Question 2.
A transmission system at a radio station consists of essentially the following devices:
1. An oscillator, which converts a direct current into a high-frequency alternating current.
2. A transmitting antenna, which sends out radio waves having the same frequency as the current supplied by the oscillator.
3. A microphone, which picks up the sound waves and converts them into a suitable electric current with the same pattern as the sound waves.
4. A modulator, which enables the waves produced by the antenna to “carry” the pattern of the sound waves picked up by the microphone.

i dont understand wat ur tryna say ma dude but whatever it is its.............PIZZA
Answer:
The work must be negative or positive depending on direction of motion of the object
Explanation:
This is because
W= force x distance
And = F x S cosစ
And this is positive when
Theta is less than π/2 and negative when theta is less than or equal to π/2
Should be 8.7 m/s. Just divide 200 by 23 and round from there.
The equation you would have to use for this would be :
Voltage = current * resistance
Voltage = 12 * 4
Voltage = 48
Answer : 48V
