Answer:
light travels faster than sound
Step 1, ask a question
step 2, do research
step 3, make a hypothesis
step 4, test your hypothesis with an experiment
step 5, analyze your data
step 6, make a conclusion
Answer:
500 N
Explanation:
Given that,
The upward force is 800 N and the downward forces are 400 N, 500 N, 400 N.
At equilibrium, the upward forces will become equal to the downward forces. Let the reading in the right hand scale.
x + 800 = 400 + 500 + 400
x + 800 = 1300
x = 1300 - 800
= 500 N
So, the reading in the right hand scale is 500 N.
You can use a drill. I dont see why you would need much more.
Sir Isaac Newton laid the foundations for the creation of modern calculus through his work in the field of mathematics. His discovery of formulas that could be used to derive the areas of curved objects led to many of the mathematical breakthroughs of the last two centuries. He also helped in the field of science by discovering laws such as the universal gravitation law.
