Answer:
Hydrogen bond.
Explanation:
It is an intermolecular bonding interaction between two molecules of different electronegative values or bonding between lone pairs of electron rich molecules.
Hydrogen-bonding forms in liquid water as the hydrogen atoms of one water molecule are then attracted towards the oxygen atom of a neighboring water molecule resulting in a general proton shared by two lone electron pairs.
Answer:
OPTION (C)
Explanation:
m(magnification) = -0.4 means a real, inverted and diminished image is formed in front of the mirror.
Explanation:
If Team A is on the left, B is on the right
if the force is constant, it means that the effort applied is equal.
So Team B is pulling 5000N to the right.
Answer:
True
Explanation:
The normal line is defined as the line which is perpendicular to the reflecting surface at the point where the incident ray meet with the reflecting surface.
The angle of incident is defined as the angle which is subtended by the incident ray with respect to the normal ray by consider the normal ray as the base line and angle is measured from the point where incident ray is incident on the reflecting surface of the mirror.
Similarly reflecting ray can be defined as the ray which is reflected after the incident of a ray and the angle subtended by the reflecting ray is measure with respect to normal ray by considering normal ray as a base line.
Therefore, the normal ray is the perpendicular line to the reflecting surface at the point of incidence.
An alpha particle is identical to a helium nucleus. The correct option
among all the options given in the question is option "A". In case of
both the alpha particle nucleus and helium nucleus, there are two protons and two neutrons. Alpha particles are generally formed during the process of alpha decay. They can also be produced in other ways.
