Speed is a scalar quantity that refers to “how fast an object is moving.”
Answer:
F = 51 10² N and The force applied is 11.6 times greater than the weight
Explanation:
As we are asked the force we can use Newton's second law and we calculate the acceleration by kinematics
y = v₀ t + ½ a t²
On the ground its initial velocity is zero (v₀ = 0)
y = ½ a t²
a = 2y / t²
a = 2 2.5 / 0.21²
a = 113.38 m / s²
We calculate the force
F = ma
F = 45 113.38
F = 5102 N
F = 51 10² N
For the relationship of this force with the weight, divide the two
F / W = 51 10²/45 9.8
F / W = 11.6
The force applied is 11.6 times greater than the weight
None of the energy is created nor destroyed
The fundamental quantum number, n, describes the energy of an electron and most likely separation from the nucleus.
<h3>Who or what is an electron?</h3>
A negative charges subatomic particle known as an electron can either be free or attached to an atom (not bound). One of the three main types of atoms within about an atom is an electron that is bonded to it; the other two were protons and neutrons.
<h3>What is an example of an electron?</h3>
The smallest elemental component of an atom, the electrons has a negative charge. In an atom, there are an equal amount of protons and electrons. One electrons and one protons are all that the hydrogen atom has.
