The instrument generally used for determining the radius of curvature of spherical surfaces is
A)
Screw gauge
B)
Vernier calliper
C)
Spherometer
D)
Micrometer screw
A spherometer is specifically designed to measure the radius of curvature of spherical surfaces, such as lenses and curved mirrors.

The compounds used for sterilisation which are harmful to living tissues are
A)
Antipyreties
B)
Disinfectants
C)
Analgesics
D)

Disinfectants are chemical compounds used for sterilisation of non-living surfaces and are harmful to living tissues. Antiseptics are the similar agents that can be safely used on living tissues. Antipyretics reduce fever, and analgesics relieve pain, so they are unrelated.
The material that can be used to convert solar energy into electricity is
A)
Mica
B)
Aluminium
C)
Silicon
D)
Silver
Solar cells use a semiconductor material to convert sunlight into electricity through the photovoltaic effect. Silicon is the standard semiconductor used in most solar panels. Mica is an insulator, aluminium is a conductor used mainly for support/wiring, and silver is used in contacts but not as the main converting material.
When a moving bus stops suddenly, the passengers are pushed forward because of the
A)
friction between the earth and the bus
B)
friction between the passengers and the earth
C)
inertia of the passengers
D)
inertia of the bus
When the bus stops suddenly, the passengers’ bodies tend to keep moving forward due to inertia of motion. Inertia is the property of a body to resist any change in its state of motion. The bus stops, but the passengers continue moving forward for a moment, so they are pushed forward relative to the bus. The other options are incorrect because friction is not the main cause here, and the bus’s inertia does not push the passengers forward.

Malfunctioning of which of the following organs causes jaundice?
A)
Stomach

The stomach, pancreas, and kidney are not the primary organs whose malfunction directly causes jaundice.
