AQA A-level CHEMISTRY 7405/3 Paper 3 Question Paper & Mark scheme (Merged) June 2024 [VERIFIED When measuring the motion of an object, from where should we measure its position? - ANS-Always measure the position of an object from its centre of mass. For a spherical object, the position of the centre of mass can be measured accurately by measuring the diameter of the sphere and dividing by two. An equation is given and a student is asked to find the value of a constant term in the ...

A transmission line is operating with a voltage phase angle different of 30 degrees between the sending Vs and the receiving bus Vr. If the receiving end load is suddenly increased, the voltage phase angle difference will be? The phase angle will increase. When load is increased phase angle will increase. A load has a power factor of 0.9 lagging. If the load draws 100 MVA, what is the MW draw? 90 pf= mw/mva The high side of a delta-wye connection transformer is connected to a power s...
