Answer : Option C
Explaination / Solution:
No Explaination.
Q2. There are two types of measures of dispersion
Answer : Option C
Explaination / Solution:
Absolute measure of dispersion include range, quartile deviation, standard deviation, variance and relative measure of dispersion include coefficient of range, coefficient of quartile deviation, coefficient of standard deviation, coefficient of variance.
Q3. Kinetic theory relates measurable properties.
Answer : Option D
Explaination / Solution:
Kinetic theory explains the behaviour of gases based on the idea that the gas consists of rapidly moving atoms or molecules. It also relates measurable properties of gases such as viscosity, conduction and diffusion with molecular parameters, yielding estimates of molecular sizes and masses.
Q4. India invests only ____ % of its GDP on infrastructure which is far below that of China and Indonesia
Answer : Option A
Explaination / Solution:
Traditionally, the government has been solely responsible for developing the country’s infrastructure. But it was found that the government’s investment in infrastructure was inadequate.
Q5. The central problems of an economy are due to
Answer : Option B
Explaination / Solution:
Central economic problem asserts that an economy's finite resources are insufficient to satisfy all human wants and needs. It assumes that human wants are unlimited, but the means to satisfy human wants are scarce.
Q6. The total energy of an electron in the first excited state of the hydrogen atom is about −3.4 eV. What is the kinetic energy of the electron in this state?
Answer : Option B
Explaination / Solution:
Total energy of the electron, E = −3.4 eV
Kinetic energy of the electron is equal to the negative of the total energy.
K = −E = − (− 3.4) = +3.4 eV
Hence, the kinetic energy of the electron in the given state is +3.4 eV.
Q7. Select the mismatched pair out:
Answer : Option B
Explaination / Solution:
The term ecology, silent spring and ecosystem were coined by Haeckel, Carson and Tansley respectively. The term biome was not coined by Hutchinson.
Biome, as coined and applied by Clements, was not the ecosystem.
Q8. The ion which activates many enzymes involved in photosynthesis,respiration, nitrogen metabolism is
Answer : Option D
Explaination / Solution:
It is absorbed in the form of manganous ions (Mn2+). It activates many enzymes involved in photosynthesis, respiration and nitrogen metabolism.
Q9. Which of the following is not a part of colon?
Answer : Option A
Explaination / Solution:
The colon is divided into three parts – an ascending, a transverse and a descending part.
Q10. According to Cartesian sign convention the heights measured
Answer : Option D
Explaination / Solution:
No Explaination.
