Answer:
Option A and B
Explanation:
In the parallel connection, the capacitors that are connected in parallel have the same potential difference across each capacitor as the battery. Therefore, statement A is correct.
Charge (Q), capacitance (C) and voltage across capacitor (V) is related with each other as follows:
Q = C ×V
As capacitance is not same for all the capacitors, therefore each capacitor carries different charge. Therefore, statement C is incorrect.
As potential difference across each capacitor is same, therefore, capacitor with the largest capacitance carry the most charge. Therefore, statement B is correct.
Therefore, statements A and B are correct.
Answer:
From Faraday's law of Induction: A changing magnetic field induces emf in the coil.
Explanation:
<u>Faraday's law</u> states that when a coil is run through a changing magnetic field or a magnet is passed back and forth through a coil, a<u>n emf is induced which produces electric current in the coil. </u>
Changing magnetic flux induces electromotive force.
When the magnet is passed back and forth, it causes a changing magnetic flux around the coil. This induces emf and the current flows which lights up the bulb connected to it.
The height isn’t a factor.
The gravitational force is the same no matter the height...
So W=mg
20 x 9.81 = 196.2 N
Answer:
Using the parallel axis theorem
Explanation:
We note the angular speed and also the systems energy. Using these information we calculate the moment of inertia of irregular shaped body.
Io = 2E/w²
When we have moment of inertia of irregular shaped body, we can then use parallel axis theorem to solve for the moment of inertia of the body about the given axis.
I = Io + md²
The correct answer is A, Allow the cell to he motile
