Answer: B) homogeneous mixture

Explanation:-

Homogeneous mixture are those mixtures in which dispersed phase is uniformly distributed throughout the dispersion medium. Thus there is no physical distinction between the dispersed phase and dispersion medium. Example: Sugar dissolved in water

Heterogeneous mixture are those mixtures in which dispersed phase is not uniformly distributed throughout the dispersion medium. Thus there is a physical distinction between the dispersed phase and dispersion medium. Example: sand dissolved in water.

In the given diagram, there is a uniform distribution of the dispersed phase and the dispersion medium and thus it is an example of homogeneous mixture.

The compound magnesium phosphate has the chemical formula Mg3(PO4)2. In this compound, phosphorous and oxygen act together as on

S_A_V [24]

The question is incomplete, the complete question is;

The compound magnesium phosphate has the chemical formula Mg3(PO4)2. In this compound, phosphorus and oxygen act together as one charged particle, which is connected to magnesium, the other charged particle. What does the 2 mean in the formula 5Mg3(PO4)2? A. There are two elements in magnesium phosphate. B. There are two molecules of magnesium phosphate. C. There are two magnesium ions in a molecule of magnesium phosphate. D. There are two phosphate ions in a molecule of magnesium phosphate.

Answer:

There are two phosphate ions in a molecule of magnesium phosphate.

Explanation:

The compound magnesium phosphate is an ionic compound. Ionic compounds always consists of two ions, a positive ion and a negative ion.

In this case, the positive ion is Mg^2+ while the negative ion is PO4^3-.

The subscript, 2 after the formula of the phosphate ion means that there are two phosphate ions in each formula unit of magnesium phosphate.

If an object is moving eastward and slowing down, then the direction of its acceleration vector is

iragen [17]

It would still be eastward because The direction of the velocity vector is always in the same direction as the direction which the object moves.

A 500N car is pulled up to 20m plant to a flat from 5m above the ground by an effort of 150N parallel to the plank what is the V

Stolb23 [73]

Answer:

Explanation:

VR = Velocity ratio = Distance moved by effort/Distance moved by load

Given:

Distance moved by effort = 20m

Distance moved by Load = 5m

VR = 20/5

VR = 4

Hence the velocity ratio of the car is 4

1. A train engine pulls the boxcars. What are the horizontal forces present?(1 point)

NikAS [45]

Force is the influence that is capable of bringing about motion

The correct options are;

1. C. The pull of the engine, friction force

2. A. Weight, push of the tracks against the wheel

3. D. The astronaut weighs the most on Earth and least on the Moon

4. Please see attached drawing for example

5. Please see attached drawing for example

6. The data points will fall along a line this that as the force increases, the acceleration increases

Reason:

1. The horizontal forces are the forces acting along the horizontal x-axis, therefore;

A train engine pulling a boxcar what horizontal forces are;

C. The pull of the engine, friction force

2. The vertical forces are the forces acting an the direction of the y-axis of a graph

The vertical forces present when a train pulls a boxcar are;

A. Weight, push of the tracks against the wheel

3. The weight of an astronaut, W = mass × Gravity

Therefore, the weight increases with increasing acceleration due to gravity

Therefore, the least weight is on the moon, where acceleration due to gravity is 1.6 m/s², and most on Earth where the acceleration due to gravity is approximately 9.81 m/s²

The correct option is D. The astronaut weighs the most on Earth and least on the Moon

4. The magnitude of the downward force is the sum of the vertical forces acting downwards

5. The net force is given by the vector sum of the forces

6. According to Newton's second law, Force, F = Mass, m × Acceleration, a

Therefore, where the students conduct the experiments rightly, we have that the data points will fall along a line this that as the force increases, the acceleration increases
