Wildfires benefit grasslands, northern forests, and deciduous forests. Grasslands are benefited by improved soil quality and control of tree cover. Invertebrate species diversity is maintained through wildfire as well. Northern forests, like grasslands, experience increased production and nutritional quality of food as a result of wildfires. Deciduous forests experience an increase in the nutritional quality of food as well, but the effects are more temporary. The amount of shrubs in deciduous forests is reduced as a result of wildfires, allowing more herbaceous plants such as mosses and lichens to grow.
Elastic potential energy.
When you stretch a rubber band it has the "potential" to do work, to fly in a given direction. In doing so it changes it's elastic potential energy to kinetic energy.
Answer:
The magnetic field will be , '2d' being the distance the wires.
Explanation:
From Biot-Savart's law, the magnetic field () at a distance '' due to a current carrying conductor carrying current '' is given by
where '' is an elemental length along the direction of the current flow through the conductor.
Using this law, the magnetic field due to straight current carrying conductor having current '', at a distance '' is given by
According to the figure if '' be the current carried by the top wire, '' be the current carried by the bottom wire and '' be the distance between them, then the direction of the magnetic field at 'P', which is midway between them, will be perpendicular towards the plane of the screen, shown by the symbol and that due to the bottom wire at 'P' will be perpendicular away from the plane of the screen, shown by symbol.
Given and
Therefore, the magnetic field () at 'P' due to the top wire
and the magnetic field () at 'P' due to the bottom wire
Therefore taking the value of the net magnetic field () at the midway between the wires will be
