Answer:
Hey Queen Messy here!
I believe it is true.
Weight is the way we usually describe what the scales tell us, but our weight is actually something different.
"When you get on the scale and it tells you that you weigh 50 kilograms, that isn't your weight. That's actually your mass", says Dr Nicole Bell from the University of Melbourne.
"In everyday speech weight and mass are used interchangeably, but weight is a figure arrived at by multiplying mass by gravitational acceleration".
Physicists use Newton's 2nd law (F = ma) to describe the forces acting upon an object moving through space, where force is equal to mass times acceleration.
"In the case of weight, we can describe the force as W = mg", says Bell. "That is weight is equal to mass times gravitational acceleration.
Weight is not measured in kilograms, but in Newtons.

Answer: Creative thinking
Explanation:
It should be noted that, Creative Thinking is the method by which a problem is solved with the help of thinking skills.
The thought that is present in mind is tries in the practical life so that the problem can be solved.
Going by the question asked, Mandleev was trying to arrange elements in a logical way. He thought of arranging the elements based on the atomic weight.
This gives a good oexample of creative thinking in which the thinking is applied and a logical result is product of the thinking.
