Explanation:
The force acting between two masses is given by :
........(1)
Where
G is the universal gravitational constant
are masses
d is the distance between two masses
It is clear from equation (1) that the gravitational attraction between the bodies always increases if the masses of bodies increases and when the separation between masses decreases.
So, the correct answer is "the masses increase, and the distance between the centers of mass decreases". This is because the force of gravitation is directly proportional to the masses and inversely proportional to the separation.

The color green is the the color of light in the visible spectrum which appears the brightest, but with proper illumination, the color green-yellow appears to be the brightest, with the human eye having the maximum sensitivity of 555nn
Answer:
Explanation:
From the question we are told that:
Speed of Motor 1 
Speed of Motor 2 
Therefore
Frequency of Motor 1 
Frequency of Motor 2 
Generally the equation for Time Elapsed is mathematically given by
Where
Therefore
Wave speed = frequency (in Hz) x wavelength (in m) so wave speed = 11 x 0.011 = 0.121 m/s
