Answer:
Change in velocity is -4m\s
acceleration is -2m\s^2 cause Change in velocity = final v - initial v
Explanation:
Calculating acceleration involves dividing velocity by time — or in terms of SI units, dividing the meter per second [m/s] by the second [s]. Thus the SI unit of acceleration is the meter per second squared .
Answer:
Explanation:
The objective here is to draw the Lewis structure for the polyatomic trisulfide anion and to be sure all resonance structures that satisfy the octet rule are included.
The Lewis structure for Polyatomic trisulfide anion
The first step is to the layout the skeleton of the Polyatomic trisulfide anion
S S S
However, the next step is to make sure we fill in the bonding pairs of electrons on the central atom.
Then , we move over to filling the lone pairs electrons before we finally have the Lewis structure for Polyatomic trisulfide anion as shown in the image below.
As Principle Quantum Number is 7, so the number of Azimuthal Quantum Numbers for this energy level is calculated by following formula,
l = n - 1
As, n=7
So,
l = 7 - 1
l = 6
So, n=7 contains 1, 2, 3, 4, 5 and 6 Sub-Shells.
Number of Electrons in Subshells,
Number of electrons in each subshell is calculated by following formula,
2 (2l + 1)
As, l=1 (given),
So, 2 (2(1) + 1)
2 (2 + 1)
2 (3)
6
Result:
The number of electrons in n=7 and l=1 are 6.
Answer: it is a good conductor of electriciy tht is what wires are made of and it is a good conductor of heat so it will be able to handle the heat from the electricity
