Answer:

Explanation:
Given:
<u>the thermal resistance in the form of </u>


where:
are the thickness of the respective bricks
are the respective coefficient of conductivity
temperature inside the house, 
temperature outside the house, 
area of the wall, 
Since the bricks and insulation are used to construct a wall then they must be used in series for better shielding.
<u>Using Fourier's law:</u>


in series the resistances get add up



The answer is B I had to answer this question one time
Answer:
100
Explanation:
= Resistivity of axon
r = Radius of axon
t = Thickness of the membrane
= Resistivity of the axoplasm
Speed of pulse is given by

So, radius is given by

If radius is increased by a factor of 10 new radius will be

So, The radius will increase by a factor of 100.
Answer:
Gravity
because it's factorised by mass of a body.
For other forces, they deal with charges of negligible mass and weights
Answer: reaction force = -558N
Explanation:
w = f = 558N
since action force and reaction force are equal in magnitude and opposite in direction,
reaction force = -(f)
reaction force = -558N
if that helps.
