Plz help with physics homework its regarding a First-Class Levers Lab?

Question

1. Under what conditions can a first-class lever be used to magnify force? Give an example.

2.Under what conditions can a first-class lever be used to gain speed? Give an example.

3.Rocks used to be used to build the great pyramid of Egypt had to be moved great verticle distances. suggest how torque may have been used to accomplish the feat.

4. Name 5 activities in your life that do not involve torque.

5. Under what conditions is the mechanical advantage is greatest?

6.Should the clockwise torque be equal in magnitude and opposite in direction to the counterclockwise torque? Explain your answer.

7. What factors may have contributed to the differences between the clockwise torque and the counterclockwise torque?

Answer 1

try google, good luck!

Answer 2

you need to objective plant-growth experiments in manipulated environments that simulate in all probability effects of world warming--drought (decrease than-watering), flooding (severe over-watering), bigger temperatures, etc. unsure in case you have the tech and supplies to control the surely CO2 or no longer. in case you may get your arms on some shellfish eggs/larvae, you need to simulate diverse tiers of ocean acidification and notice how the larvae do.
