Why do stores still sell those 1.5 volt batteries that are like three times the size of other 1.5 volt batteries. What is the point of having a bigger battery if it's the same voltage? If anything, wouldn't the smaller battery be more favorable?

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

At 12 noon, the count in a bacteria culture was 400; at 4: 00 pm the count was 1200 let p(t) denote the bacteria cou population growth law. find: (a) an expression for the bacteria count at any time t (b) the bacteria count at 10 am. (c) the time required for the bacteria count to reach 1800.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
