When applying Gauss' law for a capacitor containing a dielectric, which of the following statements is false? (Latter part of se
1 answer:
Answer:a
Explanation:
Introducing a dielectric inside a capacitor reduces the Electric field . Charge develops on dielectric such that it is opposite to the corresponding face . For example Positive charge of capacitor induces negative charge on dielectric which will create an Electric Field in opposite direction.
So Electric Field decreased by a factor of where

Answer:
Action force: Would be the force of your feet against the Earth given by the weight defined as:
Where g is a constat who represent the gravity in Earth
Reaction force: Would be the force of the Earth pushing against your feet. And on this case is represented by the normal force defined as:
Where represent the friction coefficient between the ground and the object.
And the friction force.
If we don't have any other forces involved in the y axis we can conclude that:
And as we can see we have that Action force = Reaction force
So then the third Law of Newton is satisfied.
Explanation:
For this case we have this:
Action force: Would be the force of your feet against the Earth given by the weight defined as:
Where g is a constat who represent the gravity in Earth
Reaction force: Would be the force of the Earth pushing against your feet. And on this case is represented by the normal force defined as:
Where represent the friction coefficient between the ground and the object.
And the friction force.
If we don't have any other forces involved in the y axis we can conclude that:
And as we can see we have that Action force = Reaction force
So then the third Law of Newton is satisfied.
Answer:
304.86 metres
Explanation:
The x and y cordinates are and
respectively
The horizontal distance travelled,
Making t the subject,
Since , we substitute t with the above and obtain
Making d the subject we obtain
d=304.8584
d=304.86m
