Question

When a system changes from one to another
state the value of work done!
a) Depends on the force acting on the system
b) Depends on the nature of material
proesent in a
system
al Does not
depends on the path
d) Depends
the
on
Dath​

Answer 1

Answer:

a and d

Explanation:

BECAUSE WORK DEPENDS ON FORCE AND ANGLE OF DISPLACEMENT

Answer 2

a) Depends on the force acting on the system and c) al Does not  depend on the path are the correct statements.

What is work done?

• Whenever there is movement is a body in a certain direction by a particular force, then it is said that work is done.
• Work done is a scalar quantity.
• Work done is given in Joules.
• It is expressed as dot product of force applied on the system and the displacement of the body:
• Work done = F · d = F * d * cos θ, Where F is the force applied on system and d is the displacement of the body and θ is the angle between direction of applied force and direction of displacement of the body.
• Work done depends only on two factors: Force on body and direction of displacement of body.

Since, displacement is independent of the total path taken by the body, so the work done does not depend on the path of body. It only depends on the final and initial points of the body.
