of a pen-cil. write a linear egnation. in 2 variables to represent the Statement​

Answer 1

Answer:

ANSWER IS 10FFFFFFFFFIf the mucus is not secreted by the gastric glands then the stomach wall will be destroyed by the acid, since the mucus protects the stomach wall from hydrochloric acid

Answer 2

Answer:

2

Step-by-step explanation:

`rArr v = sqrt(bR) t (dv)/(dt) = sqrt(bR)`

For circular motion work done by normal force is zero. For tangential forces.

`F_(t)=m(dv)/(dt)=m sqrt(bR) P=F_(t).v = F_(t) v cos theta`

as `theta = 0^@`, `P = F_(t) v = mbRt`

Average power `= (underset(0) overset(T) intP(t)dt)/(underset(0) overset(T)int dt) = underset(0) overset(T) int(mbRTdt)/(T)`

=`(mbR(t^(2)//2)_(0)^(T))/(T) = (mbRt)/(2)`.
