Answer:
The right approach will be Option C "Group 12".
Explanation:
- A table that further arranges the chemical components in addition to expanding the electron configuration. Elements possessing identical characteristics are positioned in almost the same section (column or group), although elements in almost the same row become positioned with a similar amount of electron spheres.
- Group 12 components therefore partially replaced (n − 1)d subshells, and therefore aren't metals, technically accurate. However, although much their chemistry seems to be comparable to something like the components throughout the d block which includes establishing themselves.
Some other options in question are not relevant to something like the given scenario. Because then the option here is just the right one.
Answer:
Explanation:
Time period, T = 50 μs = 50 x 10^-6 s
Frequency is defined as the number of oscillations or vibrations completed in one second.
The reciprocal of time period is called frequency.
f = 1 / T
f = 1 / (50 x 10^-6)
f = 20,000 Hz
Angular frequency, ω = 2 x π x f
ω = 2 x 3.14 x 20,000
ω = 125600 rad/s
Answer:
0.85 A
Explanation:
the effective current is 0.85 A
Answer:
The focal length of this lens is f = 0.55 D
Explanation:
Given that the far point of an eye ( d )= 180 cm = 1.8 m
We know that focal length of lens is given by
Put the value of d in above equation we get
f = 0.55 D
Therefore the focal length of this lens is f = 0.55 D
