hints: The flask will be filled with water (at a constant rate of 500 gallons per minute). It will take me exactly 10 minutes to escape from the chains. The diameter of the tank at 1 foot intervals. I am 5 feet 9 inches tall, and I'm pretty skinny so that you can ignore both my volume and the volume of the stool in your analysis. A gallon is equal to 0.13368 cubic feet.  You can think of the volume and the height of the water as functions of time. You can easily find an expression for V (t), and then use your expression for volume in terms of height to solve for h(t). after 10 minutes amount of water in the tank=66.84 ft3 t=69.3 minutes h(t)=e66.84t/100?  -1 h(10)=e66.84(10)/100?  -1=7.39 ft  Height of stool=1.64 ft Height of water in the tank=7.39 ft Questions: show work How fast is the water rising?  I would like to know how long I will have to hold my breath during the last part of the stunt.

Why do parachutists 'hit and roll'?

What’s the correct answer please?

The solution (298.349) is incorrect as well.

13. The amount of heat (Hth, thermal energy) stored in rocks, m = 500 kg, S = 840 J/(kg °C), Tfinal =50°C, Tinitial = 40°C is: ·Hth = 19*10E(6) Joules. ·Hth = 4.2 * 10E(6) Joules. %3D ·Hth = 4.2*10E(4)Joules. %3D

Describe processes occur in a certain direction, and not in the reverse direction.
