Power in most circuits could be analysed and broken down into two categories
-Power dissipated by resistive components
-Power delivered by the electrical sources.
If you are working with Alternate current (AC) sources, the analysis of the power consumed in the circuit will deal with complex numbers and the introduction of new terms such as active, reactive and apparent power.
All this depending on the frequency and the components used in the circuit.
Answer:
Option b
Explanation:
An object is said to fall freely when there is no force acting on the object other than the gravitational force. Thus the acceleration of the object is solely due to gravity and no other acceleration acts on the body.
Also the initial velocity of the body in free fall is zero and hence less than the final velocity.
As the body falls down closer to earth, it experiences more gravitational pull and the velocity increases as it falls down and the moment it touches the ground the period of free fall ends at that instant.
Thus the final velocity of an object in free fall is not zero because the final velocity is the velocity before coming in contact with the ground.
Mostly gravity voloume and sometimes what it is made of
Answer:
D). Field lines circle the Earth from east to west.
Explanation:
A microscopic force or gigantic magnetic field surrounds the Earth which functions as a force field that guards the planet against the radiations released from space. This magnetic field is characterized by the alignment of the North and South poles with the axis of rotation. Thus, the magnetic field lines of the Earth surround or circle of the Earth from East to West. Therefore, <u>option D</u> is the correct answer.
