ur answer is C) Bubbles formed in the magma when it was still in liquid form.
Answer:
The answer is below
Explanation:
Volt in physics is a term that is used to describe the unit of both electrical potential difference and electromotive force. In other words, it is a unit of measuring the voltage between two points. It is represented as "V".
The formula for Voltage is V=IR
Where V= Voltage, I = Current and R = Resistance.
<span>The competitive exclusion principle states that when
two organisms attempt to fill the same niche, one will exclude the other from
the ecosystem. Research partitioning is an adaptive evolution that when species
are have similar preys, they compete with each other and one species is deemed
to extinct in the process however if two species are of different preys, then
they can exist with one another. To exist with one another, organisms belonging
to a same species either compete for the resources or divide it amongst
themselves. This concept is important because it helps in diversified ecology,
where animals and plants of the same species co-exist and creates a beauty with
nature.</span>
Answer:
E = {(Charge Density/2e0)*(1 - [z/(sqrt(z^2 - R^2))]}
R is radius = Diameter/2 = 0.210m.
At z = 0.2m,
Put z = 0.2m, and charge density = 2.92 x 10^-2C/m2, and constant value e0 in the equation,
E can be calculated at distance 0.2m away from the centre of the disk.
Put z = 0.3m and all other values in the equation,
E can be calculated at distance 0.3m away from the centre of the disk
