A 1.5V battery is connected to a small light bulb with a resistance of 3.5 what is the current in the bulb?

1 answer:

5 0

Technically, we don't have the information needed to calculate the current,
because you haven't mentioned the units of the 3.5 .

Since the 3.5 is a resistance, we strongly suspect ... and we'll therefore
assume ... that the 3.5 has the units of ohms. Then . . .

Current = (voltage) / (resistance) = (1.5/3.5) = <em>3/7 of an Ampere</em>.

(429 mA, rounded)

It would be adaptation because the finches live in different islands and each have different weather and resources

A train is traveling away from you at 120 km/h. it blows its whistle, and you hear a tone of 0.400 kHz. Take the speed of sound

Vaselesa [24]

Answer:B)439.21 Hz

Explanation:

Given

velocity of train $v=120 km/h\approx 120\times \frac{5}{18}=33.33 m/s$

frequency of train $f_a=0.400 kHz\approx 400 Hz$

speed of sound $c=340 m/s$

frequency from Doppler effect can be calculated by

$f_a=(\frac{c}{c+v})\cdot f$

$400=(\frac{340}{340+33.33})\cdot f$

$400=\frac{340}{373.33}\cdot f$

$f=400\times 1.098$

$f=439.21 Hz$

A cylindrical tube sustains standing waves at the following frequencies: 600 Hz, 800 Hz, and 1000 Hz. The tube does not sustain

Thepotemich [5.8K]

Answer:

Explanation:

In closed organ pipe notes with odd harmonics are produced and in open organ pipe notes with all odd and even harmonics are produced. notes with frequencies 600, 800 and 1000 Hz are produced. These are 3 , 4 and 5 times 200 Hz. ie both odd and even times of 200 . So fundamental frequency appears to be 200 Hz. There is no note available between 800 and 1000. It also indicates that 200 Hz is the fundamental frequency and the pipe is open at both ends.
