are 4 non examples of condensation .
What is condensation ?
Condensation, the separation of a liquid or solid from a vapor, generally occurs on surfaces that are cooler than the adjacent gas. A substance condenses when the pressure exerted by that vapor exceeds the vapor pressure of the substance's liquid or solid phase at the temperature of the surface on which condensation is occurring. As the steam condenses, heat is released. If this heat is not removed, the surface temperature will rise until it matches the surrounding steam.
If the air does not contain small particles, so-called aerosols, condensation will only occur if the air is extremely supersaturated with water vapor.

why were alpha particles the only radioactive particle that could have been used in rutherfords gold foil experiment
Alpha particles are the only radioactive particle that could have been used in the Rutherford gold foil experiment because they are produced naturally by radioactive nuclides that are alpha emitters and so a steady supply was easy to obtain.
As alpha particles do not travel very far from their radioactive source. They cannot pass through a piece of paper, clothes, or even the layer of dead cells which normally protects the skin.
Rutherford used alpha particles in his gold foil experiment in part because his previous research on radioactive decay discovered alpha particles. He wanted to test how alpha particles, which are positively charged, would react with various forms of matter.

B) lattice of positive ions in a sea of electrons
C) lattice of neutral atoms with delocalised electrons.
D) lattice of negative ions with delocalised electrons.
Answer:
C) lattice of neutral atoms with delocalised electrons
Explanation:
Fact 1: metals are elements and therefore they contain atoms that are electrically neutral
Fact 2: in all atoms, the electrons are delocalised/ are free moving electrons (as the electrons serve their purpose in different forms depending whether you look at it the chemistry way or physics way)
metals are solid and hence they have a lattice structure

The electronic configuration packing patterns of some elements in group 6b(6) and group 1b(11) reflect the enhanced stability of half-filled and fully-filled sublevels. So option (c) is correct.
What is electronic configuration?The electronic configuration of an element describes how the electrons are distributed in its atomic orbitals. For example, the electron configuration of sodium is 1s²2s²2p⁶3s¹
The three rules that direct the manner in which electrons are to be filled in atomic orbitals are:
Aufbau principle: Electrons must completely fill the atomic orbitals of a given energy level before occupying an orbital of a higher energy level. Electrons fill orbitals in the increasing order of orbital energy level.
Pauli’s exclusion principle: It states that two electrons can never have equal values for all four quantum numbers. Also each subshell of an orbital can have a maximum of 2 electrons and both these electrons must have opposite spins.
Hund’s rule of maximum multiplicity: The subshells in an orbital must be singly occupied before it is doubly occupied. Furthermore, the spin of all the electrons in singly occupied subshells should be the same (to maximize the overall spin).

the karp-flatt metric helps to determine whether the decrease in efficiency is arsing due to higher serial fraction or parallel overhead.
By finding the serial fraction, we arrive to the aforementioned Karp-Flatt metric.
What is Karp-flatt metric ?A measure of code parallelization in systems with parallel processors is the Karp-Flatt metric. This metric exists in addition to Amdahl's law and Gustafson's law as a measure of the level of parallelization of a specific computer code. In 1990, Horace P. Flatt and Alan H. Karp made the suggestion.
The effectiveness of a parallel algorithm operating on a parallel processor can be evaluated in a variety of ways. The Karp-Flatt metric identifies a statistic that highlights performance characteristics that are difficult to identify from other metrics. Amdahl's Law has the following pseudo-"derivation," .
Note that the left hand side reflects a metric quantity rather than a quantity that was derived mathematically, indicating that this is not a "derivation" from Amdahl's law. The analysis above only demonstrates that the Karp-Flatt measure and Amdahl's Law are compatible.
