Q. What happens to the magnetic field inside a solenoid when the current is increased? (2020)
A.
It decreases
B.
It remains constant
C.
It increases
D.
It becomes zero
Solution
The magnetic field inside a solenoid is directly proportional to the current. Therefore, if the current is increased, the magnetic field also increases.
Q. What happens to the magnetic field strength inside a long solenoid if the current is doubled? (2021)
A.
It remains the same
B.
It doubles
C.
It quadruples
D.
It halves
Solution
The magnetic field strength inside a solenoid is directly proportional to the current flowing through it. Therefore, doubling the current will double the magnetic field strength.
Q. What happens to the magnetic field strength inside a solenoid if the current through it is doubled? (2021)
A.
It remains the same
B.
It doubles
C.
It quadruples
D.
It halves
Solution
The magnetic field strength inside a solenoid is directly proportional to the current flowing through it. Therefore, if the current is doubled, the magnetic field strength also doubles.
A.
Rapid evolution of many species from a common ancestor
B.
Evolution of similar traits in unrelated species
C.
The extinction of a species
D.
The migration of species to new habitats
Solution
Adaptive radiation is the rapid evolution of many species from a common ancestor, often occurring when species colonize new environments with diverse ecological niches.
Correct Answer:
A
— Rapid evolution of many species from a common ancestor
Genetic drift refers to changes in allele frequencies in a population due to random sampling of organisms, which can lead to significant changes over time, especially in small populations.
Correct Answer:
A
— Change in allele frequencies due to chance
A.
Development of an embryo from an unfertilized egg
B.
A form of asexual reproduction
C.
A type of sexual reproduction
D.
Both a and b
Solution
Parthenogenesis is a form of asexual reproduction where an embryo develops from an unfertilized egg, and it is considered a type of asexual reproduction.
