complete this sentence. the electrical conductivity of a sample will when the size of the sample increases.

decrease
stay the same
increase
be unable to be determined

increase

explanation:

The electrical conductivity of a sample will increase when the size of the sample increases. the resistance of a conductor is inversely proportional to the area of cross-section when we increase the area of a cross-section of  a conductor   resistivity of the conductor decreases as resistivity is inversely proportional to conductivity  so by increasing area of cross section conductivity of a sample increases

the ecg findings of an acute anterior myocardial infarction wall include: st segment elevation in the anterior leads (v3 and v4) at the j point and sometimes in the septal or lateral leads, depending on the extent of the mi. this st segment elevation is concave downward and frequently overwhelms the t wave.
