<span>The law of conservation of mass states that, "Mass can neither be created nor destroyed, only its form changes with respect to different forms of energy."
In any reaction, say 10 gms of water is decomposed into its constituents Hydrogen and Oxygen. But the mass remains conserved for the reaction. Although mass and energy are inter-convertible. But,the net mass/energy remains conserved i.e. the mass of products will be equal to the mass of reactants. </span>
The scale will read <u>112 grams.</u>
Why?
Since we already know the percent error of the scale (12%) and we also know the mass of the block that is placed on the scale, we can calculate what will be the read of the scale by using the following formula:
We can see that the scale will read 112 grams.
Let's verify that we are right by using the following formula to verify if the obtained value for the scale read will be 12%:
Hence, we can see that the scale will read <u>112 grams.</u>
Have a nice day!
Answer:
Electromagnetism studies the attraction of two bodies within a magnetic field.
Electromagnetic interaction is one of the four fundamental forces of the known universe. The charged particles interact electromagnetically through the exchange of photons. Experimentally it was concluded that the lines of force of magnetic fields were always closed, eliminating the possibility of a magnetic monopole, so that within a magnetic field there are two poles, in the solar system the attraction between earth and wind Solar is by means of a field.
The most correct theory on this topic is the Earth itself is protected from the solar wind by its magnetic field, most of those charged particles, and most of those charged particles are trapped in the Van Allen radiation belt.
Explanation:
The magnetosphere or magnetosphere is a region around a planet in which its magnetic field deflects most of the solar wind, forming a kind of protective shield against high energy charged particles from the Sun. This magnetic or magnetosphere atmosphere does not It is only in the solar system, but also usually occurs on other planets such as jupiter and others (since it occurs on all planets with a magnetic field)
Answer:
Chemical change :has change in mass, heat is needed, new element is formed, hard to reverse.......
Physicalchange:does not have change in mass, heat is not necessary, no new element is formed, easy to reverse
