Her acceleration would increase, if mass decreases than the acceleration would increase
Answer:
Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. It speeds through the vacuum of space at 186,400 miles (300,000 km) per second.

Hope this helps :))
To solve the problem it is necessary to apply the theory of sine waves. The wavelength λ of a sinusoidal waveform traveling at constant speed v is given by

Where,
v= velocity
f = frequency
Re-arrange to find v, we have

PART A ) Replacing with our values we have,


PART B) In the case of the period we know that it is defined as a function of frequency as,

That is to say that using the previously given values we have that the period in seconds is,

PART C) Finally the transverse wave velocity is given by,

Where,
T= Period
Linear mass density
Re-arrange to find 



Answer:
therefore, more kinetic energy! An object has the MOST kinetic energy when it's movement is the GREATEST.
