<h2>Apartment Explosion Reported </h2>
The apartment’s explosion, reportedly caused by a gas leak, produced a violent release of gas and heat. The heat increased the temperature of the air in the room, which means an increase in the air's molecular kinetic energy.
When heat is provided then temperature increases and the molecules of substances move rapidly by increase of kinetic energy (K.E) temperature increases. It is understood that heat increases temperature.
Answer:
Bitter Magnet inside a superconducting magnet
Explanation:
Since there are no options available, generally, the electromagnet that is considered the strongest is the Bitter Magnet inside a superconducting magnet.
This electromagnet produces 45 Tesla units which is a result of bitter magnet producing 33.5 Tesla and the superconducting coil produces the additional 11.5 Tesla.
Hence, justifying that the greater the current in the coil the stronger the electromagnet.
When a gas is heated to become a plasma, the atoms (or the molecules) of the gas become ionised. In the ionisation, the atoms loose electrons from the exterior energy levels and thus heating to achieve a plasma will create free electrons and ionized atoms (or ionized molecules).
A plasma can not contain neutrons, because neutrons together with protons make the nuclei of the atoms. To free the neutrons from the atomn nuclei there would be necessary HUGE temperatures.
Also a plasma does not contain neutral elements (atoms) or (neutral) molecules, but Ionized atoms and/or molecules and free electrons.
Thus the good answer is d)
Answer:
The pair of terminals to produce an output voltage of 8V are K and M.
Explanation:
A transformer is an electronic device that can be used to increase or decrease an output voltage. It consists of secondary and primary coils, and operates on the principle of induction.
= 
where: 
is the voltage in the secondary coil, 
is the voltage in the primary coil, 
is the number of turns in the secondary coil and 
is the number of turns in the primary coil.
In the question, let us combine the number of turns in the secondary coil. So that,
= 15 + 5 = 20
= 
= 
= 8
= 8V
For the output voltage to be equal to 8V, the pair of terminals required are K and M.
Answer:
Exposure to the Atmosphere
Composition of Rock
Surface area of the rock
Climate
Time
Explanation:
Exposure to the Atmosphere - how much of the rock mass is exposed to the environment affects how quickly the rock will be weathered by that very environment
Composition of Rock - what kind of minerals the rock is made of, how easy it is for those minerals to disintegrate and how quickly the react with water and air.
Surface area of the rock - a rick that has a wider surface or smaller pieces is more exposed than one that is a lump. A larger surface area increases the rate of weathering
Climate - if a rock is an area where there are high temperatures or very low temperatures, the rate of weathering is likely to increase. A similar point can be made about a region that experiences a lot of rain.
Time - the longer the rock is exposed to harsh conditions, the more it will experience weathering
