The water in a lake is at 5 °C. A diver measures the pressure of the water at two different depths in the lake. He repeats the m
easurements on a different day when the water is at 15°C. The density of the water decreases when its temperature increases. Which combination of depth and temperature produces the greatest water pressure?
The combination of depth at 10 m and the temperature of 15 °C will produce the greatest water pressure.
Explanation:
The pressure in any liquid is directly proportional to the depth of the water body. This is because, the more the depth, the more the buoyant force will be acting on the liquid surface. So if the water is kept constant at 15 °C, the volume is said to increase with increase in temperature as volume is directly proportional to the temperature. The same goes for pressure, the pressure of liquid increases with increase in temperature. So the combination of depth at 10 m and the temperature of 15 °C will produce the greatest water pressure.
The amount of gold atoms could be calculated by dividing the
total weight of the gold with the mass of a single gold atom. Just convert the
given weight to grams then divide it with 3.27x10^-22 grams. The answer would
be 7.22x10^20.
The black means that it is a great emitter/absorber of the electromagnetic spectrum. The electromagnetic radiation is reflected of the white and absorbed nurture black meaning that the temperature of the black tarmac increases to that greater the the white
Relative age-dating involves comparing a rock layer or rock structure with other near-by layers or structures. Using the principles of superposition and cross-cutting relationships, and structures such as unconformities, one can determine the order of geological events.
