The variables are as follows; 1. dependent variable- FTSE 100 Index (Y) 2. independent variable- UK government bond market (X1)‚ 3. independent variable- S&P 500 Index (X2) 4. Independent variable- US money exchange rate (X3). The main focus of this assignment would be to analyze and measure the impact on the FTSE 100 Index with other independent

force acting over the area A. Dimension: F/L2 Units of pressure are N/m2‚ which is called a pascal (Pa). Since the unit Pa is too small for pressures encountered in practice‚ kilopascal (1 kPa = 103 Pa) and megapascal (1 MPa = 106 Pa) are commonly used. Other units include bar‚ atm‚ kg/cm2‚ lbf /in2=psi. 9/4/2013 2 1 Absolute‚ gage‚ and vacuum pressures Actual pressure at a give point is called the ________________.
