Answer:
14 m/s
18 m/s
22 m/s
Explanation:
The car is moving at constant acceleration, so we can find its velocity at time t using the equation:
where
u = 10 m/s is the initial velocity
is the acceleration
t is the time
Substituting the different times, we find:
At t = 2 s:
At t = 4 s:
At t = 6 s:
Combustion is and example of an oxidation reaction to burning/high energy conversion.
<h2>Answer:</h2>
Low melting points and electrical conductivity in solids are not common properties of ionic solids.
<h3>Explanation:</h3>
In ionic compounds the electrons involved in the bonding are tightly packed under the influence of electrostatic force of attraction. So the movement of these electrons is very difficult.
In the melting point the bond breaking between the atoms is involved. Hence in case of ionic compound there is a high amount of energy needed to break the ionic bonds.
Electrical conductivity involves the free movement of electrons which is impossible in ionic solids.
So low melting points and electrical conductivity in solids are not common properties of ionic solids.
Metals in general, are good heat conductors

More specifically in the macromolecules of the cells.
These macromolecules could either be amino acids, proteins or nucleic acids. They
are responsible for the chemical changes and reactions that affects largely the
cell and its composition. Take for instance the cytoplasm of the cell where
these organelles are settled. These simple organelles are composed of
macromolecules which ignites and catalyses different functions that enables
cells, in macro-perspective in motion and metabolism. In intestines for
example, metabolism happens and breaking down parts of a food to simpler
compounds that are used and these nutrients delivered throughout the body and
again broken down by into smaller components.</span>
