vacuum doesn't pull, pressure pushes b.
500 N/m^2 b.
2 s up and 2 s down the velocity took 2 s to drop to zero (at the peak of the flight) so it must have started at 20 m/s
calculate the pH of a 0.2moldm-3 solution of ammonia at 298K given that Kb for ammonia is 1.8x10-5
It is not a school question. It is a real life question. So let's assume the interest averaged 4 % compounded daily over the 27 years.
$2700 left in an account paying 4% interest would be worth how much today?
$2700 left in a variable rate interest bearing account in 1986 is worth how much today ?
If I left $2700 in a variable rate interest account in 1986, how much is it worth today ?

Two banked curves on a highway have the same radius. Curve A is banked at 13 degrees and highway B is banked at 19 degrees. A car can travel around curve A without relying on friction at a speed of 18 m/s. At what speed can this car travel around curve B without relying on fri...
