The best predictor of the radioactive nature of an isotope is the neutron-to-proton ratio of the atom. Isotopes are atoms of elements having the same number of protons however they don't have the same number of neutrons. Each isotope of an element will have different values of mass number.
Answer:
Momentum after = 2400 kgm/s
Explanation:
Momentum after = momentum before
Momentum after = m1v1 +m2v2
Momentum after = (600)(4) + (400)(0)
Momentum after = 2400 kgm/s
My average speed for a walk depends on how far I walk.
If I walk one mile or more, then my average speed is about 2 miles per hour.

Answer:
De un modo más claro, los sistemas energéticos son los modos que tiene el organismo para suministrar ATP a los músculos. Como decimos, en todos los esfuerzos físicos es necesario contar con la cantidad suficiente de energía y esto viene determinado por la producción de ATP, el adenosin trifosfato.
Answer:
The velocity is 
Explanation:
Given:
Force = 500N
Distance s= 0
To find :
Its velocity at s = 0.5 m
Solution:






Using the relation,



Now integrating on both sides
