A transmitter “encodes” or modulates messages by varying the amplitude or frequency of the wave – a bit like Morse code. At the other, a receiver tuned to the same wavelength picks up the signal and 'decodes' it back to the desired form
I think it’s A or D
Answer:
The percentage power lost in the transmission line if the voltage not stepped up is 50%.
Explanation:
Given that,
Current = 60 A
Voltage = 120 V
Resistance = 1.0 ohm
We need to calculate the power
Using formula of power
Where,I =current
V = voltage
Put the value into the formula
We need to calculate the percentage power lost in the transmission line
If the voltage is not stepped up
Then, the power loss
Put the value into the formula
The percentage power loss P''
Hence, The percentage power lost in the transmission line if the voltage not stepped up is 50%.
Answer:
Sleeping, since your brain is working, but your physical body is not moving at all or moving rarely, therefore there is no work done in the activity of sleeping.
