Answer: 12.18 u

Explanation: The average atomic mass of an element is calculated by taking the weighted average of the atomic masses of its stable isotopes.

In other words, each stable isotope will contribute to the average mass of the element proportionally to its abundance.

Thermohaline currents are influenced by wind.<br><br> True or false?
tresset_1 [31]

Answer:

FALSE

Explanation:

The under-water deep ocean currents that are generated due to the differences in the water density are generally termed as the thermohaline circulation. It is mainly controlled by the two factors namely the temperature and the salinity. The word 'thermohaline' is directly derived from the temperature (thermo) and salinity (haline).

This thermohaline circulation is considered as the oceanic conveyor belt that allows the water to move under the surface of water at certain depths from the equator to the poles and back from the poles to the equator.

Thus, it is directly associated with the density of the water. It has no relation with the wind.

Hence, the above statement is False.

Light with 4.5 eV of energy hits a metal surface with a work function of 3.2 eV. Will electrons be emitted ? If so how much ener
drek231 [11]

Answer:

Yes, electrons with energy of 1.3ev will be emitted from the metal surface

Explanation:

From Eisenstein's photoelectric equation;

KE= E - Wo

Where;

KE= kinetic energy of the emitted photoelectron = ??

E= Energy of the photon =4.5 ev

Wo= work function of the metal = 3.2ev

KE= 4.5 ev - 3.2 ev

KE= 1.3 ev
