Water is leaking out of an inverted conical tank at a rate of 11700 cubic centimeters per min at the same time that water is being pumped into the tank at a constant rate. The tank has height 8 meters and the diameter at the top is 6 meters. If the water level is rising at a rate of 26 centimeters per minute when the height of the water is 5 meters, find the rate at which water is being...

Also, a cube of unknown metal measures 1.8 in by .60 in by 1.2 in and has a mass of 189.65 g. What is the identity of the unknown metal? must show work for both
What would be the volume (in cubic centimeters) of such a bacterium, assuming that it is spherical? the diameter of the bacterium is 1.0 um Express your answer using two significant figures. 5.2 and 5.2x10^-13 were incorrect when typed in the answer box
A cement truck delivers mixed cement to a large construction site. Let x represent the cycle time in minutes for the truck to leave the construction site, go back to the cement plant, fill up, and return to the construction site with another load of cement. From past experience, it is known that the mean cycle time is μ = 50 minutes with σ = 16 minutes. The x distribution is approximately normal. (a) What is the probability that the...
You have a large test tube in your drawer in lab. Its volume is 56.2 cubic centimeters. You performed the volume measurement of the test tube and found it to be 54.4 cubic centimeters. What is the percentage error of your measurement?
Item 2 What would be the volume (in cubic centimeters) of such a bacterium, assuming that it is spherical? Express your answer using two significant figures. Bacteria vary somewhat in size, but a diameter of 2.1 am is not unusual. cin Submit X Incorrect; Try Again; 2 attempts remaining Part B What would be the surface area (n square millimeters) of such a bacterium, assuming that it is spherical? Express your answer using two significant figures. ΑΣφ mm2
12. The first few hours after cement and water are mixed are called the dormant/induction period (stage II). At the end of the dormant period, the concrete sets. The popular theory to explain the dormant period is called nucleation- control/nucleation-dissolution theory. (a) Briefly describe the nucleation control theory. (6' Points) (b) What is the effect of adding calcium salt when mixing concrete on the dormant period and explain it using nucleation control theory? (6' Points)
Suppose that the volume of a rectangular based prism is 244 cubic cm. If a pyramid has the same rectangular base and height as the prism, what is the volume of this pyramid? Round your FINAL ANSWER to the nearest 0.1 cubic cm.
1.)Equal masses of water and ethylene glycol (C2H6O2) are mixed. At what temperature will the mixture freeze? The molal freezing point constant for water is 1.86 ºC/m. 2.)The vapor pressure of a liquid depends on? 3.)How many atoms are in a body centered cubic lattice?
One cubic centimeter of a typical cumulus cloud contains 360 water drops, which have a typical radius of 10 μm. (a) How many cubic meters of water are in a cylindrical cumulus cloud of height 3.2 km and radius 1.1 km? Answer in m^3. (b) How many 1-liter pop bottles would that water fill? (c) Water has a density of 1000 kg/m3. How much mass does the water in the cloud have? Answer in kg.
