I believe the answer is a: cells.
When plates pull apart underwater, the hot magma instantly rises and spreads itself to form a new ocean floor.Under a continent, the crust splits open to allow magma out. The magma might make its way slowly to the surface, creating warm areas and hot springs or geysers as surface water meets it.<span>Or the magma might explode, bringing into existence a new volcano where there was only cool earth before.</span>
Answer: A)
Explanation: when an electron is placed in a magnetic field, it experiences a force.
This force is given below as
F=qvB*sinθ
F = force experienced by charge.
q = magnitude of electronic charge
v = speed of electron
B= strength of magnetic field
θ = angle between magnetic field and velocity.
What defines the force exerted on the charge is the angle between the field and it velocity.
If magnetic field is parallel to velocity, then it means that θ=0° which means sin 0 = 0, which means
F = qvB * 0 = 0.
The charge being at rest has nothing to do with the angle between magnetic field strength and velocity.
The arrows around the positive point charge illustrates the direction of the electric force/field.
<h3>What is Electric field?</h3>
This is described as an area in which force is exerted om other charged particles or objects.
Arrows could be around the positive or negative point charge and helps to depict the direction of the electric force.

Yes I believe in god.I believe in him because there is huge gaps in science that can not be solved. I also believe in him because I was also taught about him when I was little by family & my mom so I grew up learning about him which made my beliefs stronger of course.
