• n

• 3n-k

• 2n

• 3n

What is the definition of Degrees of freedom of the system?

• 3n

• n

• k

• 3n-k

Which type of constraint can be expressed as a function of the space coordinates and time?

• Holonomic constraints

• Non-Holonomic constraints

• Generalized coordinates

• Degrees of freedom

What is an example of a Holonomic constraint?

• Length between any two points is constant

• Distance between the centre of the vessel and a fluid particle is r

• r ≤a

• 3n-k

Consider a fluid inside a spherical vessel of radius. If the distance between the centre of the vessel and a fluid particle is r, then we have r ≤a. What type of constraint is this?

• Degrees of freedom

• Generalized coordinates

• Holonomic constraints

• Non-Holonomic constraints
