A jet stream forms high in the upper troposphere between two air masses of very different temperature. The greater the temperature difference between the air masses, the faster the wind blows in the jet stream.
.
.
So "Differences in temperature between two air masses" is the answer
Answer:
The value of g is
Explanation:
From the question we are told that
The mass of the weight is
The spring constant
The second harmonic frequency is
The number of oscillation is
The time taken is
Generally the frequency is mathematically represented as
At second harmonic frequency the length of the string vibrating is equal to the wavelength of the wave generated
Noe from the question the vibrating string is just half of the length of the main string so
Let assume the length of the main string is
So
The velocity of the vibrating string is mathematically represented as
Where T is the tension on the string which can be mathematically represented as
So
Then
=>
=>
=>
substituting values
Generally the period of oscillation is mathematically represented as
=>
The period can be mathematically evaluated as
substituting values
Therefore
so
substituting for L
=>
Answer:
The Moon is at the closest part of its orbit around Earth; the Sun and the Moon form a straight line with Earth.
Explanation:
The conclusion the captain could draw accurately is that;
The moon is probably at the closest part of its orbit moving round the earth. In addition, that the sun and the moon have formed a straight line with earth. This is due to the fact that high tides are higher and low tides are lower at a particular time each year.
