At first observation, the airplane is at distance from the station and at angle above the horizon. The airplane is tracked through an angular change in the vertical eastâwest plane; its distance is then. Find the (a) magnitude and (b) direction of the airplaneâs displacement during this period.n elevator without a ceiling is ascending with a constant speed of 10 m/s. A boy on the elevator shoots a ball directly upward, from a height of 2.0 m above the elevator floor, just as the elevator floor is 28 m above the ground. The initial speed of the ball with respect to the elevator is 20 m/s.
Two or three years ago, building a DIY sensory deprivation tank at your home was a no-brainer unless you had unlimited resources to spend 10-12K (at least) on a commercial float tank adapted for your home. With transportation and construction costs the sum could go up to 15-20K.
Your situation in your area will change the economics of getting oxygen. The tanks are almost never lifted. They are rolled by tipping slightly and rolling along on the edge of the bottom. K-tanks are the most cost effective to refill mostly because they are the most used size. Here in the Seattle/Tacome area a K-tank costs about $190.00 to buy. I don't know the rental cost. I pay $14.00 per tank to refill and that's on a 'lampworkers/glass blowers' account that is used by a bunch of people all unrelated/unknown to each other.
