Which sentence from the article supports the devastation from pyroclastic flows and surges? a. "on that night an explosive eruption tore through the summit and spewed approximately 20 million cubic meters of hot ash and rocks across the snow-covered glacier." b. "these materials were transported across the snow pack by avalanches of hot volcanic debris (pyroclastic flows) and fast-moving, hot, turbulent clouds of gas and ash ( pyroclastic surges)." c. "as these floods of water descended the volcano, they picked up loose debris and soil from the canyon floors and walls, growing both in volume and density, to form hot lahars." d. "in a few short minutes most of the town was swept away or buried in a torrent of mud and boulders, and three quarters of the townspeople perished."

The sentence from the article that supports the devastation from pyroclastic flows and surges is "these materials were transported across the snow pack by avalanches of hot volcanic debris (pyroclastic flows) and fast-moving, hot, turbulent clouds of gas and ash ( pyroclastic surges)."

Explanation:

This sentence from the article talks about the devastation that comes out of pyroclastic flows and surges as it describes how this phenomenon happens, besides it has strong words that talk about an invasive and aggressive attack such as avalanches, hot volcanic, fast-moving, turbulent clouds, they represent hostility.

in the spreadsheet, click on a cell, then type the numbers or text you want and press enter or tab. to write data to a new line within a cell, press alt + enter. to enter the same data in several cells at the same time you must select the cells in which you want to enter the same data, in the active cell write the data and press ctrl + enter.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
