Electrons would likely pass through the plasma channel when the formation of a lightning takes place. Lightning is primarily caused by the formation of an ionised cloud in the atmosphere. This cloud was due to the attractions between molecules of rain drops wherein produce a negative charge.

. Find the buoyant force exerted on a ball with radius of 2 meters, when the ball is entirely immersed in the water.
almond37 [142]

Explanation:

Buoyancy force is equal to the weight of the displaced fluid:

B = ρVg

where ρ is the density of the fluid,

V is the volume of the displaced fluid,

and g is the acceleration due to gravity.

The fluid is water, so ρ = 1000 kg/m³.

The volume displaced is that of a sphere with radius 2 m:

V = 4/3 π r³

V = 4/3 π (2 m)³

V ≈ 33.5 m³

The buoyancy force is therefore:

B = (1000 kg/m³) (33.5 m³) (9.8 m/s²)

B ≈ 328,400 N

Round as needed.
