Calculate the rate of flow of heat through the insulation, assuming the fibre as a flat slab of area of 1.40 m2

Global warming was a major concern some people do not care global warming is fake it is not real the percentage of it happening  is slight 

Inelastic is the answer your looking for.

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
