Well first of all, here's something you're going to need:
Power = (energy) / (time) 1 watt = (1 joule) per second
Energy = (power) x (time) 1 joule = (1 watt) x (1 second)
At this point, your progress grinds to a stop, because, technically, the
current alone doesn't tell you the power. In other words, 'Amperes'
alone doesn't give you the 'watts'.
Power (watts) = (amperes) times (volts) .
So you need to either go ask somebody or else <em>assume</em> the <u>voltage</u>
of the outlet that the microwave oven is plugged into. Without it,
the question can't be answered.
I'm going to assume that you live and go to school somewhere in the USA,
Canada, or Mexico. If that's true, then the outlets in your house supply
electrical energy at 120 volts, and everything you plug into them is designed
to run on 120 volts. Now you have enough information to solve the problem.
Power = (15 amperes) x (120 volts) = 1,800 watts
Energy = (power) x (time) =
(1,800 watts) x (20 minutes) x (60 seconds/minute) =
2,160,000 watt-seconds = <em>2,160,000 joules</em>
Answer: Electric current
Explanation :
The direction of the magnetic field produced by an electric current will change when the direction of the electric current changes.
For example :
If a current is flowing in a straight length of wire, the magnetic field is described by a concentric circle (using right-hand rule).
Let the field lines are in the clockwise direction and when the direction of current is reversed then the direction of the magnetic field is in anticlockwise direction.
The currents in the wires are in opposite directions.
- Two long parallel wires separated by a distance 'r' having current and have force per unit length which is given by .....(1) where is permittivity of free space whose value is .
If the current flowing through the wire are in same direction then they the wire attract each other and if the current flowing through the wire are opposite in direction then they the wire repel each other .
As it is given that two wires repel each other which means that current in the wires are in opposite direction .
Hence current flowing through wires are opposite in direction.

The Kyoto Protocol, which limits emissions of greenhouse gases for developed nations, is an example of international Law
Explanation:
The Kyoto Protocol is named after a Japanese city in which it was executed in the year 1997 on 1st December.
The basic aim of the Kyoto Protocol is to reduce/Limit the emission of greenhouse gases which contributed to global warming
The Protocol was linked to the United Nations Framework Convention on Climate Change (UNFCCC)
The important factor that led to the failure of Kyoto's Protocol are deficiencies in the structure of the agreement, such as the exemption of developing countries from reductions requirements, or the lack of an effective emissions trading scheme
