<span> 1.the atom has 7 neutrons and 8 protons....
because the positively charged particles are the protons ...and 8 is also the atomic number ...so number of neutrons can be calculated by subtracting </span>atomic number from the mass number...which gives us the neutrons 7 ...
Hope it helps !!!
Force of gravity = Mass x Gravitational force
Fg=mg
Fg = (5.7)(9.8)
Fg= 55.86 N
The answer to this question is C
Answer:
increases dramatically
Explanation:
due to resistance tends to prevent the motion of a body. When speed increases, the particles of air are set into motion and this energizes them. More air gains increased acceleration and they collide with a body. This initiates a resistance against the motion of such body. for instance, wind resistance increases rapidly as speed increases.
