**Please Help. ASAP** Rearrange the formula so the letter in parenthesis is the subject. Show your work as well.

1) v-u/a = t, (v)

2) y-x^2/x = 3z, (y)

3) x+xy = y, (x)

4) x+y = xy, (x)

5) x = y+xy, (x)

6) E = (1/2)mv^2-(1/2)mu^2, (u)

7) (x^2/a^2)-(y^2/b^2) = 1, (y)

8) ay^2 = x^3, (y)

On a average work day more than work place firs are reorted

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
