Ram, Achin, Divya and Ritu were discussing about a grassland community. The community was made up of grass, antelopes and lions.
       
The children made the following remarks about the grassland community.
Ram : The source of all energy for all the populations in the grassland community, comes directly or indirectly from the Sun.
Achin : The grass population is much greater than the antelope population in order to support the energy needs of the antelope population.
Divya : There will be more lions than antelopes in the grassland community because energy is passed from the antelopes to the lions.
Ritu : Without the grass population, only the antelope population will be affected but not the lion population.
Which of the children made a correct remark?

A Ram only
B Ram, Achin and Divya only
C Ram and Achin only
D All of them

A Position and velocity as ball B
B Position and acceleration as ball B
C Velocity and acceleration as ball B
D Displacement and velocity as ball B


how?

Ans 1:

Class : Class 9
acceleration due to gravity should be negative for B while positive for A thus not same

Ans 2:

Class : Class 9
How position and acceleration will be same at that point?

Ans 3:

Class : Class 9
the displacement is same

Ans 4:

Class : Class 9
