Answer:
no.
Explanation:
The reason this has
never happened is due to the source of magnetic fields: moving electric
charges. When electric charges (e.g. electrons) move in circles, they
produce a magnetic field. In a piece of iron, it is very easy to line up
these circles, getting all the little magnets to work together as one big
magnet.
For each of these circles, one side is the north pole and one side is the
south pole. Since each circle has two sides, each circle has a north and a
south pole. Even the smallest possible magnets (spinning electrons) have a
north and a south pole.
Answer:
B
Explanation:
The carriage has potential energy
Answer:
B: Increasing the volume inside the reaction chamber
Explanation:
It depends on the pH if the base. but normally light colors are for bases example blue green etc
Answer:
The answer is
<h2>4.54 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of rock = 454 g
volume = 100 cm³
The density of the rock is

We have the final answer as
<h3>4.54 g/cm³</h3>
Hope this helps you
