Apply Newton's second law to the bucket's vertical motion:
F = ma
F = net force, m = mass of the bucket, a = acceleration of the bucket
Let us choose upward force to be positive and downward force to be negative. The net force F is the difference of the tension in the rope lifting the bucket and the weight of the bucket, i.e.:
F = T - W
F = net force, T = tension, W = weight
The weight of the bucket is given by:
W = mg
W = weight, m = mass, g = gravitational acceleration
Make some substitutions:
F = T - mg
T - mg = ma
Isolate T:
T = ma + mg
T = m(a+g)
Given values:
m = 5kg, a = 3m/s², g = 9.81m/s²
Plug in and solve for T:
T = 5(3+9.81)
T = 64.05N
Answer:
(E) ε = 9.00 V, r = 1.01 Ω
Explanation:
As we know that power across the resistance is given as
now we will have
now we have
now we can use it as
similarly now 100 ohm resistance is replaced by another resistance of 200 ohm
so we will have
now we have
now we can use it as
now we have
now to find voltage of cell we will have
<u>Explanation of the properties of electron spin:</u>
Electron spin:
Electron spin is a quantum characteristic of electrons. It is a mode of angular momentum. The magnitude of this angular momentum is perpetual. If the electron spins clockwise on its axis, it is described as spin-up; counterclockwise is spin-down.
- Electron spin has representative s
- The electron spin quantum number has representative ms.
Electron pair:
Electron pair is also known as lewis pair. Lewis pair consists of two electrons that fill the same molecular orbital but have opposing spins. Gilbert N. Lewis introduced the electron pair idea in a 1916 article.
Answer:
1)50000J
2) At the start of the trip
3) At the end of the trip
4) The higher the height above the ground, the higher the potential energy
5) As speed increases, Kinetic Energy increase
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.
