Substituting, we find its capacitance:
Now we can find the energy stored: for a capacitor, it is given by
where
is the capacitance
is the potential difference
Substituting,

Answer:
Explanation:
Given:
velocity of the sound,
time lag in echo form one wall of the valley,
time lag in echo form the other wall of the valley,
<u>distance travelled by the sound in the first case:</u>
Since this is the distance covered by the sound while going form the source to the walls and then coming back from the wall to the source so the distance of the wall form the source will be half of the distance obtained above.
<u>distance travelled by the sound in the second case:</u>
Since this is the distance covered by the sound while going form the source to the walls and then coming back from the wall to the source so the distance of the wall form the source will be half of the distance obtained above.
<u>Now the width of valley:</u>
The magnitude of force needed to be applied on the machine is of 15,000 N.
How mechanical advantage is related to output force?
The ratio of force output to the applied force gives the value of the mechanical advantage. In other words, the mechanical advantage has a direct relation with the force output.
Given data:
The value of the mechanical advantage is, MA = 5.
The magnitude of applied force is, F = 3000 N.
Since the output force is the force exerted on the machine. Then the relation is given as,
MA = F'/F
here,
F' is the magnitude of the force exerted on the machine.
Solving as,
5 = F'/3000
F' = 5 × 3000
F' = 15,000 N
Thus, we can conclude that the magnitude of force needed to be applied on the machine is of 15,000 N.
