Answer:
Zero
Explanation:
As we know that the force and the motion direction should always be perpendicular to each other due to which the work is done by static friction be zero
Therefore
F.dcos(theta) = F.d cos(90) = 0
Hence, the work done by static friction is zero
Therefore the same is to be considered
U didn’t ask a question so I’ll just say that’s cool that it moves like that
Work done = force × distance travelled in the direction of the force
Force= 2(9.81) = 19.62N
WD= 19.62×130= 2550.6Nm
just analyze it in this way:
20cos30*=10( radical 3 )
20sin30*=10
Answer:
The correct answer is - ask a question based on observation and then postulate a hypothesis.
Explanation:
The scientific method is the step by step process to find an answer to any scientific question with the help of scientific investigation or experiment. The steps that make an investigation successful are should be in the correct order. These steps are as follows:
*Make an Observation
*Ask a Question
*Do Background Research
*Form a Hypothesis
*Conduct an Experiment
*Analyze Results and Draw a Conclusion
*Report Your Results
