Answer:
Mt. Pinatubo is one of the contrasting volcanoes that erupted violently in the year 1991, being the second strongest volcanic eruption that took place on earth in this entire century.
The 3 hypothesis that was proposed in order to describe the seismic activity of Pinatubo includes-
- The magma rising upward to the surface from the interior of the earth, erupting through the crater of the volcano.
- The eruption led to the releasing of a large number of volcanic gases into the atmosphere.
- The earthquakes are produced due to the continuous tectonic activities that are primarily caused when the earth's crust moves over the layer of viscous asthenosphere.
A large number of volcanic gases are released such as sulfur dioxide (SO₂), methane (CH₄), Hydrogen sulfide (H₂O), Carbon monoxide (CO), and other gases, due to the formation of convection currents and rising up of magma from the mantle, creating volcanic eruptions at the surface
C would be the only logical answer if you really think about what it’s saying about the instrument.
By dissolving salt in seawater the seawater acts as the solvent. The definition of a solvent is: liquids that dissolve other substances.
Answer:
2.33*10^-15 s
Explanation:
We need to estimate the period of oscillation of an electron that bounced up/down due to the effects of a passing packet of red light. The period of oscillation is the wavelength of the red light divided by the speed of the red light. We know that:
V = f*λ
where V = speed of the red light = 3*10^8 m/s
f = frequency = 1/T where T is the period of oscillation in seconds (s)
λ = the wavelength of the red light = 0.7*10^-6 m
Thus:
V = λ/T
T = λ/V = (0.7*10^-6)/(3*10^8) = 2.33*10^-15 s
In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.
