The wavelength of an electromagnetic wave is given by
\lambda =  \frac{c}{f}
where c=3 \cdot 10^8 m/s is the speed of light and f=1.10 kHz = 1100 Hz is the frequency. Substituting the numbers, we find
\lambda =  \frac{3 \cdot 10^8 m/s}{1100 Hz}=2.72 \cdot 10^5 m=272 km
So, the wave in the problem has a wavelength of 272 km.

a thundercloud whose base is 500m above the ground. The potential difference between the base of the cloud and the m ground is 2
kolezko [41]

Answer:

1.6×10⁻⁶ N.

Explanation:

From the question,

F = (V/r)q......................... Equation 1

Where F = Electric force on the raindrop, V = Potential difference between the base of the cloud and the ground, r = distance between the base of the cloud and the ground, q = the charge on a rain drop.

Given: V = 200MV = 200×10⁶ V, r = 500 m, q = 4.0×10⁻¹² C.

Substitute these values into equation 1

F = [(200×10⁶ )/500]×4.0×10⁻¹²

F = 1.6×10⁻⁶ N.

A scientist hypothesizes that the temperature at which an alligator's egg is incubated will determine whether the alligator will
WINSTONCH [101]

Answer:

  • The independent variable its A, the temperature.

Explanation:

There are two variable in this (mental) experiment. The temperature and the gender of the alligator.

The temperature its the independent variable, its the one we can control using the incubator.

The gender of the alligator, its hypothesized, will be determined by the temperature, so, its the dependent variable in our hypothesis.

The incubator will be used in all the eggs of the experiment, so, its not a variable.

The male alligators its one of the possible outcomes of the experiment. Again, not a variable.
