Answer: the object should be overcome by buoyancy and rise in the fluid.
Explanation:
Explanation:
It is given that,
Electric field, 
We need to find the change in the electric potential energy of the proton-field system when the proton travels to x = 2.5 m
From the conservation of energy, the loss in potential energy is equal to the gain in kinetic energy and kinetic energy is is equal to the work done.




So, the change in electric potential energy of the proton field system is
. Hence, this is the required solution.
I had to look for the options and here is my answer:
Given that a guitar string has a basic frequency of 500hz, the frequency that can be set for this into resonant vibration would be 1500 Hz. The resonant vibration here is necessary in musical instruments because it delivers a vibrating system which leads to a higher amplitude at a particular frequency.
Answer:
yvutvuvutvtyvyvtvytvtyvtvytvytvy
That would be Earth, because astronomical unit is defined as distance between Earth and sun.
Hope this helps.
