Neither do.beacuse diffusion occurs due the random movement a substance's particals move from a higher concentration to a lower concentration down the concentration gradient.On the other hand osmosis is the movement of water molecules from a high water potential to a low water potential through a partially permeable membrane.thus no energy is required for them to do so.Active transport is a process that requires energy.
You need to do spring constant x extension
-981N would be the reaction force of a person be that stands completely still with a mass of 100 kg.
An opposing force to an action force is referred to as a reaction force. The response force that results from surface engagement and adhesion while sliding is known as friction. Usually, the activities of applied forces result in reaction forces and reaction moments.
As,
F = ma
where, F = force
m = mass of object
a = acceleration due to gravity
Plugging in the values we get,
F = 100kg × 9.81m/s
F = 981 N
Since, reaction force acts opposite to action force so the correct answer is -981N.

Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.
There are 2 elements:
Beryllium ( Be + 2 ), metal
Bromine ( Br - 1 ), non - metal
They form the ionic bond:
Be + Br2 → Be Br2
Naming the ionic compound:
on the 1st place is metal. On the 2nd place is non-metal. If compound is binary, use the element name and change ending to - ide .
Answer:
Beryllium Bromide.
