Answer:
I don't know!!!!I don't know!!!!I don't know!!!!Explanation:
Answer: Hypotheses, which are proposed explanations for scientific observations, help us properly design experiments because experiments are used to test those hypotheses. Experiments are designed based on the measurable variables defined in a given hypothesis.
Explanation: Make a list of all potential hypotheses to be tested. For each hypothesis, ask what would be true if the hypothesis were true. The experimental procedure is a step-by-step recipe for the science experiment. A good procedure contains enough detail that someone else could easily duplicate the experiment.
Hope this helps^^
Answer:
F₁ = F₂
Explanation:
Given that
floor pushing up on you by force F₁
gravity pulling down by force F₂
From second law of Newton's
F₁ - F₂ = m a
But here given that ,elevator is moving with constant speed .It means that acceleration of the elevator is zero.
a= 0 m/s²
F₁ - F₂ = m x 0
F₁ = F₂
Magnetic field lines come from North pole and goes to south pole, as there are two north poles, they will be going from both the poles.
In short, Your Answer would be Option 4
Hope this helps!
