To solve this problem we must simply resort to Newton's second law as well as the relationship between pressure and force as a physical unit applied in a given area.
In mathematical terms the Weight can be expressed as
Where,
m = mass
g = Gravitational Acceleration
We have the mass and the gravitational acceleration therefore the Weight is
Replacing we have
In this way the pressure exerted according to the active Area is,
Therefore the pressure difference between the lower and upper surface of the wings is 9.14kPa
Answer:
9.67 kg
Explanation:
If the gauge pressure is 43 atm, the absolute pressure is 44 atm
p1 = 44 atm = 4.46 MPa
If the gauge pressure is 29.4 atm, the absolute pressure is 30.4 atm
p2 = 30.4 atm = 3.08 MPa
The ideal gas state equation is
p * V = m * R * T
We can set two eqaution for these two times
p1* V1 = m1 * R * T1
p2* V2 = m2 * R * T2
SInce V1 = V2 and T1 = T2
p1 = m1 * R
p2 = m2 * R
Rearranging
R = p1 / m1
R = p2 / m2
Equating:
p1 / m1 = p2 / m2
m2 = m1 * p2 / p1
m2 = 14 * 3.08 / 4.46 = 9.67 kg
I think it's A electrical impulses from the ear
Answer:
A. Its unique strength allows predetermined engineering stresses to be placed in members to counteract stresses that occur when the unit is subjected to service loads
Explanation:
Prestressed concrete is a structural material that allows for predetermined, engineering stresses to be placed in members to counteract the stresses that occur when they are subject to loading.
It combines the high strength compressive properties of concrete with the high tensile strength of steel.

Then the correct answer is:
A. Its unique strength allows predetermined engineering stresses to be placed in members to counteract stresses that occur when the unit is subjected to service loads
Insulators are the materials that are bad conductors of heat/electricity.insulation is tge pricess of covering any thing with such materials in order to prevent heat or electricity.
