Answer:
apply a voltage to a cable a current is created that increases linearly with the voltage
Explanation:
apply a voltage to a cable a current is created that increases linearly with the voltage according to the ohm ratio
V = I R
Where R is the resistance of the wire
If the applied voltage is high, the amount of current is also high, which is why when there are many electrons displacing ce, the shock between them increases significantly, causing an increase in the temperature of the cable that is reflected in an increase in resistance, for which continue to comply with Ohm's law the current should be a little lower
Answer:
In which school you are???
Explanation:
The amplitude of a wave tells you how much energy it's carrying.
You might see light waves with large amplitudes if you're 10 miles from the sun, or if your little brother comes and points a flashlight right into your eye.
Answer:
i) 2
ii) No
Explanation:
i) The man will hear two sounds: one through the rail, and one in the air.
ii) The sounds will not reach the man at the same time. Sound travels faster through solids than through gases, so he will hear the sound through the rail before he hears the sound in the air.
