As per the question the first atom has 1 valence electron.
The second atom has 7 valence electrons.
The two atoms come closer and combined to form a substance.
Atoms having one valence electrons will be considered as electropositive and the atoms having seven valence electrons are considered as electronegative .
As per the octet role,every atom tends to possess eight electrons in their valence shells to satisfy the inert gas configuration to be stable.
Here the atoms having one valence electrons will lose one atom and atoms having seven electrons will accept this electron .In this way both the atoms will satisfy inert gas configuration. The atom which will lose electrons tends to form cation and the atom which will accept electrons tends to form anion.So there is the chance of formation of ionic bond.
The electronegative atom can not emit seven electrons as it will require more ionization energy.The atom having one atom in its valence shell can not accept one electron from the other atom as by doing so they will lose their stability.
There will be no sharing of electrons here.It is because the atoms having one atom in their valence shell has low ionization energy and atoms having seven electrons in their valence shells have high electron affinity.Here ionic bond is favorable not covalent bond.
Hence the option C is right.
Answer:
The total momentum of the system is 1.45 kg*m/s.
Explanation:
The total momentum of the system is given by:
Where:
m: is the mass
v: is the velocity
d: is for duck
b₁: is for baby duck one
b₂: is for baby duck two
b₃: is for baby duck three
Therefore, the total momentum of the system is 1.45 kg*m/s.
I hope it helps you!
The problem can be solve using the formula
τ=r F sin(θ)
Where
τ is the torque,
r is the distance from where the pivot is to where the force
is,
F is the force exerted, and
θ is the angle between the force and radius
τ=(0.15m) (150N) sin(30) = 11.25 Nm

Answer:
(E) none of these.
Explanation:
first that all we need the meaning of a Watt
<em>" is a unit of power. In the International System of Units (SI) it is defined as a derived unit of 1 </em><em>joule</em><em> per </em><em>second</em><em>,[1] and is used to quantify the rate of </em><em>energy</em><em> transfer." </em>
<em>definition taken from wikipedia.org</em>
now with this concept we have that:
100 W means 100 J/s .Therefore it uses 100 J energy per second
therefore on the answers don't mention this three terms together
Joules, energy and second so the answer must be.
(E) None of these
