At point B, the substance undergoes deposition, transitioning directly from a gas phase to a solid phase. The correct option is a.
At point B on the phase diagram, the phase transition occurring is deposition. Deposition is a physical process in which a substance transitions directly from a gas phase to a solid phase without passing through the liquid phase. This change is driven by a decrease in temperature or an increase in pressure.
During deposition, gas particles lose energy, causing them to slow down and come together to form a solid structure. This process is exemplified in nature when water vapor in the atmosphere turns directly into frost or ice crystals on a cold surface. Deposition is the opposite of sublimation, where a substance transitions from a solid to a gas without becoming a liquid.

Answer:
C. melting
option C is correct answer.
Answer:
Cumulative effect of two or more force can be found using Vector sum of all forces
Explanation:
Force is a vector quantity and in order to find the resultant of two or more forces we have to use the concept of vector addition
here we know that vector addition rule is given as
here we know that
= angle between two forces
so using this equation we can find the cumulative effect of two forces which are inclined at an angle with respect to each other
B.) The gravitational force is balanced out by the force of friction.
C.) The gravitational force between them is extremely small.
D.) The gravitational attraction is balanced by an equal and opposite gravitational repulsion
Answer:
C.) The gravitational force is balanced out by the force of friction.
Answer:
C. The gravitational force between them is extremely small.
Explanation:
The force of gravity is based off of the mass and distance of two objects. Stephen and Andy don't have large enough masses to feel an effect.
Forgive my drawing skills
Speed of Dayshawn travelling towards his home is 12 m/s
Speed of her mom towards his school is 5 m/s
They both starts at same time so whenever they will meet on their path the sum of the distance covered by Dayshawn and distance covered by his mom must be equal to the total distance of school and home
Now let say they both meet after "t" time when they starts motion
so we can write the total distance between school and home as
here d = 6492 m
= speed of dayshawn
= speed of his mom
now by solving the above equation
so they will meet after 381.9 s from start which will be 3.36 minutes from there start
Also at this time the distance covered by her mom will be
so they will meet at distance 1909.4 m from their home
