Whenever these are an alarming due to a foreign antigen, the Helper T cells, Memory T cells, and Cytotoxic T cells are being produced. Helper T cells to recognize the specific foreign antigen that is entering the body, Memory T cells to remember the specific foreign antigen that is attacking, and Cytotoxic T cells that are for the destruction of the foreign cells and produce cytokines to attract macrophages
Answer:
Explanation:
Let T be the tension in the cord.
Impulse by cord = change in momentum of block A .
T x 5s = 10 ( 2 -0) = 20
T = 4 poundal .
acceleration of block B = 2 / 5 = 0.4 m /s²
Net force applied on A = m ( g + a ) where m is mass of block B , a is acceleration of block B .
= 8 ( 32 + .4 ) = 259.2 poundal
Frictional force on block A = 259.2 - 4 = 255.2 poundal
μ x 10 x 32 = 255.2
320μ = 255.2
μ =0 .8 .
Change in temperature
A calorimeter directly measures temperature change and this information, along with the substance's mass and specific heat, is used to calculate the amount of heat.<span />

Answer:
The extent to which it would stretch is 
Explanation:
From the question we are told that
The initial length is 
The area is 
The Young modulus of the steel is 
The tension is 
The Young modulus is mathematically represented as
Where 
is the stress which is mathematically represented as
Substituting values
And e is the strain which is mathematically represented as
Where 
The extension of the steel string
Substituting these into the equation above
Substituting values
