A missile is launched with a speed of 75 ms-1 at an angle of 30° above the surface of a warship. Find the horizontal range achieved by the missile. Ignore the effects of air resistance. [Take g = 10 ms-1]

Oscilloscope displays voltage against time. Horizontal axis is time, vertical axis is voltage. It shows waveform shape, amplitude, frequency, and DC offset.
Controls: timebase (time per division), Y-gain (volts per division), trigger (stabilizes display). DC shows baseline shift; AC blocks DC component.
Uses: measuring frequency (count cycles, use timebase), amplitude (count divisions, use Y-gain), comparing signals, troubleshooting electronic circuits.
