The heat energy released from a piece of wire or any other section of a circuit is:
Energy = (voltage between its ends) x (current through it) x (time it's been going)
Answer:
The maximum value of the magnetic field in the wave is .
Explanation:
Given that,
Average value of pointing vector = 0.724 W/m²
We need to calculate the magnetic field
Using formula of pointing vector
The average value of pointing vector
....(I)
We know that,
Put the value of in equation (II)
Put the value into the formula
Hence, The maximum value of the magnetic field in the wave is .
Answer:
I haven’t done this in a while but i think b
Explanation:
lf a heavy point mass is suspended by a weightless, inextensible and perfectly flexible string from a rigid support, then this arrangement is called simple pendulum.
In practice, however, these requirements cannot be fulfilled. So we use a practical pendulum.
A practical pendulum consists of a small metallic solid sphere suspended by a fine silk thread from a rigid support. This is the practical simple pendulum which is nearest to the ideal simple pendulum.
Note :
The metallic sphere is called the bob.
When the bob is displaced slightly to one side from its mean position and released, it oscillates about its mean position in a vertical plane.
Answer:
To pinpoint specific locations on Earth
Explanation:
The satellite has a full specific view of a specific area just like other satellites do. Satellites communicate together which also communicates with your GPS to give you an accurate location where you are or where you want to be. That is how satellites are used in GPS.
Hope this helps you out :)
