The number of protons in an atom is the same as its atomic number, which is found on its corresponding atomic symbol in the periodic table of elements. And as long as this atom has a neutral charge, than the number of electrons will be the same. If the atom does have a charge, like say, 2-, then subtract 2 from the number of protons to get the number of electrons.
For the number of neutrons, you have to memorize the isotopes available sometimes. But usually something like carbon 14 will have a total of (in this case) 14 total protons/neutrons. So subtract this number by the number of protons(6), and you have 8 neutrons.

Answer:
Part a)
so here the angle made by the string is independent of the mass
Part b)
Explanation:
Part a)
Let the string makes some angle with the vertical so we have force equation given as
so we will have
so here the angle made by the string is independent of the mass
Part b)
Now from above equation if we know that angle made by the string is
so we will have
Answer:
Ultrasound has been used in a variety of clinical settings, including obstetrics and gynecology, cardiology and cancer detection. The main advantage of ultrasound is that certain structures can be observed without using radiation. Ultrasound can also be done much faster than X-rays or other radiographic techniques
