Answer and Explanation :
The opposition of the flow of alternating current produced by a magnetic field is called inductive reactance it is denoted by
, The value of the inductive reactance depends on the value of inductance. The good thing about inductive reactance is that it is not responsible for the power loss as resistance is responsible for the power loss
The answer is c. The particles of b are more closely packed
Answer:
Water in an artificial lake held behind a dam
Explanation:
Potential energy is energy that can be converted to kinetic energy, for example, an object at a certain height has potential energy because we can drop the object to have kinetic energy.
Therefore, the best example of potential energy is water in an artificial lake held behind a dam because without the dam, the water will start to move and it becomes the energy into kinetic energy.
I’m not sure look it up or ask for a tutor on here it’s free
Answer:
Here is the answer. Hope this helps you!
Explanation:
Average velocity is the sum of initial and final velocity divided by 2. I t is the same as total Displacement divided by total time. Average velocity is calculated when the body is in non-uniform motion (also when total displacement and time is not given). The formula is as follows:
u + v/2 =
Average velocity = Average speed
during motion in a straight line. therefore, the above mentioned formula can be used for calculating average speed as well, when the direction is one and only the same, that is, during motion in a straight line. The S.I unit remains the same-
m/s.
Since velocity is vector, average VELOCITY is also vector. However, Average SPEED is scalar as speed is scalar. both can be equal only when the distance = displacement and when they are following the same direction of motion.
