of design will experience three phases of apparent weight: the lifting‚ falling and braking stages. At first‚ the rider will feel heavier as the carriage accelerates. Then‚ as the velocity is constant‚ the apparent weight will equal that of the real weight. Finally‚ as the ride slows at the top‚ the decreasing velocity will result in a lighter feel. During free fall‚ riders will feel weightless‚ before experiencing a dramatic increase in apparent weight during the braking stage. As the ride climbs

In its most general sense‚ the process of mixing is concerned with all combinations of phases of which the most frequently occurring ones are A 7. gases with gases. 2. gases into liquids: dispersion. 3. gases with granular solids: fluidization‚ pneumatic conveying‚ drying. 4. liquids into gases: spraying and atomization

Theory The first experiment focused on the concept of errors and uncertainties that are obtained during measurements. For an experiment to be successful‚ especially those that involve measurements‚ the number of significant figures must be known. Significant figures are the digits required to express a measured quantity and thus reflect the accuracy of the measurement. Uncertainty is defined as the smallest increment that can be measured and is defined by the instrument used. An error is defined

The Physics behind Flying Airplanes There are several aspects involved in the dynamics of airplane and how they become airborne. This report will address the main physics involved and mathematic formulae that prove how airplanes get above the ground from a small fighter jet to a massive Boeing 747. The necessities involved in keeping there massive weights in the air and the extreme forces needed to land these airplanes and bring them to a halt will also be explored. Firstly‚ the formula F

The two BASIC PRINCIPLES of smoke control were defined by JH KLOTE (Ref 2) as:a) Airflow can control smoke movement if the average VELOCITY is of sufficient magnitude. b) A PRESSURE difference across a barrier can act to control smoke movement.

Lab {4} Free Fall Motion Abstract Within this laboratory students used a Macintosh computer‚ scientificwork interface‚ and photogate to measure the acceleration of gravity‚ g‚ in a free-fall experiment. Using a “picket fence” dropped through a photo gate with disregard for air resistance; students calculated the results from the charted data and compared it with the accepted value of 9.8 m/s2 discussing any variations and their
