The magnetic forces exerted by the magnet can act at a distance on other magnets or on objects containing certain metals. The magnetic fields showcase the presence of magnetic forces. The magnetic forces arise due to attraction and repulsion of the poles inside the material. Opposite poles attract each other while similar poles repel each other.
A) it is endothermic and heat is absorbed by the system.
1. The higher the sea surface temperature, the faster the warm, moist air rises into the atmosphere. This updraft creates a donut-shaped vortex that is rising in the middle and going downward on the sides.
2. The more moisture in the air (humidity), the stronger the vortex will become as the moisture rises through convective currents, cools, and falls through convective currents. This eventually causes rotation of the storm mass and you get a tropical cyclone. So, the high sea surface temperatures and humidity are actually the engines that form a hurricane and causes it to increase in strength.
<span>3. High-level horizontal winds can prevent a hurricane from forming. These are called shear winds and they literally blow the top of the cyclone off, preventing it from forming properly. The storm can still become a tropical depression or tropical storm, generating strong winds and rain. But, it never develops into a tropical cyclone.
</span><span>4. By those conditions alone, no. While those are favorable conditions at the surface, other factors need to be conducive as well, including favorable winds through the depth of the atmosphere, upper-level high pressure and a surface low to focus convection.

Answer:
phosphorus sulfide should be P2S3
Explanation:
Phosphorus can't exists as an atom itself, it needs to be like oxygen, so it must have 2 atoms covalently bonded to each others, making it P2. Sulfide itself is sulphur bonded in a 3 way exchange. Sulphate is the 2 way exchange, so S3 would be attached to phosphorus, making it P2S3
