From the data in the following questions calculate the missing quantity. a) V1 = 22.4L; T = 0°C; T2 = 91°C; V=?L
b) V1 = 125 mL; T1=?; T2 = 25°C; V2 = 100 mL
c) Vi= ? L; T1 = 400 K; T2 = 175 K; V2 = 6.20 L
d) V1 = 250 mL; T = 298 K; T2 = ? K; V2 = 273 mL

what is the question because that is not a question.

connect the batteries in series and hope

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
