the answer is no. You need the two torques to equal in order to lift something. That is 9 X 2 = lifting torque and 9 X 3 = lifted torque.
As you can plainly see 18 < 27; so you cannot lift that 9 N weight located 3 meters from the fulcrum.
For an experiment performed in the laboratory to be effective, a controlled environment is essential.
A laboratory will help to increase the reliability of hypothesis testing, as there will be less interference from the external environment in the experiment.
The design of the laboratory must then be aligned with the needs of the experiment, providing materials and an environment necessary for carrying out the experiment and learning.
<h3 /><h3>What is a scientific experiment?</h3>
Corresponds to a scientific methodology used to test hypotheses on a topic, through the manipulation and control of variables to prove or disprove an assumption.
Therefore, a scientific experiment carried out in the laboratory will help to reduce bias and interference, generating greater reliability in the results found.
