Intermolecular distance is the distance between the particles that make up matter. The graph below compares the intermolecular d

istances in two substances. One substance is gas and the other is a liquid. A bar graph is shown with the title Intermolecular Distance. The y axis title is Distance. The x axis title is Substance. There are two bars on the x axis. One is labeled X and the other is labeled Y. The bar for X is higher than the bar for Y. Which statement best describes the two substances?

Explanation:

In gases, the molecules are held together by weak Vander waal forces. Due to this they have more kinetic energy and hence, more number of collisions take place between the molecules of a gas.

Therefore, they tend to diffuse at a faster rate and distance traveled by them is more as compared to the distance traveled by the molecules of a liquid.

On the other hand in liquids, the molecules are held by more strong intermolecular forces of attraction as compared to gases but not strong enough as they are in solids. Due to this molecules of a liquid are able to slide past each other. Hence, they have medium kinetic energy.

Therefore, less number of collisions take place between molecules of a liquid as compared to gases.

Thus, we can conclude that particles collide in gas so, substance X is a gas.

X is the gas and Y is the liquid. Intermolecular distances are farther apart in gases than in liquids.

238,2U --&gt; 234Th +<br> 90
stiv31 [10]

Answer:

\\_{2}^{4} \alpha

Explanation:

In this question, we wish to find the missing nuclei for the equation:

\\_{92}^{238} U\rightarrow _{90}^{234} Th + _{Z}^{A} X

In order to find the missing species, we need to use the charge and mass balance law. That is, the mass should be conserved: the total mass on the left-hand side with respect to the arrow should be equal to the total mass on the right-hand side with respect to the arrow:

238 = 234 + A

Notice from here that:

A = 238 - 234 = 4

So far we know that the mass of X is 4. Similarly, we apply the law of charge conservation. The total charge should be conserved:

92=90+Z

From here:

Z = 92-90=2

We have a particle:

\\_{2}^{4} X

Looking at the periodic table, an atom with Z = 2 corresponds to helium. This can also be written as an alpha particle:

\\_{2}^{4} \alpha

HELP please, 50 points 5 minutes timed
shusha [124]

Answer:

Coordinate geometry is one of the most important and exciting ideas of mathematics. In particular it is central to the mathematics students meet at school. It provides a connection between algebra and geometry through graphs of lines and curves. This enables geometric problems to be solved algebraically and provides geometric insights into algebra.

The invention of calculus was an extremely important development in mathematics that enabled mathematicians and physicists to model the real world in ways that was previously impossible. It brought together nearly all of algebra and geometry using the coordinate plane. The invention of calculus depended on the development of coordinate geometry.

Answer:

13. c) Net

14. a) Gravity

15. d) Watt

16. b) the speed will suddenly decrease.

Explanation:

13. The <u>net </u> force is combination of all individual forces.

14. When we sit on the chair , then <u>gravitational force</u> acts on our body due to our mass.

F = mg

here, F = force due to gravity , g = acceleration due to gravity  and m= mass of the body

15.Power : It is the force acting per unit area .It is discovered by James Watt

Power =\frac{force}{area}

Power =\frac{N}{m^{2}}

Its unit is Nm^{-2} .In honor of the Scientist , its unit is Watt.

Watt = Nm^{-2}

16. When the parachute first opens , the <u>speed of the skydiver suddenly decreases</u> because of the resistance offered by the air particles.(For more details look at the figure attached)

17. Transfer of momentum from one object to other is t<u>he law of conservation of momentum</u><u> </u>(NOT ENERGY).So the answer is<u> </u><u>False</u>

<u> Law of Conservation of Momentum : </u> Total momentum of a system is conserved if no external force attack on it. Momentum can neither be created nor destroyed but transferred from one form to other.
