Answer:
B
Explanation:
The capacitor is a component which has the ability to store energy in the form of an electrical charge making a potential difference on those two metal plates
A capacitor consists of two or more parallel conductive (metal) plates. They are electrically seperated by an insulating material (ex: air, mica,ceramic etc.) which is called as Dielectric Layer
Due to this insulating layer, DC current can not flow through the capacitor.But it allows a voltage to be present across the plates in the form of an electrical charge.
Answer:
21 Hz, 43 Hz and 22 Hz
Explanation:
The computation of the beat frequencies that are generated by this discordant combination is as follows:
As we know that
beat frequencies = |f_1 - f_2|
So
For the first one
= |349 Hz - 370 Hz|
= 21 Hz
For the second one
= |349 Hz - 392 Hz|
= 43 Hz
And, for the third one
= |370 Hz - 392 Hz|
= 22 Hz
The work done is 200 J
Explanation:
The work done by a force applied to move an object is given by:
where
F is the magnitude of the force
d is the displacement of the object
is the angle between the direction of the force and of the displacement
In this problem, assuming that the force applied by the workers is parallel to the direction of motion of the crate, we have:
F = 10.0 N
d = 20.0 m
Therefore, the work done is:

Then its acceleration must decrease, by the same factor as you increased the mass.
The PRODUCT of the (mass) times (acceleration) doesn't change.
It's equal to the force acting on the mass. (Newton #2: F = M·A.)
So, since the product has to remain constant, if you multiply the mass
by something, then the acceleration will divide by the same thing.
Answer:
After 3 hours.
Explanation:
This is a encounter problem.
We start by writing the position equation of both objects.
We assume that acceleration is equal to zero in both boats ⇒ They move with constant speed
We put the origin of coordinates in the harbour so after 6 hours the first boat travels
The first boat will be 42 mi far from the harbour.
The position equation for a motion with acceleration equal to zero is :
Where is initial position
v is the speed
t is time and is initial time
Then is time variation
For the first boat :
Because we set
For the second one :
In the encounter : x1(t) = x2(t) ⇒
So after 3 hours they have the same position relative to the harbour
We can check by replacing the value t = 3h in both position equations
For x1(t) :
For x2(t) :
