Divide 56 by 60 then x the answer by 6 then you get 5.6km which is your answer.
Answer:
8 electrons
Explanation:
Now you can figure out how many electrons, protons and neutrons Oxygen has: Atomic number (which is always the smaller of the two numbers) is 8. Hence 8 protons. Because the atom is neutral, there are also 8 electrons.
D. NaOH + HCI NaCl + H,0
Explanation:
The last option is a double displacement/replacement reaction.
This reaction is a neutralization reaction in which an acid combines with a base to produce salt and water only.
NaOH + HCl → NaCl + H₂O
- A double displacement reaction is one that occurs between ionic compounds.
- In this reaction, there is an actual exchange of reaction partners.
One of the following conditions serves as a driving force;
- Formation of water or any other non-ionizing compound
- Liberation of gases
- Formation of a precipitate

The wavelength of the radio waves is 3.04 cm.
<h3>Calculation:</h3>
λf = c
λ = c/f
where,
λ = wavelength
c = speed of light
f = frequency
Given,
f = 98.6 MHz = 98.6 × 10⁶
c = 3 × 10⁸
To find,
λ =?
Put the values in the formula,
λ = c/f
λ = 3 × 10⁸/98.6 × 10⁶
= 0.0304 × 10² m
= 3.04 cm
Therefore, the wavelength of the radio waves is 3.04 cm.

The distribution of the fossil fuel depends on the factors like land, temperature, altitude and so on. Because of the difference in all these factors in different areas, there is unequal distribution of fossil fuels.
<u>Explanation:</u>
The problem of allocation of resources arises due to the scarcity of resources, and refers to the question of which wants should be satisfied and which should be left unsatisfied. Because of the scarcity of resources in some areas, there is low production and therefore low growth in that area.
Most natural resources, including fossil fuels, are not distributed evenly around the Earth. Deposits of fossil fuels depend on the climate and organisms that lived in that region millions of years ago, and the geological processes that have since taken place.
