Although hand specimen identification is some what of an art; igneous rocks are classified using two critiria:
•Texture
•Chemical and mineral composition
Most of the time the rock name, such as basalt or granite, reflects the chemical composition. The minerals and textures are used as adjectives that modify the rock name. You might see a name like an olivine basalt or a quartz porphyry rhyolite.

Thomson's experiments accounted for: the mass of the electron the fundamental charge the force on a current-carrying wire the el
gogolik [260]

Thomson experiment he calculated the charge to mass ratio just be passing the fundamental charge through a tube

He calculated the charge to mass ratio just by finding the deflection of charge while it is passing through the constant electric field

so here we will use the deflection as following

let say it passes the field of length "L"

so here we have

t = \frac{L}{v}

now in the same time if it deflect by some distance

\delta y = \frac{1}{2}at^2

\delta y = \frac{1}{2}{eE}{m}t^2

now by solving this equation we can find e/m ratio

so here correct answer will be

the electron's charge-to-mass ratio

Which wavelength would scientists use to measure the molecular structure of H2O?
Ne4ueva [31]

Answer:

To find out what water is made of, it helps to look at its chemical formula, which is H2O. This basically tells us that the water molecule is composed of two elements: hydrogen and oxygen or, more precisely, two hydrogen atoms (H2) and one oxygen atom (O).

wo kids are on a seesaw. The one on the left has a mass of 75 kg and is sitting 1.5 m from the pivot point. The one on the right
Anastaziya [24]

Answer:

4.5 Nm (Anticlockwise)

Explanation:

Let the 75 kg kid is sitting at the left end and the 60 kg kid is sitting on the right end.

Anticlockwise Torque = 75 x 1.5 = 112.5 Nm

clockwise Torque = 60 x 1.8 = 108 Nm

Net torque = Anticlockwise torque - clockwise torque

Net Torque = 112.5 - 108 = 4.5 Nm (Anticlockwise)

There are pluses and minuses to being a competitive person.<br> True <br> False
melomori [17]
True, because being a competitive person means that you like challenging yourself to do more things, but if you’re really competitive you might challenge yourself too hard, and might hurt yourself, which will make you not want to really compete with anything anymore
