Millions of years ago, the Sierra Nevada region began to be uplifted along a crack in Earth's crust. The region on the other sid

e of the crack moved downwards. Which physical feature most likely resulted from such a motion?
Fault block mountain with rough edges and steep cliffs

Fault block mountain with waves, twists, and turns

Answer:  The correct answer is :  Fault block mountain with rough edges and steep cliffs

Explanation:  Snowy saws are an example of a mountain chain blocked by faults. The snowy mountains were formed because the tectonic movement forced some segments of the earth's crust up into irregular pieces and others down.

1. If you look at a reaction equation for a Fischer esterification reaction, you cannot tell where the oxygen comes from (acid o
Yanka [14]

Answer:

Explained

Explanation:

In the experiment, an (18)O-labelled alcohol R('18)OH is used with normal unlabeled carboxylic acid RC(16)O2H:

The esterification reaction is:  

(note: the bracketed values are atomic masses)

RC(16)O_2H + R'(18)OH => RC16O18OR' + H_2(16)O

Since the alcohol is the nucleophile in this nucleophilic substitution reaction, it adds to the carbonyl group of the carboxylic acid and the (18)O atom becomes incorporated into the ester product, while the (16)OH group of the carboxylic acid is expelled as H_2(16)O.

By using mass spectroscopy to measure the mass of the ester and water products, it can be shown that each ester molecule contains one (18)O atom and one (16)O atom, while the water molecules contains only (16)O atoms.

This would prove unequivocally that the ester contains one O atom from the carboxylic acid and one O atom from the alcohol, while the water contains only O atoms from the carboxylic acid.

bagirrra123 [75]

Answer:

1) a. Customers requiring AC electric power transmission for powering remote devices which may include a subsea transmission system where power is distributed to subsea devices

b. Customers that utilize commutator-type motors

2) The primary voltage is 150 volts

Explanation:

The parameters given are;

Number of primary winding, N_p = 50 turns

Number of secondary winding, N_s = 150 turns

Voltage in secondary winding, V_s = 450 volts

Voltage in primary winding = V_p

The relation between N_p, N_s, V_s and V_p is as follows;

\dfrac{V_p}{V_s}  = \dfrac{N_p}{N_s}

Which gives;

V_p  = \dfrac{N_p \times V_s}{N_s}

From which we have;

V_p  = \dfrac{50\times 450}{150} = 150 \ volts

The primary voltage = 150 volts.

“Convection is equal to the Conduction plus <br><br>fluid flow.”
zysi [14]

Answer:

Conduction is the transfer of heat by contact, mostly in solids (metals especially) . In conduction, the molecules of the body in contact with the hot body vibrates about a fixed point. The vibration causes collision between these vibrating molecules and their neighboring molecule, causing them to vibrate too; creating a wave of vibrating molecules that transfer the heat along the solid material.

Convection is the transfer of heat in fluids (liquids and gases), that involves the initial heat transfer between a portion of the fluids molecules and the hot body (conduction) at the thermal boundary, and then the eventual movement of that portion of the fluid from that position to a colder part of the fluid. The heated fluid is replaced by a colder fluid (this is due to buoyant forces due to difference in density of the cold and the warm parts of the fluid). This movement ensure thorough mixing of the fluid and the eventual heating up of the entire fluid.

From the above statements one can clearly see that convection is comprised of an initial heat transfer by conduction at the thermal boundary, followed by movement of the fluid molecules.
