In an atom there are neutrons, protons and electrons. the number of protons is the atomic number . the number of neutron is the atomic mass minus atomic number. the number of electrons is the number of protons.protons and neutrons are located in the middle of the atom. and in the first ring (the ring closest to the middle) it can hold 2 electrons if there is more than two it will go to the second ring (the second ring from the middle of the atom) in the second ring it can hold eight if there is more than eight it will go to the third ring from the middle and the forth ring from the middle can hold 12 atoms . the symbol for proton = +
the symbol for neutron = it has no symbols
the symbol of electron = - .
<h2>
It takes 0.867 seconds to get to the top of its motion</h2>
Explanation:
We have equation of motion v = u + at
Initial velocity, u = 8.5 m/s
Final velocity, v = 0 m/s - At maximum height
Time, t = ?
Acceleration , a = -9.81 m/s²
Substituting
v = u + at
0 = 8.5 + -9.81 x t
t = 0.867 s
It takes 0.867 seconds to get to the top of its motion
Answer:
W 1920 N
Explanation:
200kg at a location where g=9.6m/s^2
We have that the Force is mathematically given as
F=170.833N

Force </h3>
Question Parameters:
- The torque required to loosen a nut that is holding a flat tire in place on a car has a magnitude of 41 N · m,
- the end of a 24 cm-long wrench to <em>loosen </em>the nut
Generally the equation for the Force is mathematically given as
Therefore
F=41/0.24
F=170.833N
