Q4.A qualitative measure of the stability of an ionic compound is provided by
Answer : Option CExplaination / Solution:
Lattice energy is an estimate of the bond strength in ionic compounds. It is defined as the heat of formation for ions of opposite charge in the gas phase to combine into an ionic solid.
The stability of ionic bond is directly propotional to lattice energy.
Q6.An object is said to be in uniform motion in a straight line if its displacement
Answer : Option BExplaination / Solution:
Uniform motion is the kind of motion in which a body covers equal displacement in equal intervals of time. It does not matter how small the time intervals are, as long as the displacements covered are equal.
If a body is involved in rectilinear motion and the motion is uniform, then the acceleration of the body must be zero.
Q9.The waves on the surface of water are of two kinds:.
Answer : Option DExplaination / Solution:
As capillary & gravity waves are elastic waves or mechanical waves which require medium for their propagation.
Hence they are using the elastic behaviour of water.
Hence
The waves on the surface of water are of two kinds:
capillary waves and gravity waves
