What is the difference between forming a hypothesis and making a prediction based on the hypothesis?
Alexus [3.1K]

Answer:

While a hypothesis is a guess that is predominantly used in science, a prediction is a guess that is mostly accepted out of science. A hypothesis is otherwise known as a good or intelligent guess. ... Moreover, hypotheses are testable guesses about the things that you'd expect to take place in your research study.

An elevator of massmis initially at rest onthe first floor of a building. It moves upward,and passes the second and third floors
Varvara68 [4.7K]

To solve this problem it is necessary to apply the concepts of Work. Work is understood as the force applied to travel a determined distance, in this case the height. The force in turn can be expressed by Newton's second law as the ratio between mass and gravity, as well

W = mgh

Where,

m = mass

h = height

g = Gravitational constant

When it ascends to the second floor it has traveled the energy necessary to climb a height, under this logic, until the 4 floor has traveled 3 times the height h of each of the floors therefore

h = 3h

Replacing in our equation we have to

W = mgh\\W = mg(3h)\\W = 3mgh

The correct answer is 4.
