I think the correct answer from the choices listed above is option D. The element that behaves most like magnesium would be strontium. It behaves most like magnesium<span> because it is in the same family, the alkaline earth metals. Hope this answers the question.</span>

<u><em>Answer</em></u>

  • Sr

<u><em>Explanation</em></u>

  • In periodic table, the elements have almost same properties are present in the same group. As Mg and Sr are present in group II-A, so both behave most likely to each other due to having same valence shell electrons as well.
  • Si and Sn are present in group IV-A which have same behavior but different one from Mg due to different groups.
  • S is present in group VI-A which show different properties from all others one especially from Mg.

Research to find out 5 uses of magnets in our daily life in medical contexts, route finding, security, sorting steel from other
bearhunter [10]

Answer:

Medical: Magnets are used for the RMN, which uses waves and magnets to create images of the body, this process is really complex because is deeply related to quantum mechanics, so i will not dive in the topic.

Security: You can attach a magneto to a sensor, and when the magnet detects a metal, a current flows to the sensor and it can make a noise. This system is used to detect if someone has something of metal (like a knife for example) and a similar system is used to detect land mines or metals under the ground, which can be related to "route finding".

Sorting steel: When you have a mix of different metals, some of them will be attracted to the magnet and others not. An example where this is used is when you have a piece of steel with impurities, you can melt it and use a magnet to only grab the steel and leave most of the impurities.

Recycling. Big magnets are used to manage large pieces of steel that may be difficult or dangerous to handle by hand, for example. in order to move old cars and objects of similar size of steel, a big magnet is used.

Music: Modern instruments like electric guitars or electric basses, use magnets in the pickups: The magnet detects the movement of the strings, and this creates a current in a copper wire that is winded around the magnets, and that current then is transformed into sound by the amplifier.

A 28.5 gram piece of iron is added to a graduated cylinder containing 45.5 mL of water. The water in the cylinder rises to the 4
sweet-ann [11.9K]

Answer:

7.92 .g . mL^-1

Explanation:

Data provided in the question

Water liters = 45.5 mL

Pace of iron = 28.5 gram

Rise in the water in the cylinder = 49.1 mark

So by considering the above information

As we know that

Density = \frac{Mass}{Volume}

where,

Mass = 28.5 gram

Volume = 49.1 - 45.5

              = 3.6 mL

So, the density is

Density = \frac{28.5}{3.6}

= 7.92 .g . mL^-1

Basically we use the density formula by dividing the mass with the volume
