<span>C) It does not change. At the point where the phase of a substance changes, there is no temperature change but only the phase change. After this, the temperature then goes up or down depending on the type of phase change occurring. </span>
A would be the best answer beacuse
Ovaries - small, oval-shaped glands that are located on either side of the uterus. The ovaries produce eggs (ova - an ovum is one egg, ova means multiple eggs.) The ovaries also produce the main female sex hormones which are released into the bloodstream.
Answer: is<u><em> Second Law of Thermodynamics (conduction)</em></u>.
john stirs the hot soup with a spoon the heat travels up the spoon to his hand is due to the basic law of conduction, also known as the second law of thermodynamics . Heat always travels from hot things toward the cold things, is proved by the phenomena that a cup of tea always get cold, and and a cold dessert or ice cream always melts. Its not possible that the cup of tea become boiling by itself and similarly an ice cream getting frozen on its own in on a hot day. To understand this point there are three ways in which heat can travel namely, conduction, radiation and convection. The process due to heat travels up to the spoon from the soup towards john's hand is called conduction. Conduction is the process in which heat travels between two solid things that are at different temperature. Cooking soup in a saucepan with a metal spoon will make your fingers hot because of the conduction of heat, that travels through the boiling soup pan through metal spoon towards your hand.
Answer:
Steam-methane reforming
Electrolysis of water
Explanation:
Steam methane reforming involves reaction of methane with water in the presence of a catalyst such as nickel to form Carbon oxides and Hydrogen.
CH4 + H2O ⇌ CO + 3 H
Electrolysis of water involves splitting of water through application of electric current to give Hydrogen and Oxygen gas.
2 H2O(l) → 2 H2(g) + O2(g)
Since f=m(v^2/r),or fnet is equal to ma.
force = unknown
velocity=22m/s
radius=75m
f=m(v^2/r)
f=925(22^2/75)
f=5969.333N
