    Undergrad Amplitude Modulation: Sine Wave Carrier of 750kHz, 4.0V, Modulated by 3kHz, 0.5V

    Hi everyone, plx help me on this! I've worked out frequency modulation but can't understand amplitude modulation ... A sinusoidal carrier wave has a frequency of 750kHz and an unmodulated amplitude of 4.0V. The carrier wave is to be amplitude-modulated by a sinusoidal signal of frequency...

    Undergrad Calculating Melting Time for 7.5g Ice Cube at 0°C

    An ice-cube has a mass of 7.50 g. The ice-cube is at 0 °C. Heat from the surroundings reaches the ice-cube at an average rate of 1.25 J / s. How long does it take for all of the ice to melt? (specific latent heat of fusion of ice = 333 J / g) A 35.5 s B 55.5 s C 2000 s D 3120 s
