What sort of a sensor is a PT100?
A PT100 is a PTC (Positive Temperature Coefficient), which means that it's resistance ascends with it's temperature
How negative buoyancy affect a blimp?
Negative buoyancy is when the gravitational pull on a diver is greater than the buoyant force. This means that the diver is being pulled downward, and that the buoyant force is doing negative work (work that is in the opposite direction of the displacement). Positive buoyancy is the opposite situation in which the buoyant force of the diver is greater than the gravitational pull, which makes the diver move upwards. Usually, a person's weight is slightly more than the weight of the displaced amount of water. For example, a person who weighs 80kg displaces 79dm2 of water, which weighs 79kg, that is, he has about 1kg of negative buoyancy. As for your question whether this negative buoancy is a unique feature for black people, the answer is no. it is related to the person's density.
Why does the elevation gradually decrease away from the ridge axis?
Hot material ascends at the ridge axis form the mantle. It partially melts. The basaltic melts ascend and form 6-7 km of oceanic crust. The seafloor and the underlying mantle then move away from the ridge axis. The material cools from top down. As it does it contracts thermally and becomes more dense. The vertical contraction of the material and the increased load on the underlying mantle causes the seafloor to subside. The weight of the overlying water also causes subsidence. To the first order, the predicted depth to the seafloor increases with the square root of age from the ridge axis. This in fact occurs and was strong evidence for the reality of seafloor spreading in the late 1960s. Note that Lord Kelvin was on the trans-Atlantic cable project. He crossed the Charlie-Gibbs fracture zone rather than the ridge axis. The square-root relationship was not evident. Wegener also considered the process to some extent, but ended up with continents moving as rafts rather than with seafloor spreading. See paper for technical derivation and some early references. 2011 Sleep, N. H., Small-scale convection beneath oceans and continents. Chi. Sci. Bull., 56(13), 1292-1317, DOI: 10.1007/s11434-011-4435-x.
an aircraft descends 150m from an altitude of 650m to avoid turbulence. The plane ascends 830m after the descent. at what altitude is the plane flying?
1330m
How is decompression sickness related to pressure?
Divers breathing compressed gases at depth are themselves under pressure. For each 33 feet/10 meters that a diver descends, they add approximately 1 atmosphere of pressure to their body. When they breathe gases whilst their bodies are under this pressure, the gases dissolve into their bodies tissues. When they ascend, the pressure is relieved, and gases are released. Provided that diver ascends sufficiently slowly, the gases are released slowly and no problems result. But if the diver ascends too slowly without allowing the gases to expire at a slow enough rate, then the diver will suffer decompression sickness when gas bubbles form in the diver's tissues and blood.
What is the median of 28 31 31 30 30?
Median is the middle number of a list that ascends or descends in order. 30 would be the median of 28, 30, 30, 31, 31.
What is a melodic scale in music?
A melodic minor scale is a minor scale where the sixth and seventh are raised by a half step as the scale ascends; however, the melodic minor scale is played exactly the same as a natural minor scale as it descends.

What are the release dates for Alice Ascends - 2010?

Example of a sequence?
a sequence is a pattern of numbers that ascends or descends in a same way eg. 1,3,5,7,... you add 2 eg. 1,4,9,... you square the term nth term = nxn 1x1=1 2x2=4 3x3=9 there are many sequences and many formulas to calculate terms hope that helped

How are winds affected by areas of high pressure?
In zones where air ascends, the air is less dense than its surroundings and this creates a center of low pressure. Winds blow from areas of high pressure to areas of low pressure, and so the surface winds would tend to blow toward a low pressure center. In zones where air descends back to the surface, the air is more dense than its surroundings and this creates a center of high atmospheric pressure. Since winds blow from areas ofhigh pressureto areas oflow pressure, winds spiral outward away from the high pressure. The Coriolis Effect deflects air toward the right in the northern hemisphere and creates a general clockwise rotation around the high pressure center. In the southern hemisphere the effect is just the opposite, and winds circulate in a counterclockwise rotation about the high pressure center. Such winds circulating around a high pressure center are calledanticyclonic windsand around a low pressure area they are calledcyclonic winds.
