BOOM’ S PROBLEM PS 4.3 – Torque (Rotational Equilibrium) Problems 1. A crane supports a 3.0 kN weight as shown. The crane’s boom is 8.0 m long and is at an angle of 30˚ from the horizontal. If the hydraulic support is attached to the boom 2.0 m from the bottom of the boom‚ then: a) what is the compressional force in the hydraulic? b) what is the magnitude and direction of the force on the pin at the bottom of the boom? a) ∑Torque = 0 F cos 30˚ x 2.0 = 3000 cos 30˚ x 8.0 F = 24

Explain how human activity can affect water availability and quality. (10) Agriculture plays a significant role in the quality of water and three factors come into play when considering agricultural effects: pesticides‚ fertilizers and the waste produced by farm animals. When pesticides or fertilizers are applied to crops the excess materials will either run off the land‚ or seep into the groundwater‚ with an eventual ending in bodies of water such as lakes‚ ponds‚ or streams.

Title: Rate of transpiration I found interesting to know how different environmental factors affect the rate of transpiration. There are different environmental factors‚ such as light intensity‚ humidity‚ wind and temperature that affect the rate of transpiration. Transpiration is a topic 9 in our Biology higher level book. I have read all the information through this chapter and researched some extra information. Based on this information that I had known I decided to take experiment of environmental

Analysis Graph 1 interprets the data shown on the table of results. The graph shows that the highest rate of reaction is at pH 7. This therefore supports my theory that at pH 7 the rate of reaction will be highest. This relate to other resources‚ such as books and the internet‚ which show that the optimum pH value for catalase is pH7‚ therefore there is no difference between the optimum pH and the pH used in the experiment‚ hence the enzyme structure is not affected by the pH and is most active
