Answer:
- Option D is the correct answer.
Explanation:
It is given that a 2 kg ball is traveling at a speed of 4 m/s, so we have to find its kinetic energy.
KE = 1/2 mv²
KE = 1/2 × 2×(4)²
KE = 1/2 × 2×16
KE = 16 J
<u>Some information about Kinetic Energy</u>.
Kinetic Energy is the energy an object has because of its motion. It is directly proportional to the velocity of the particle and its mass. Kinetic energy is given by,
- KE = ½mv²
- It occurs due to the motion of the particle.
- If a particle at rest position, then the kinetic energy will be zero because that particle won't be accelerating.
Bacteria
Explanation:
Nitrification fixation takes place by nitrogen-fixing bacteria like Azotobacter, Klebsiella, Bacillus etc which convert atmospheric nitrogen gas into fixed-nitrogen compounds like nitrates or ammonium ions for the plants to readily absorb.
The nitrogen fixing bacteria can be free-living like cyanobacteria or live with symbiotic relationship with plants and fungi.
The chemical conversion of di-nitrogen to ammonia takes place with the help of enzymes like nitrogenase in combination with leghahemoglobin, a protein through a reduction reaction.
The existence of brain areas like Wernicke's and Broca's areas support Noam Chomsky's beliefs about language development.
Noam Chomsky is well known for his work on linguistics, especially, the evolution of transformational grammar. He presumed that formal grammar was directly accountable for an individual's capacity to comprehend and interpret basic pronouncements.
The Wernicke's Area is the region of the brain critical to language development. It is situated in the temporal lobe on the left hemisphere of the brain. Its functions involve language comprehension, semantic or grammar processing, language identification as well as language interpretation.
The Broca's area helps create speech sounds, whereas, the Wernicke's area contributes to comprehension of language.
