I don't know why the answer is D , because I can't see the list of choices.
The only way to get 8.0 Amps is by making a serious mistake.
The current in the second picture is 4.0 Amps.
If the resistors are identical, then the effective resistance of
two resistors in parallel is 1/2 the resistance of each one.
The resistance in the second picture is 1/2 the resistance
in the first picture.
Current = (voltage) / (resistance)
Cutting the resistance in half causes the current to double.
If the current was 2.0 Amps in the first picture, it's 4.0 Amps
in the second picture.
Answer:d
Explanation:
because the brighter the stars look the bigger they look
If the radius is 7.5 meters, then the circumference would be 47.1239. That times five is 235.6195
Answer:
Hz
Explanation:
We know that
1 cm = 0.01 m
= Length of the human ear canal = 2.5 cm = 0.025 m
= Speed of sound = 340 ms⁻¹
= First resonant frequency
The human ear canal behaves as a closed pipe and for a closed pipe, nth resonant frequency is given as
for first resonant frequency, we have n = 1
Inserting the values
Hz
