Answer:Height = 30 inches
Mass of water / Volume of water x Gravity constant for Earth x Density of Water. This cancels out to give us mass/volume, which is then cancelling mass, giving us the final unit of length/area (in this case inches).
Explanation:
Height = 30 inches.
Units cancelled:
30/30 x 9.8 x 0.9971 = 30/39.97
The final units are in inches!
2. Determine the weight (in pounds) that an ice cube at 32°F will displace when placed in water at 75°F.
Weight of ice cube / Volume of water x Gravity constant for Earth x Density of Ice = Weight displaced by ice cube in pounds
Weight of ice cube / Volume of water x Gravity constant for Earth x Density of Ice = 0.5/75 x 32 x 0.92 = 0.5/22.67
The final units are in pounds!
3. Determine the mass (in grams) of an ice cube at 32°F when placed in water at 75°F (assume no change in volume).
Mass of Ice Cube / Volume of Water x Gravity constant for Earth x Density of Ice = Mass of ice cube in grams
Mass of Ice Cube / Volume of Water x Gravity constant for Earth x Density of Ice = 0.5/75 x 32 x 0.92 = 15/22.67
The final units are in grams!
In the case above, It will take more time for a tooth of wheel B and C to make a full turn (slower) than it will for a tooth of wheel A.
<h3>What are gear wheels?</h3>
A gear wheel is known to be a kind of a wheel that is known to be made up of a teeth and/or cogs that is known to function with those of other aspect of the wheel or part.
Note that in the above case, lets use a scenario that Wheel P has 5 teeth. Wheel M has 3 teeth and wheel N has 1 teeth. If wheel P makes a full turn, wheel M turn will be slower as well as wheel N which will take more time.
Therefore, In the case above, It will take more time for a tooth of wheel B and C to make a full turn than it will for a tooth of wheel A.

I’m just here for points because I have test and I need them lol
Answer:
58.44 g/mol The Molarity of this concentration is 0.154 molar
Explanation:
the molar mass of NaCl is 58.44 g/mol,
0.9 % is the same thing as 0.9g of NaCl , so this means that 100 ml's of physiological saline contains 0.9 g of NaCl. One liter of physiological saline must contain 9 g of NaCl. We can determine the molarity of a physiological saline solution by dividing 9 g by 58 g... since we have 9 g of NaCl in a liter of physiological saline, but we have 58 grams of NaCl in a mole of NaCl. When we divide 9 g by 58 g, we find that physiological saline contains 0.154 moles of NaCl per liter. That means that physiological saline (0.9% NaCl) has a molarity of 0.154 molar. We can either express this as 0.154 M or 154 millimolar (154 mM).
