magnetization
paramagnetism
diamagnetism
demagnetization
ferromagnetism
Correct answer is C
If diamagnetic substances are placed in a non-uniform magnetic field, then the substances move towards the weaker side of the field from the stronger side.
When a rod of diamagnetic substance is suspended in a uniform magnetic field, it comes to rest with its length perpendicular to the directions of the field
wave length
wave crest
wave trough
wave amplitude
wave front
Correct answer is E
The wavefront of a time-varying field is the set of all points where the wave has the same phase of the sinusoid.
Which of the following statements is NOT true of the image in a plane mirror? The image is
the same size as the object
laterally inverted
virtual
magnified
the same distance behind the mirror as the object is in front
Correct answer is D

A pressure cooker saves both time and fuel in cooking because inside the cooker, the
boiling point of water is raised
pressure is constant
heat is completely trapped
temperature is evenly distributed
volume of steam varies
Correct answer is A
When atmospheric pressure increases, the boiling point becomes higher, and when atmospheric pressure decreases (as it does when elevation increases), the boiling point becomes lower.
The water at the bottom of a waterfall is slightly warmer than that at the top because part of the
potential energy raises the water temperature
water absorbs latent heat from the atmosphere
kinetic energy is changed into internal energy
dropping mass of water increases the heat capacity
