Answer:

Explanation:

Rising temps, rising seas

The National Oceanic and Atmospheric Administration (NOAA) says average surface temperatures on Earth rose 1.71 degrees Fahrenheit (0.95 degrees Celsius) between 1880 and 2016, and that change is accelerating in recent years.Apr 23, 2018

Antarctica: High: 67.6 F (19.8 C)

Africa: High: 131 F (55 C)

South America: High: 120 F (48.9 C)

Australia: High: 123 F (50.7 C)

The pan flute is a musical instrument consisting of a number of closed-end tubes of different lengths. When the musician blows o
IgorLugansk [536]

Answer:

  f = 276.6 Hz

Explanation:

This musical instrument can be approximated to a tube system where each tube has one end open and the other closed.

In the closed part there is a node and in the open part a belly or antinode. Therefore the wavelength is

          L = λ/ 4

speed is related to wavelength and frequency

          v = λ f

          λ = v / f

we substitute

          L = v / 4f

          f = v / 4L

the speed of sound at 20ºC is

          v = 343 m / s

let's calculate

          f = \frac{343 }{4 \ 0.31}

          f = 276.6 Hz

Which change would decrease the total current, I, flowing through this circuit?
iren [92.7K]

Answer:

A. Increasing the voltage of the battery

Explanation:

The relationship between voltage, V, current, I and resistance, R, is given as follows;

V = I × R

∴ I = V/R

From the above relationship, the current flowing in the circuit is directly proportional to the voltage of the battery, and inversely proportional to the resistance, 'R', of the circuit

Therefore, increasing the voltage, 'V', of the battery, increases the total current, 'I', flowing in the circuit.
