The appropriate response is the Aneroid barometer. This kind of gauge has an incompletely cleared chamber that progressions shape, packing as barometrical weight increments and growing as weight declines.

I hope the answer will help you.

HELP PLS! :/
zlopas [31]

Explanation:

formula: Vi = Vf - (at)

Vi: intial velocity

Vf: final velocity

a: acceleration

t: time

fill in formula with the numbers you are given

Vi= 41.6m - ((9.81 m/s^2)(1.89s))

parenthesis first according to pemdas

Vi= 41.6m - 18.54m/s

Answer: 23.06m/s

disclaimer: I havent done physics in awhile so I have no idea if this is right. just an attempt to help steer you in the right direction hopefully. good luck

An elevator is moving upward at 0.91 m/s when it experiences an acceleration 0.31 m/s2 downward, over a distance of 0.61 m. What
alexgriva [62]

Given:

u= 0.91 m/s

a=0.31m/s∧2

s= 0.61 m

s = ut +1/2(at∧2)

where s is the displacement of the object

u is the initial velocity

t is the time

a is the acceleration

Substituting the values

0.61=0.91×t +(0.31 ×t∧2)/2

0.61=0.91 t + 0.155 t∧2

t=0.61 secs

Consider the equation

<u>v=u +at </u>

where v is the initial velocity

u is the initial velocity

a is the acceleration

t is the time

Substituting the values we get

v= 0.91 +(0.31×0.61)

v= 1.099 m/s

Explain the difference between how intrusive and extrusive igneous rock form and how those formation processes affect the minera
rusak2 [61]

Extrusive molten rocks are formed from lava while the intrusive molten rocks are formed from magma.

<u>Explanation:</u>

Extrusive molten rocks originate from lava, framing at the outside of the Earth and cooling rapidly, which means they structure little precious stones. Intrusive volcanic rocks originate from magma, shaping profound underground and taking more time to cool, which means they structure bigger crystals.

Intrusive molten rocks are framed when magma cools gradually underneath the surface, while extrusive rocks are shaped when magma cools quickly at the surface.
