Q4. The number of valence electrons in a good conductor is generally
Answer : Option D
Explaination / Solution:
The electron theory states that all matter is composed of atoms and the atoms are composed of smaller particles called protons, electrons, and neutrons. The electrons orbit the nucleus which contains the protons and neutrons. It is the valence electrons that we are most concerned with in electricity. These are the electrons which are easiest to break loose from their parent atom. Normally, conductors have three or less valence electrons; insulators have five or more valence electrons; and semiconductors usually have four valence electrons.
Q5. Index Number reveals the state of
Answer : Option D
Explaination / Solution:
No Explaination.
Q6. Primary germ layers are
Answer : Option A
Explaination / Solution:
Development of fetus start from zygote divisions to form embryo. The embryo undergoes multiple divisions to form blastocysts that arrange into layers. The primary layers are ectoderm, mesoderm and endoderm.

Q10. A bus start from rest with an acceleration of 1 m/sec2. A man who is 48 meter behind the bus with a uniform velocity of 10 m/sec. then the minimum time after which the man will catch the bus is
Answer : Option A
Explaination / Solution:
Let the distance traveled by the bus when man catch the bus be S meter distance traveled by the man when he catch the bus S'=S+48 meter
Given :
Initial velocity of bus u=0
Initial velocity of man u'=10m/sec Acceleration of Bus=1 m/s2
Accelerationof Man=0
We will use formula for displacement
By substituting the values in above equation we get,
Displacement of Bus
Displacement of Man
By substituting the value of S from eq(1) in eq(2)we get
=> t = 8, 12
Taking minimum value t = 8 sec
