How do volcanologists predict volcanoes? Earthquakes. Moving magma shakes the ground, so the number and size of earthquakes increases before an eruption. A volcano that is about to erupt may produce a sequence of earthquakes. Scientists use seismographs that record the length and strength of each earthquake to try to determine if an eruption is […]
What is the process of a muscle contraction?
What is the process of a muscle contraction? Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed. What determines the strength […]

What will be my mass if my weight is 50 kg?
What will be my mass if my weight is 50 kg? However, WEIGHT does vary given the gravitational well. A mass of 50⋅kg has a WEIGHT of 50⋅kg×9.81⋅N⋅kg−1=490.5⋅N on the earth, but a weight of 50⋅kg×1.622⋅N⋅kg−1=81.1⋅N on the moon…… What is a healthy weight for a 4 11 female? Height and Weight Chart Height Weight […]
Do metallic bonds dissolve in water?
Do metallic bonds dissolve in water? Metallic bonds are not soluble in water because: They are held together by strong metallic bonds and so no solvent to solute attractions could be stronger than these, so these substances are insoluble also they don’t have the necessary intermolecular forces (namely hydrogen bonds) that are present in water. […]
Does grass stop erosion?
Does grass stop erosion? Grasses native to your region will help build soil stability. Native grasses grow long roots that tie the topsoil and subsoil together. Buffer strips, or swathes of native species, are a great way to reduce erosion and sedimentation. An added bonus is using plants that can attract pollinators and increase biodiversity. […]
What is the fastest maglev train in the world?
What is the fastest maglev train in the world? The highest-recorded maglev speed is 603 km/h (375 mph), achieved in Japan by JR Central’s L0 superconducting maglev on 21 April 2015, 28 km/h (17 mph) faster than the conventional TGV wheel-rail speed record. Which country has the fastest train? Countries With The Fastest Trains China […]
What is the change in velocity per time?
Does sonar affect fish?
Does sonar affect fish? It is a finding that Popper says “should not be extrapolated to other fish species or the effects of other sound sources.” There is considerable concern that human-produced (anthropogenic) sounds added to the environment could have damaging effects on marine life. What is the basic principle of sonar? Sonar are electronic […]
