Answer:
See below ~
Explanation:
Part (a) :
We can say a body is in uniform acceleration if the acceleration of the object remains constant with respect to time throughout its motion.
Part (b) :
We can say a body is non-uniform acceleration if the acceleration of the body varies with respect to time throughout its motion.

Complete Question:
Part B - Permeability of the lipid bilayer Some solutes are able to pass directly through the lipid bilayer of a plasma membrane, whereas other solutes require a transport protein or other mechanism to cross between the inside and the outside of a cell. The fact that the plasma membrane is permeable to some solutes but not others is what is referred to as selective permeability. Which of the following molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism?
a) proteins
b) water
c) ions
d) sucrose
e) lipids
f) carbon dioxide
g) oxygen
Answer:
b) water
e) lipids
f) carbon dioxide
g) oxygen
Explanation:
Diffusion is the means by which molecules like water, lipids, carbon dioxide and oxygen easily move across the lipid bilayer of a membrane directly without the use of a transport protein or any another mechanism.
Diffusion is the way or means through which molecules( such as gases or liquids) move across a membrane from and region of higher concentration to a region of lower concentration.
Before a molecule can pass through the semi permeable membrane without the use of any mechanism or transport protein, it has to be:
a) a small molecule
b) an uncharged molecule
c) an hydrophobic molecule
First of all, that's not an equation. An equation needs an 'equals' sign ( = ),
so you need something like
Amount present = a e^-0.0025t .
'a' = amount present when t = 0 .
The half-life is the time it takes for the original amount to decay to half of it.
That's just 't' when e^-0.0025t = 1/2
Take the natural log of each side: -0.0025t = ln(0.5)
Divide each side by -0.0025 : t = ln(0.5) / (-0.0025) =
(-0.69315) / (-0.0025) =
<em>t = 277.26 minutes</em>
( 4hrs 37min 15.5sec)
Rounded to nearest tenth: t = 277.3 minutes .
The intensity of the microwave is 10.09 × 10⁵ W/m².
The unit of magnetic induction is the tesla (T). The magnetizing force, which induces the lines of force through a material, is called the field intensity, H (or H-field), and by convention has the units ampere per meter (A m−1) .
The portion of a material's magnetic field that results from an external current and is not intrinsic to the material itself is known as the magnetic field strength, also known as magnetic intensity or magnetic field intensity. It is measured in amperes per meter and represented as the vector H.
Magnetic Field, B = 9.2 × 10⁻⁵ T

Therefore, the intensity of the microwave is 10.09 × 10⁵ W/m².
