## A-Level Physics: True or False statements

With reference to the figure above, a mass m hangs at the end of a rope which is attached to a support fixed on a trolley moving to the right with a speed v on a horizontal track. The angle, θ, is the angle the rope makes with the vertical. Are the following...

## A-Level Chemistry: Performing Chemical Calculations

A mass of 0.457 g of solid carbon dioxide was vapourised into an evacuated gas syringe at r.t.p. A small amount of inert gas was introduced into the gas syringe and the volume of the gas syringe was 334.5 cm³. The temperature was kept constant throughout. How much...

## A-Level Mathematics: Describing sequence of transformation & sketching graphs

The graph of y = f(x) is shown above. (a) The graph of y = f(2 – x) is obtained when the graph of y = f(x) undergoes a sequence of transformation. Describe the sequence of transformations. (b) Sketch the graph of y = f’(x), stating the equations of any asymptotes and...
