Answer:True
Explanation: External factors are factors outside of an organisation or an institution that has the capacity of either adversely or positively affect the institution or the Organisation.
For an institution to prosper and perform optimally in an economy.or a country, such Institution must put into cognisance the possible external threats that are capable of affecting it, when Organisations or Institution put strategies in place to control or mitigate such externalities,the institution or Organisation will sure Prosper.

Answer:
3500j
0.250 kg
14.14 m/s
220500 j
93.91 m/s
Explanation:
K.E =1/2 m v^2
first question
1/2×700×10=3500 j
second question
2×78.2/25^2= 0.250 kg
Third question
8kj=8000j
root (2×8000/80)= 14.14 m/s
Last one
P.E=MGH
so it will be
P.E=50×450×9.8=220500 j
the speed
root (2×220500/50)=93.91 m/s
Proton: Its electrical charge is +1, its mass is 1, it's found in the nucleus
Neutron: Its electrical charge is 0, its mass is 1, it's found in the nucleus
Electron: Its electrical charge is -1, its mass is negligible, it's found outside the nucleus
Explanation:
Atoms consist of three types of particles:
- Proton: the proton is found in the nucleus of the atom, and it has a positive electric charge, equal to
(expressed in units of fundamental charge, it has a charge of +1). Its mass is 
, while its mass expressed in atomic mass units is 1 a.m.u - Neutron: the neutron is also found in the nucleus of the atom, and it has no electric charge. Its mass is similar to the mass of the proton (slightly larger), and neutrons and protons are held together in the nucleus by the presence of the strong nuclear force
- Electron: the electron orbits around the nucleus, far away from it. It has negative electric charge, opposite to that of the proton (
, or -1 in units of fundamental charge). Its mass is much lower than that of the proton, approximately 1800 times smaller, so it can be considered as negligible.
