Answer:

The warm seas create a large humid air mass. The warm air rises and forms a low pressure cell, known as a tropical depression.

Explanation:

Hurricanes arise in the tropical latitudes (between 10 degrees and 25 degrees N) in summer and autumn when sea surface temperature are 28 degrees C (82 degrees F) or higher.

Show all work: A rock contains 125g of a radioactive isotope with a half-life of 150,000 years and 875g of its daughter material

Xelga [282]

Answer:

$t = 500000\,years$

Explanation:

The time constant of the radioactive isotope is:

$\tau = \frac{150000\,years}{\ln 2}$

$\tau = 216404.256\,years$

The isotope decay is predicted by the following model:

$\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }$

$\frac{125\,g}{125\,g + 875\,g} = e^{-\frac{t}{216404.256\,years} }$

$0.125 = e^{-\frac{t}{216404.256} }$

The age of the rock is determined after algebraic handling:

$\ln 0.125 = -\frac{t}{216404.256}$

$t = 500000\,years$

Musicians can use beats to tune their instruments. One flute is properly tuned and plays the musical note A at exactly 440 Hz. A

kodGreya [7K]

Answer:

439 Hz

Explanation:

$f_1$ = Frequency of first wave = 440 Hz

F = Beat frequency = 1 Hz

$f_2$ = Frequency of the instrument

The beat frequency is the difference of the two waves which are interacting with each other

$F=f_1-f_2\\\Rightarrow 1=440-f_2\\\Rightarrow f_2=440-1\\\Rightarrow f_2=439\ Hz$

The frequency of the instrument is 439 Hz

Question 6 of 10

madreJ [45]

Answer:

The answer is "Choice B and Choice C".

Explanation:

In this question, the two features, which make electromagnetic waves effective for interaction, which they don't really need a method of travel of data and move information quite fast. The motion among magnetic and electrical forces is generated by electromagnetic radiation. These waves will spread without the need for a source for their movement, and they have high speed and also the electromagnetic waves it has the same frequency as light.
