The sample response given in the question is right.
To find the answer, we need to know more about the distance and displacement.
<h3>How distance differ from displacement?</h3>
- Displacement is the shortest distance between the initial and final points of a body.
- It is the change in position with a fixed direction.
- Displacement is a vector quantity and can be positive, negative or zero values.
- Distance is the length of actual path of the body between initial and final positions.
- It's a scalar quantity and it can be positive or zero.
- The magnitude of displacement is less than or equal to the distance travelled.
Thus, we can conclude that the given sample response is right.

Isabella has a pool that has an area of 678.32 dam² while Taddeo has one of 865.42 m². Which pool has the largest surface area?
Solution :
We know, 1 dam² = 100 m².
So, area of Isabella pool in m² is :
A = 678.32 × 100 m² = 67832 m² .
Therefore, area of Isabella is greater that volume of Taddeo .
Answer:
The voltage is
Explanation:
Since the main source of is the sea water then
The equation for the reaction in sea water would be
that is the ion would form a molecule and then release an electron
For river water
I.e the molecule would gain an electron and forms an ion
Now acts as reactant for seawater reaction and product for river water
The voltage of the concentration cell at initial stage is
Now at the voltage for the cell with concentration difference between sea water and river water is mathematical denoted as
Where is the number of electron = 1
So substituting values we have
Removing the negative sign
Answer:
Options: 1, 2, 3 and 5 are correct
Explanation:
- As per the Aufbau priciple, electrons go into the subshell having the most minimal conceivable energy.
- By Hund's standard, the electron arrangement of carbon, which is , in this manner the carbon particle contains two unpaired electrons.
- Electrons can never have parallel turn in s-orbitals. If there should be an occurrence of Helium, it has 2 electrons with parallel turn in its 1s orbital.
- The plan of the orbitals in a multi electron molecule is not quite the same as the course of action in a solitary electron particle inferable from the electron-electron shocks in a multi electron iota.
- In the Li particle, the 3s, 3p, and 3d orbitals have various energies.
- Helium has 2 electrons during the 1s orbital and none during the 2s.
