Answer:
Wavelength is 10m
Explanation:
To solve this problem, we use the formula for wavelength
Wavelength = wave velocity / frequency
Wavelength = 50m/s / 5Hz
= 10m
The element that has the smallest atomic radius is <u>titanium</u>
<em><u>explanation</u></em>
- Calcium,potassium, scandium and titanium are in period 4 in the periodic table.
- Generally the atomic radius decreases across the period (from the left to the right) . This is because across the period there is increase in nuclear charge which make electrons been strongly attracted to the nuclear.
- Titanium is in atomic number 22 thus it has more nuclear charge that calcium,potassium and scandium therefore titanium has the smallest atomic radius.
Bose Einstein condensation occur at temperature very close to absolute zero i.e 273.15 degrees centigrade.. Under such conditions, large quantity of Boson occupies the lowest quantum state, at which point microscopic quantum phenomena becomes apparent macroscopically. A BEC is formed by cooling a gas of extremely low density about one hundred thousandth the density of normal air, to ultra low temperature.
Answer:
C). Half-reactions with SRP values greater than zero are spontaneous.
Explanation:
SRPs or Standard Reduction Potentials are characterized as the ability of a probable distinction among the anode and cathode of a usual/standard cell. It aims to examine the capacity of chemicals to reduce themselves.
The third statement asserts <u>a true claim regarding the SRPs(Standard Reduction Potentials) that the 'half-reactions which take place with the SRP possesses the values higher than zero and they are unconstrained</u>.' The other statements are incorrect as they either show the estimation of SRPs more than 0 or display them as being restricted. Thus, <u>option C</u> is the correct answer.
