Answer:
3m/s²
Explanation:
Force applied to an object can be calculated thus;
F = ma
Where;
F = force applied (Newtons)
m = mass of substance (kg)
a = acceleration (m/s²)
According to the information provided in this question, F = 12.0 newtons, m = 4.0 kg, a = ?
Derived from F = m.a
We have; a = F/m
a = 12/4
a = 3
The resultant acceleration of the object is 3m/s².
Answer:
Los elementos de la tabla periódica se distribuyen sobre la base de similitudes.
Explicación:
Los diferentes tipos de elementos se distribuyen en 8 grupos de tabla periódica en función de sus propiedades. Los elementos que tienen propiedades similares se colocan en el mismo grupo. Por ejemplo, el primer grupo de la tabla periódica son los metales alcalinos. Todos los metales alcalinos tienen algunas propiedades similares, es decir, un electrón en su capa más externa, alta reactividad y forma metálica, mientras que, por otro lado, los ocho elementos del grupo son gases nobles que tienen una capa más externa completa y no tienen reactividad.
We generally represent an element by its symbol. provided with the atomic number and mass number or atomic mass
Atomic number is the number of protons present in an element. It is constant for an element.
The mass number of element is the sum of number of protons and number of neutrons
The atomic mass is the total mass of all the protons and neutrons present in the element (in its nucleus).
the number of electrons is equal to number of protons in a neutral atom of element.
The mass of electrons is not included in the total atomic mass of element as it is very low.
So here
12 = it is the number of protons = atomic number of element.
The true statements are
The combined mass of protons and neutrons is 24.305
Answer:
The flash of green light may give off some type of energy that only emits from green light which probably energizes the Flubber
Explanation:
A flubber is a rubber like polymer that absorbs and amplifies energy. A flubber absorbs energy from a light source and electrons present in it are excited in order to emit light of higher wavelength. The green light absorbed by the flubber to emit longer wavelength of light emitting more energy.
