Answer:
3
Explanation:
v = v⁰ (its original speed) + a (negative acceleration) X t² (time)
v = 15 - 10 x 1.2 = 15 - 12 = 3 (it's slowing down)

Answer:
I. a, c, f and h
II. e
III. b, d, g and i
IV. i
Explanation:
I. Chemical symbols are simple abbreviations used to represent various elements or compound. They consist entire of alphabet.
For the diagram given above, the labelled parts which represent chemical symbol are: a, c, f and h
II. Coefficients are numbers written before the chemical symbol of elements or compound.
For the diagram given above, the labelled part which represent Coefficient is: e
III. Number of atoms of element present in a compound is simply obtained by taking note of the numbers written as subscript in the chemical formula of the compound.
For the diagram given above, the labelled part which represent the number of atoms of the element are: b, d, g and i
IV. When no number is written as subscript in the formula of the element in the compound, it means the element has just 1 atom in the compound.
For the diagram given above, the labelled part which indicates that only 1 atom of the element is present is: i
Answer:
Chemical energy
Explanation:
The energy held in the foods molecules a lunch pack is composed of is chemical energy.
They occur within food substances which originates from plants and animals as giant organic molecules.
- Since food is often derived from plants and animals.
- Plants produce their own food by producing macromolecules from simple inorganic substances in the environment.
- Animals takes up these food and build their own body through it.
- Plants and animal parts constitutes organic molecules in which chemical energy is duly stored.
- When the molecules are broken down, they released their chemical potential energy into heat energy.
