The sun shines on a 300-ft2 south-facing wall, maintaining that surface at 98°f. temperature varies linearly through the wall and is 77°f at its other surface. the wall thickness is 6 inches and its thermal conductivity is 0.04 btu/h · ft °r. assuming steady state, determine the rate of exergy destruction within the wall, in btu/h. let t0 = 77°f.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
