Answer:
Les facteurs abiotiques font référence aux éléments physiques et chimiques non vivants de l'écosystème. Les ressources abiotiques proviennent généralement de la lithosphère, de l'atmosphère et de l'hydrosphère.

Answer:
8 x 10^-8 C on both the spheres.
Explanation:
Number of electrons added to A = 1 x 10^12
As the sphere A and B are identical to each other so the charge is shared equally.
Charge of one electron = 1.6 x 10^-19 C
Charge on A after wards
= number of electrons after wards x charge of one electron
qA = 0.5 x 10^12 x 1.6 x 10^-19 = 8 x 10^-8 C
Similarly, the charge on sphere B afterwards
= number of electrons after wards x charge of one electron
qB = 0.5 x 10^12 x 1.6 x 10^-19 = 8 x 10^-8 C
A megawatt is larger than a kilowatt. The scientific notation for kilo is 10 to the 3, meaning 1000. A mega is 10 to the 6, meaning one million. That means a kilo watt is a thousand watts, and mega is a million watts
Answer:
Explanation:
a )
Moment of inertial of four masses about axis that coincides with one side :
Out of four masses . location of two masses will lie on the axis so their moment of inertia will be zero .
Moment of inertia of the two remaining masses
= m L² + m L²
= 2 mL²
b )
Axis that bisects two opposite sides
Each of the four masses will lie at a distance of L / 2 from this axis so moment of inertia of the four masses
= 4 x m x ( L/2 )²
= 4 x mL² / 4
= m L² .
A lot of it is all experimental as long as you are taking caution of safety while doing it. I personally would use copper wiring mainly for the fact that it is a nice conductor. For the wrap around the wiring i usually would use black or red electrical tape just because it has very nice insulator properties and is safe to use.
