Answer:
B. convergent boundary
Explanation:
Convergent boundaries, where ocean plates are subducted at trenches, produce the most tsunamis because they produce the largest earthquakes
<span>The expected boiling point of a substance increases with an increasing molar mass of the substance. So I would expect the lighter compounds to boil at lower temperature. Also more polar molecules tend to boil at higher temperature.
Pentane is the lightest of all three compounds, so it should boil the soonest.
Heptane is a lot heavier than Pentane, but slightly lighter than Heptanol. So it should boil next.
Heptanol is the heaviest of all of the molecules and is also quite polar compared to heptane. So it should have the highest of all the boiling points.</span>
Answer:
Normalization is a systematic approach of decomposing tables to eliminate data redundancy. It is a multi-step process that puts data into tabular form, removing duplicated data from the relation tables.
Explanation:
NATURAL MAGNETS
A natural magnet is one that occurs naturally in nature. All natural magnet are permanent magnets , meaning they never lose their magnetic power.
Natural magnet can be found in Sandy deposits in various part of the earth .
The strongest natural magnetic material is LODESTONE also called magnetite.
ARTIFICIAL MAGNETS
These are magnets made by people.
It's these magnets that is in our refrigerator doors, which have extra-stronge magnetic power. There are two types of of artificial magnets. Temporary and Permanent Magnets.
Examples of artificial magnets are; electromagnet and the paper clip.
Examples of Permanent Magnets are; Alnico
Answer:
(e) resistance
Explanation:
Resistance opposes the flow of current ,current and charge are related to each other as Q=current×time so charge is dependent on the current
So if the resistance opposes the flow of current then it also opposes the flow of the charge
Resistance is independent on the frequency impedance and reactance also opposes the flow of charge but they are frequency dependent and resistivity is the property of the material
So option (e} will be correct option
