Answer:
M = 500 J
Explanation:
Given that,
Mass, M = 1000 g = 1 kg
Height, h = 10 m
Potential energy is given by :
P = mgh
P = 1×10×10
P = 100 J
The kinetic energy at ground = 400 J
Mechanical energy = sum of kinetic and potential energy
So,
M = 100 + 400
M = 500 J
So, the mechanical energy of the system is 500 J.
Answer:
The correct option is;
Amplitude
Explanation:
When transmitting picture signals over the air by broadcasting stations, the signals are shifted into high frequency channels of Very High Frequency (VHF) or Ultra High Frequency (UHF) carrier currents and imposing the the television signal by changing the amplitude of the high frequency carrier current to match the transmitted television signal waveform shape
