Health and safety presentation

Here is my presentation when uploaded into google docs the file dosnt come out as how i made it would you be able to give you my email so i can send the direct word file ?

My Summary

A loose electron within a conducter will travel randomly to loose spaces in other atoms valence shells untill a electromotive force is applied this will cause the electrons movement to be directed towards the positive pole causing current

What i Learnt

this week i learnt about the physics revolving around mass acceleration and force i also learnt formulas that use involving  change of temprture, gravity and the specific heat capacity of material . I learnt about the hazards associated with fires, there different ratings and how to counteract them

Finding an unkown angle

• Step 1 The two sides we know are Opposite (300) and Adjacent (400).
• Step 2 SOHCAHTOA tells us we must use Tangent.
• Step 3 Use your calculator to calculate Opposite/Adjacent = 300/400 = 0.75
• Step 4 Find the angle from your calculator using tan^-1

Tan x° = opposite/adjacent = 300/400 = 0.75

tan^-1 of 0.75 = 36.9

Solving unknown side

Start with:		sin 39° = d/30
Swap:		d/30 = sin 39°
Calculate sin 39°:		d/30 = 0.6293…
Multiply both sides by 30:		d = 0.6293… x 30 = 18.88 to 2 decimal places.

The depth the anchor ring lies beneath the hole is 18.88 m
