water. Wear safety glasses. Procedure : Weight out about 1.5 g of sodium carbonate and place in a warm oven and leave to dry. (We do not do this – but WHY must you if you had time?) Accurately weight out 1.3g of sodium carbonate using the method of “weighing by difference”. Record the mass of Na2CO3 used to at least 2 decimal places. Weigh boat first‚ record value‚ then add Na2CO3‚ record value. The difference should be 1.3g. Operation Mass of weight boat + sodium carbonate Mass of weigh boat

While I was reading the story one question that kept running through my mind was in regard to the depth of information about the physical weights of the soldiers’ items. Why would O’Brien go into this much depth about how much every individual item weighs?

War is very stressful and can very easily become more then one can handle. I think

To alleviate this problem‚ many pilots have started attaching random lead weights to the back of the helmet. Find the appropriate weight that would best balance the head and minimize neck fatigue. Assumptions: (a) center of gravity (cg) of goggles is 8 inches in front of neck pivot point; (b) goggles weigh 2lbs.; (c) max. volitional neck torque is 480 in lbs.; (d) cg of lead weight is 5 inched behind neck pivot point‚ (e) bare helmet weighs 4 lbs

will decrease as more weight is added on top of the cart. This is because the more weight that is placed on the moving vehicle/object‚ the more downward force is produced. This would increase the friction between the wheels of the cart and the ramp’s surface. The increase in friction would slow down the moving object (cart). Apparatus Trolley/cart- this is essentially a wooden block with wheels and a rubber end‚ to provide the collision with a cushion upon impact. Weights- these were added to
