ANSWERS TO MCQS

1.(a)

FOR YOUR INFORMATION:

– THE vitality density of lithium-ion cells utilized in right now’s cell phones and electrical automobiles is almost 4 instances that of older technology nickel-cadmium batteries. Assertion 2 is subsequently not appropriate.

– Lithium-ion batteries use aqueous electrolyte options, the place ions transfer between the anode (destructive electrode normally fabricated from graphite) and the cathode (constructive electrode fabricated from lithium), triggering the charging and discharging of electrons. Subsequently, assertion 1 is appropriate.

— Lithium-ion batteries are thought of environment friendly sufficient for telephones and laptops, however they nonetheless lack the vary that might make electrical automobiles a viable various to inner combustion engines.

— A serious drawback is that lithium metallic is extraordinarily reactive. The principle type of lithium corrosion are dendrites, that are branched lithium buildings that develop from the electrode and may probably move by way of the separator and attain the opposite finish, shorting out the cell. Subsequently, assertion 3 just isn’t appropriate.

Subsequently, choice (a) is the right reply.

2.(b)

FOR YOUR INFORMATION:

— Pink sanders is a unscented number of sandalwood that grows primarily in rocky and hilly areas. Subsequently, assertion 1 just isn’t appropriate.

— The botanical identify for crimson sanders is Pterocarpus santalinus.

— In Andhra Pradesh, it’s restricted to a small space of ​​about 5,200 sq. kilometers within the Palakonda and Seshachalam hills of the districts of Kadapa and Chittoor, in addition to some adjoining areas of Anantapur district, the Nallamalla forests in Kurnool and Prakasam, and sure areas of Nellore district.

— There are wild vegetations in some adjoining areas of Tamil Nadu and Karnataka.

— Pink Sanders is a protected species beneath the Conference on Worldwide Commerce in Endangered Species (CITES) of untamed fauna and flora. Subsequently, assertion 3 is appropriate.

— Pink Sanders is a quickly disappearing species restricted to a tiny geographic space. Slaughter is unlawful, export is closely restricted. Permission is required to fell and promote even timber on non-public farms. Assertion 2 is subsequently appropriate.

Subsequently, choice (b) is the right reply.

3.(c)

FOR YOUR INFORMATION:

— Cyclone Midhiliwhich crossed the coast of Bangladesh, weakened from a “deep despair” to a “despair”, in accordance with the Indian Meteorological Division (IMD).

— A deep despair (remnant of cyclonic storm ‘Midhili’) over Tripura and neighboring Bangladesh has weakened right into a despair and about 50 km east-southeast of Agartala and 160 km south- west of Silchar.

— It fashioned as a deep despair above the Bay of Bengal intensified into cyclonic storm ‘Midhili’

Subsequently, choice (c) is the right reply.

4.(b)

FOR YOUR INFORMATION:

– THE European Group for Nuclear Analysis (CERN), which hosts the Giant Hadron Collider (LHC) stated the group’s scientists have discovered the primary proof of the uncommon course of by which the Higgs boson decays right into a Z boson and a photon.

— The Giant Hadron Collider is a huge, advanced machine designed to check particles which might be the smallest identified constructing blocks of all issues. Subsequently, assertion 1 is appropriate.

— It has a 27 km lengthy monitor loop buried 100 meters underground on the Franco-Swiss border. In its operational state, it fires two proton beams at almost the velocity of sunshine in reverse instructions inside a hoop of superconducting electromagnets.

– THE magnetic subject created by the superconducting electromagnets holds the protons in a slim beam and guides them as they journey by way of the beam tubes and finally collide. Subsequently, assertion 3 just isn’t appropriate.

— The LHC makes use of a liquid helium supply system to maintain its crucial parts at an ultra-cold temperature of minus 271.3 levels Celsius, which is colder than interstellar area. Assertion 2 is subsequently appropriate.

Subsequently, choice (b) is the right reply.

5.(b)

FOR YOUR INFORMATION:

– THE The Union energy ministry determined to extend its coal-fired energy technology capability in a evaluate assembly held lower than per week earlier than the beginning of COP28.with plans so as to add a minimum of 80 gigatons by 2031-32.

— India is now the third world producer of renewable vitality. Non-fossil gas sources, together with giant hydroelectric crops, now account for greater than 40% of put in electrical energy capability, up from about 25% in 2013. Photo voltaic and wind capability now account for greater than 30% of whole capability. Subsequently, assertion 1 just isn’t appropriate.

— India at the moment has 168.96 GW of whole renewable vitality capability (as of February 28, 2023), together with round 82 GW in varied phases of implementation and round 41 GW within the tender stage.

He understands – 64.38 GW of photo voltaic vitality51.79 GW of hydroelectric vitality, 42.02 GW of wind vitality and 10.77 GW of organic vitality. Assertion 2 is subsequently appropriate.

Subsequently, choice (b) is the right reply.
