The car's velocity after 5s : 10 m/s
<h3>Further explanation</h3>Given
velocity=v=72 km/h=20 m/s
time=t = 5 s
acceleration=a = -2 m/s²
Required
velocity after 5s
Solution
Straight motion changes with constant acceleration
vf=final velocity
vi = initial velocity
Input the value :
The car is decelerating (acceleration is negative) so that its speed decreases
The balanced chemical equation representing the process of photosynthesis is:
The reactants in the process of photosynthesis are and H
and the products of the reaction are glucose
and oxygen
. Oxygen is the nonpolar covalent gas which is released in the process of photosynthesis. The reactant
is a nonpolar covalent gas while the other reactant water
has polar covalent O-H bonds.
In the balanced chemical equation, the number of each type of element must be equal on both sides of the reaction.
Tetrahedral arrangement is resulted upon mixing one s and three p atomic orbitals, resulting in 4 hybridized orbitals →
hybridization.
In the context of valence bond theory, orbital hybridization (or hybridisation) refers to the idea of combining atomic orbitals to create new hybrid orbitals (with energies, forms, etc., distinct from the component atomic orbitals) suited for the pairing of electrons to form chemical bonds.
For instance, the valence-shell s orbital joins with three valence-shell p orbitals to generate four equivalent sp3 mixes that are arranged in a tetrahedral configuration around the carbon atom to connect to four distinct atoms.
Hybrid orbitals are symmetrically arranged in space and are helpful in the explanation of molecular geometry and atomic bonding characteristics. Usually, atomic orbitals with similar energies are combined to form hybrid orbitals.
