Q1. A tumor enclosed within a capsule is termed
Answer : Option B
Explaination / Solution:
A tumor enclosed within a capsule is called benign tumor. Benign tumors normally remain confined to their original location and do not spread to other parts of the body and cause little damage.
Q2. The Aufbau principle states : In the ground state of the atoms, the orbitals are filled in order of
Answer : Option D
Explaination / Solution:
The Aufbau Principle states that in the ground state of an atom, an electron enters the orbital with lowest energy first and subsequent electrons are fed in the order of increasing energies. The word 'aufbau' in German means 'building up'. Here, it refers to the filling up of orbitals with electrons.
Q3. Which of the following is a radioactive element
Answer : Option A
Explaination / Solution:
No Explaination.
Q4. A light bulb and an open coil inductor are connected to an ac source . If an iron rod is inserted into the interior of the inductor then
Answer : Option C
Explaination / Solution:
As the iron rod is inserted, the magnetic field inside the coil magnetizes the iron increasing the magnetic field inside it. Hence, the inductance of the coil increases. Consequently, the inductive reactance of the coil increases. As a result, a larger fraction of the applied ac voltage appears across the inductor, leaving less voltage across the bulb. Therefore, the glow of the light bulb decreases.
Q5. Blood vessels are found to be present in which region of eye?
Answer : Option D
Explaination / Solution:
The middle layer, choroid contains many blood vessels and looks bluish in colour.
Q6. The elasticity of supply measures
Answer : Option A
Explaination / Solution:
No Explaination.
Q7. if k is the thermal conductivity of the material of the bar of cross section A whose ends are maintained at temperatures and , the rate of flow of heat H is :
Answer : Option D
Explaination / Solution:
rate of flow of heat H depends on
hence
K = thermal conductivity of the material
Q8. Measure of the amount of organic material in the water, in terms of how much oxygen will be required to break it down biologically is termed as :
Answer : Option C
Explaination / Solution:
Measure of the amount of organic material in the water, in terms of how much oxygen will be required to break it down biologically is termed as Biochemical Oxygen Demand (BOD)
Q9. What is the shape of Fe(CO)5 molecule?
Answer : Option A
Explaination / Solution:
CN is 5.
Q10. If paired scores occupy the same positions within their own distributions (high with high and low with low)
Answer : Option B
Explaination / Solution:
If high scores on one variable are paired with high scores on other variable and low scores are paired with low scores, correlation will be high and therefore Pearson's r will be high and positive.
