Answer:
Explanation:
The law of gravitation has to be used in this question along with Newton's second law
To develop this problem it is necessary to apply the equations concerning the conservation of the moment.
By definition the moment can be expressed in two ways,
The first as a function of force and because of time, that is
And also based on mass and speed
Speed 1 is moving in the opposite direction to our reference system and it remains constant, as is the mass therefore
Equation both expression we have that,
Therefore the speed of the glider is 2m/s
Because gases flow easily. A hot batch of gas can rise through
the surrounding gas a lot easier than, say, a hot batch of mud can
rise through the surrounding mud.
Answer:
A. False, frequency can increase or decrease wavelength.
For example: a high frequency would mean there are shorter wavelengths that occur in a period. Meanwhile, a low frequency would indicate that the wavelengths are longer and in longer periods.
