Determine the weight and volume of the cylinder (for lab experiment written on side). 2. For the mixed aggregates ensure they are well mixed. Now fill the cylinder with the aggregate to 1/3 the height of the cylinder using the scoop. 3. Compact the aggregate with the tamping rod giving 25 strokes without

Purpose: To investigate the relationship between the speed of sound in air through the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher

scholarly works of Raymond P. Tripp‚ Jr. and Lillian Faderman. Both of these authors wrote interesting and articulate academic articles on the same poem by Dickinson‚ “My Life had stood – a Loaded Gun”. In his essay Spiritual Action in “ My Life had stood – a Loaded Gun” Tripp considers “My life had stood – a Loaded Gun” to be one of Dickinson’s most complex and inventive poems. He even goes so far as to proclaim that “the form behind the many profiles of ‘My Life’ is the poets spiritual awakening”

Makalah Biologi Percobaan Reaksi Hidrogen Peroksida dengan Katalase Penulis: Jancolin Yani Pendahuluan Seperti yang kita tahu bahwa hydrogen peroksida yang dihasilkan oleh sel-sel didalam tubuh kita akibat metabolism sel akan terpecah menjadi gas hydrogen dan oksigen dengan adanya keberadaan enzim katalase. Zat hydrogen peroksida sangat berbahaya bagi tubuh dalam kuantitas yang banyak oleh karena itu harus dipecah dan dikeluarkan. Sebagian besar zat hydrogen peroksida

Prediction I think that the speed of the cart 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

constant speed AC motor‚ while the HP stage is driven by a variable speed DC motor. This feature allows variation of the intermediate pressure. Each stage is provided with its own dynamometer. At compressor’s inlet there is an airbox with a sharp-edged orifice for flow measurement. An intercooler is provided between the two stages‚ and an intercooler between the second stage and the pressure vessel. Connected to the pressure vessel is an exhaust pipe with a throttling valve and a calibrated flow
