Answer:

C: Solutions W and Y have greater solubility than solutions X and Z.

Explanation:

Temperature and pressure affect the solubility of a solution as follows:

- the higher the pressure, the greater the solubility (because more pressure means more collisions between the molecules, so this improves the solubility)

- the higher the temperature, the greater the solubility (because higher temperature means higher kinetic energy of the molecules, so more collisions, and so this improves the solubility)

Therefore, considering these two factors, the solutions with greater solubility must be W (which has high pressure) and Y (which has high temperature).

Ok plz answer and tell me how to do it

Answer: 25N

method: total force in the right hand direction is 100N and total force in the left hand direction is 125N. To get the net force, we add forces if they are in the same direction and substract if they are in opposite directions. since 100N and 125N are in opposite directions, we substract the larger value from the smaller value. Then we get 25N in the left hand direction as the final answer.

In 3 meters a person running 0.5 m/s accelerates 1.2 m/s 2. How fast were they going afterward? Choose the right equation for th

Feliz [49]

Answer:

2.72 m/s

Explanation:

In 3 meters a person running 0.5 m/s accelerates 1.2 m/s².

It means,

Distance, s = 3 m

Initial velocity, u = 0.5 m/s

Acceleration, a = 1.2 m/s²
