Of those using Brand A in any month, 70% continue to use it in the following month, 20% switch to Brand B, and 10% switch to Brand C.

Of those using Brand C in any month, 70% continue to use it in the following month, 10% switch to Brand A, and 20% switch to Brand B. (a) What is the stochastic matrix P for this situation?

the device is called “ rocket engine”

i think the answer would be b

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

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.
