Answer:
Diana's speed relative to ground is <u>16 km/h</u> in the direction of motion of train.
Explanation:
Given:
Velocity of train in forward direction is,
Here,
Velocity of Diana relative to train in the backward direction is,
Negative sign implies backward motion or motion opposite to the direction of train's motion. Here, Diana is walking from front of train to back. So, Diana is moving in the opposite direction.
Now, we know that, for two bodies 'A' and 'B', velocity of 'A' relative to ground is given as:
Therefore, velocity of Diana relative to ground is given as:
So, Diana's speed relative to ground is 16 km/h in the direction of motion of train.
Freezing, as at the begginning they could slide past one another so the substance was a liquid and then it turned into a solid where the particles are even closer together and they have strong attractions between them

I don't understand your question ❓,the object.....of what experiment
The correct answer for the statement “All the scientific
theories used to explain the formation of the solar system are non-testable”. The
answers outdated, imaginative and unacceptable are wrong. These theories are
not proven and yet are not tested due to the complexity.
