As per the question, the resistor system contains two resistors.
The two resistors are denoted as
We are asked to calculate the effective resistance in terms of
The two resistors can be connected in two ways.
CASE-1: Let the resistors are connected in series.
When the resistors are connected in series, the effective resistance is the algebraic sum of the individual resistors.
Hence, the effective resistance [ans]
CASE-2: Let the resistors are connected in parallel.
The effective resistance is calculated as follows-
⇒ [ans]
Answer:
the function varies linearly with the radius of the disk, so the smallest period is zero for a radius of zero centimeters
Explanation:
This system performs a simple harmonic movement where the angular velocity is given by
w = √ k / I
Where k is the constant recovered from the axis of rotation and I is the moment of inertia of the disk
The expression for the moment of inertia is
I = 1/2 m r²
Angular velocity, frequency and period are related
w = 2π f = 2π / T
Substituting
2π / T = √ k / I
T = 2π √ I / k
T = 2π √ (½ m r² / k)
T = (2π √m / 2k) r
We can see that the function varies linearly with the radius of the disk, so the smallest period is zero for a radius of zero centimeters
Answer:
Explanation:
When we want to decipher the chemical behavior of atoms, we consider the electrons in such an elements. Electrons are negatively charged particles and they are the reasons why chemical reactions proceeds. In nuclear reactions, the nucleons which are the protons and neutrons takes center stage.
For chemical bonds to form, atoms would want to mimic the configuration of the noble gases by either gaining or losing electrons. Some atoms also would share their electrons in order to have a more stable configuration.
Chemical bonds are formed using the valence or outermost shell electrons. The valence shell electrons have relatively low ionization energy compared to those of the inner orbitals.
For an atom with atomic number 12, its electronic configuration would be 2,8,2 with the sublevel notation written as 1S²2S²2P⁶3S²
This atom has 2 valence electrons in its valence shell.
The closest group 8 element to atom with atomic number of 12 is neon. Neon has an atomic number of 10 and its configuration is given as 2,8.
For our atom to be like Ne, it must be ready to lose two of the valence electrons.
Atom-12 would prefer to form an ionic bond because of its high electropositivity i.e ability to lose electrons.
(-2,4). (1,3)
(3-4)/(1+2)= -1/3 is the slope
