Momentum definition: the quantity of motion of a moving body, measured as a product of its mass and velocity.
Impulse definition: change of momentum of an object when the object is acted upon by a force for an interval of time
These are the definitions.
Hope this helps!

I'm not completely sure, but I believe the answer is B. Solid
Inertia is the name. Inertia is when a moving object stays in motion unless stopped by an outside force. This is Newton’s first law of motion
it forms a system because a system contains two or more organs or structures
Answer:
0.3 N
Explanation:
mass of cork = 0.01 kg, density of cork = 250 kg/m^3
density of water = 1000 kg/m^3, g = 10 m/s^2
Tension in the rope = Buoyant force acting on the cork - Weight of the cork
Buoyant force = volume of cork x density of water x g
= mass x density of water x g / density of cork
= 0.01 x 1000 x 10 / 250 = 0.4 N
Weight of cork = mass of cork x g = 0.01 x 10 = 0.1 N
Thus, the tension in the rope = 0.4 - 0.1 = 0.3 N
