Which of the following phases changes at point B on the diagram shown below? A)deposition
B)freezing
C)melting
D)boiling

Answers

Answer 1

Answer:

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.

How do you find cumulative effect of two or more forces acting on an object

Answers

The cumulative effect, or the resultant, of two or more forces is obtained by resolving the forces. This is done by addition if the forces act in the same direction through the same point and by subtraction if the forces act in opposite direcitons through the same point. However, if the forces are placed at an angle to one another, they must be resolved into their consituent x and y (and z if necessary) components and then their resultant is calculated.

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

$F_(net) = √(F_1^2 + F_2^2 + 2F_1F_2cos\theta)$

here we know that

$\theta$ = 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

Stephen and andy are sitting next to each other on a bench. according to the law of universal gravitational there should be a gravitational force between them. why don't they feel this force?A.) Universal Gravitational only applies to objects that are far from earth's surface

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

Answers

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.

dayshawn is traveling at 12 m/s away from the school. dayshaun's mom is looking for him because he is late coming home so she left the house and is driving toward the school at 5 m/s. The school is 6492 m from dayshauns house. at what position will dayshawn meet his mom and how long after she left the house did she find dayshaun? draw a motion map and solve. show your work

Answers

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

$d = v_1*t + v_2*t$
