Question 3797

The acceleration due to gravity at the equator:

Ais less than that at the poles

Bis greater than that at the poles

Cis equal to that at the poles

Ddoes not depend on the earth's centripetal acceleration

Show answer

A. is less than that at the polesExplanation not yet available.

Question 3796

The isotope used for the production of atomic energy is:

AU-235

BU-238

CU-234

DU-236

Show answer

A. U-235Explanation: Uranium-235 (U-235) is the isotope used for the production of atomic energy because it is fissionable. When bombarded with neutrons, U-235 undergoes nuclear fission, releasing a large amount of energy along with additional neutrons, which sustain the chain reaction in nuclear reactors and atomic bombs.

Question 3795

Curie point is the temperature at which:

Amatter becomes radioactive

Ba metal loses magnetic properties

Ca metal loses conductivity

Dtransmutation of metal occurs

Show answer

B. a metal loses magnetic propertiesExplanation: The Curie point (or Curie temperature) is the temperature above which a ferromagnetic material loses its magnetic properties and becomes paramagnetic. At this point, thermal energy overcomes the magnetic alignment of atoms. For example, the Curie temperature of iron is about 770°C.

Question 3794

Tetraethyl lead (TEL) is

Aa catalyst used in burning fossil fuel

Ban antioxidant

Ca reductant

Dan antiknock compound

Show answer

D. an antiknock compoundExplanation not yet available.

Question 3793

The art and science of map making is called:

Aremote sensing

Bcartography

Cphotogrammetry

Dmapping

Show answer

B. cartographyExplanation not yet available.

Question 3792

What changes will happen to a ball of ice and water kept at exactly zero degree Celsius?

AAll ice will melt

BAll water will become ice

CNo change will happen

DOnly some ice will melt

Show answer

C. No change will happenExplanation not yet available.

Question 3791

The bats can fly in the dark because:

Athey can see the objects in darkness

Bthey have weak legs and are likely to be attacked by predators

Cthey generate flashes of light

Dthey generate ultrasonic sound waves

Show answer

D. they generate ultrasonic sound wavesExplanation not yet available.

Question 3790

Heat transfer horizontally within the atmosphere is called:

Aconduction

Bconvection

Cabsorption

Dadvection

Show answer

D. advectionExplanation not yet available.

Question 3789

Animals living in the tree trunks are known as:

Aarboreal

BVolant

CAmphibious

DAquatic

Show answer

A. arborealExplanation: Animals that live in or on trees are called arboreal animals. They are adapted to climbing and moving about among branches. Examples include monkeys, squirrels, chameleons, and tree frogs. Their adaptations may include grasping limbs, prehensile tails, claws, or adhesive pads that help them cling to tree surfaces and move efficiently among branches.

Question 3788

In which of the following processes energy is released ?

Arespiration

Bphotosynthesis

Cingestion

Dabsorption

Show answer

A. respirationExplanation: Respiration is a biochemical process in which food molecules (mainly glucose) are oxidized to release energy in the form of ATP (adenosine triphosphate). This energy is then used for various life processes such as movement, growth, repair, and maintenance. Respiration occurs in all living cells and takes place mainly inside the mitochondria. Chemical Equation: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy (ATP) In contrast, photosynthesis stores energy in glucose molecules, while respiration releases that stored energy for cellular use.
