Answer:
58.703 ft/centuri
Explanation:
Length of the hair grow, l = 0.49 mm
Time to grow, t = 1 day
Convert mm into feet.
We know that, 1 mm = 0.00328 feet
So, 0.49 mm = 0.49 x 0.00328 = 0.0016072 ft
Convert day into century.
We know that, 1 century = 36525 days
So, 1 day = 1 / 36525 centuri
growth rate of hair =
= 58.703 ft/centuri
<span> Archimede's principle states that a body immersed in a fluid is buoyed up by a force (buoyant force) equal to the weight of the fluid displaced by the body.
So If I place a 5 oz rock into a glass of water, and 5 oz of water is displaced, the rock therefore weighs 5 oz</span>
Answer:
Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. Pure ethanol freezes at -115 degrees C, while mercury freezes at -38 degrees C.
Explanation:
It is less durable because alcohol evaporates faster than mercury. It cannot measure high temperature because of a low boiling point. It wets the walls of the thermometer, which can adversely impact the accuracy of readings
