Answer: The correct answer is "analog signals".
Explanation:
Digital signal: This signal varies as 0 or 1. It is discrete signal.
Cathode rays: They are the streams of the negatively charged particles.
Diode signals: Diode is a semiconductor device. It changes the alternating signal to the direct signal.
Analog signals: In this signal, the signal is varying by continuously changing the direction voltage or current with time. It is a continuously varying signal.
In the given problem, electronic signals that are varying signals produced by continuously changing the voltage or current in a circuit are analog signals.
Therefore, the correct option is (d).
B. Energy as heat flows from a higher temperature to a lower temperature
C. The amount of het in a closed system is constant
D. Energy as heat flowing into an object is determined by the amount of work done on the object.
I know the answer is not C.
Answer:
water, cold and moist
Explanation:
I just did a test on it and got it wrong using land, cold and dry and got it right using this anwer
Answer: gravity
Explanation: Despite being the weakest force, gravity works across infinite distances, making it responsible for the formation of the universe's structure.
