Answer:
The direction of magnetic field produced by a current carrying wire is given by the right hand thumb rule. If the thumb points in the direction of current the fingers curl along the direction of magnetic field.
further, The red end of the compass needle points in the direction of external magnetic field. As the red end of the needle is pointing away from us, the external magnetic field at its location should also be directed away from us. Using the right hand thumb rule, we can see that this is only possible if the current in the wire is flowing upwards.
Explanation:
Energy is in Joules ( J )
specific heat capacity is in ( Joules per Kilogram per degree Celsius) ( J/kg C )
Answer: 4. Infrared radiation
Explanation: Both carbon dioxide and methane are excellent absorbers of heat. The heat energy causes the molecule of carbon dioxide and methane to vibrate. As a result of this, the molecules gives up the extra energy by emitting infrared photon.
Therefore, the Evidence that supports the idea that increases in carbon dioxide and methane in Earth's atmosphere are major contributors to global warming is primarily based on the fact that carbon dioxide and methane are excellent absorbers of infrared radiation
Condensation<span> is the change of </span>water<span> from its gaseous form (</span>water vapor) into liquid water<span>. </span>Condensation<span> occurs in the atmosphere when warm air rises, cools and looses its capacity to hold </span>water vapor<span>. As a result, excess </span>water vapor <span>condenses to form cloud droplets.</span>
Greenhouse gases, eg. carbon dioxide and methane.
