First one I believe but im not completely sure
P=mv
pi =pf
(68x2.79)+(131x0) = 199v
v= 0.95 m/s
∆x (displacement) = v - u
where, v is the final position and u is the initial position.
Given, the final position of the object is 0 m and the initial position is 5 m.
∆x (displacement) = v - u
= 0 m - 5 m
= -5 m
Therefore, <u>C: -5m</u> is the correct answer.
Yes, an object<span> that was set in motion in the past by some force, but that is no longer being acted on by a net force, is </span>moving<span> but with </span>zero acceleration<span>, i.e. it is </span>moving<span> at constant velocity.</span>
Answer:
Volume, 
Explanation:
Given that,
The diameter of a human cell is 11 μm
It is enclosed by a membrane that is 4,4 nm thick.
We need to find the volume of the cell. The cell is spherical in shape. The volume of a sphere is given by the formula as follows :

r is the radius of the sphere, r = 5.5 μm
So,

So, the volume of the cell is
.
