Answer: The correct answer is "magnetic field".
Explanation:
A magnetic field is produced around the current carrying wire.
If you bring compass needle around the current carrying wire then it shows the deflection which indicates that there is a magnetic field around the current carrying wire.
Magnetic fields are the area around the surrounding of magnet in which magnetic force can be experienced.
Therefore, a magnetic field is produced around a wire when an electrical current is in the wire.
Answer:
Explanation:
Assuming the picture is of a girl on a bicycle riding on level ground.
The rear wheel will see a force of 540 - 200 = 340
The general formula for power dissipation is:
Power = Current x Voltage
However, if you only know the voltage and the resistance, you can calculate the current using Ohm's Law, which is usually given as:
Voltage = Current x Resistance
However, you can rearrange this to give:
Current = Voltage/Resistance
You can then substitute this into the expression for power dissipation to yield an equation that gives an expression for power in terms of only voltage and resistance:
Power =
/ Resistance
It seems that you have missed the given options for the given statement above whether it is true or false. But anyway, the correct answer would be TRUE. It is true that one <span>of the most effective ways to evaluate data is to try to replicate it. Hope that this answer will help you. </span>
At 11,000 meters, the plane travels at the troposphere. In this particular layer of the atmosphere, the temperature gets colder, and the air pressure becomes less when the altitude increases.
Therefore, once the plane comes down to land, the decreasing altitude would cause the temperature to become warmer, and the air pressure to increase.
