Answer:
A new substance was formed
Explanation:
According to this question, a shiny and flexible metal called Magnesium (Mg) is burnt in air to produce a white powder that has no shiny or flexible properties, however, has more weight than the magnesium metal itself.
This is possible because a CHEMICAL CHANGE has occured, hence, a new substance has been formed. The formation of a new substance during the burning process (chemical reaction), induced the increase in mass.
An electric current has an associated magnetic field when the flow occurs in. This is also known as magnetic effect of current which has been<span> observed and quantified by </span>Ampere's Law<span>.
</span>Meanwhile, Current is produced in a conductor when it is moved through a magnetic field because the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move. This process of generating current in a conductor by placing the conductor in a changing magnetic field is called induction<span>.

Hence, when a electric wire is placed nearby another wire carrying current, due to magnetic effect of current in the wire carrying electric current, current is induced in the wire. Hence the electric pulse and it is known as induction.
Answer:
Cape Point lighthouse
Explanation:
The lighthouse is located South of Cape Town, at a point where boats turn to go around the tip of Africa.
The new lighthouse has the most powerful light of all the lighthouses in South Africa, with a power of 10 megacandelas. That's why it's being visible for up to 63 km around.
It's a very important lighthouse helping to conduct the traffic around dangerous waters where 2 oceans meet.
Measurements in physics is important because it enables people to argue using mathematics where numbers can be used to represent knowledge in a convenient manner when we show and communicate about a phenomenon.
Explanation:
When a physician is able to measure a phenomenon, then we get a foundation of understanding a lot of things in our universe.Measuring these things will help know how to use them in various applications.

The naturally occurring radioisotope which is used as the fuel for a nuclear reactor is the Uranium-235. It has been said that one kilogram of Uranium-235 can theoretically male about 20 terajoules of energy when used as a fuel for power plants.
