Explanation:

Answer:

B

Explanation:

Because , it is the answer .

Based on the information provided in the chart, the statement that is best supported is Atom X will donate electrons to Atom Y. Option A is the correct answer.

Atom X has 6 valence electrons, which means it has 6 electrons in its outermost energy level. Atom Y has 2 valence electrons, indicating that it has 2 electrons in its outermost energy level. In a chemical reaction, atoms tend to either donate or accept electrons to achieve a stable electron configuration. Option A is the correct answer.

Atom X has more valence electrons than Atom Y, suggesting that it is more likely to donate electrons. Since Atom Y has fewer valence electrons, it is more likely to accept electrons from Atom X. Therefore, based on the number of valence electrons, Atom X will donate electrons to Atom Y in order to achieve a stable electron configuration.

Newton's third law

Explanation:

A fish swimming uses its fins to push the water backward making it swim forward is obeying Newton's third law of motion.

Newton's third law of motion states that "action and reaction are equal and opposite".

When the fish uses its fin to push the water backward, it reacts by being propelled in the opposite direction which is in the forward sense.

The third law is clear indicator that forces are always in pairs. As the fish swims, a net force between the oppositely directed forces do not cancel out.

Answer:

D

Explanation:

Because speed is a scalar quantity which he has only magnitude and no direction while velocity is a vector quantity because it has both magnitude and direction.

Answer:

Check explanation section.

Explanation:

In order to understand balanced force and unbalanced forces the first law of Newton should be considered as a basic knowledge.

For Balanced forces, there is equal equality in the direction of the forces. In balanced forces, there is no acceleration.

For unbalanced forces, there is acceleration that is go say there is going to be movement. Therefore, net force is equal to unbalanced forces.

(i) Suitcase dropped from a height.

Answer: since there is movement that is acceleration, then the force here is unbalanced force. The resultant force is downwards.towards the greater force direction.

(ii) A bicycle moving with constant velocity on a straight road.

Answer: As the bicycle moves at constant velocity on the straight road the force here is Balanced. Frictional forces balances the forces from the cyclist.

(iii) The rope does not move in a tug of war on applying force at both ends.

Answer: Balanced force.

Answer:

The answer is 94 miles an hour.

Explanation:

Speed equals distance divided by the time taken to cover that distance. So to find the average speed of the train just divide the distance covered (846 miles) by the time taken by the train to cover that distance (9 hours) and that equals 846/9 equals 94 miles in one hour.

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question we have

Hope this helps you

Given:

Initial Volume [tex] \sf (V_1) [/tex] = 11.2 L

Initial Pressure [tex] \sf (P_1) [/tex] = 0.860 atm

Final Volume [tex] \sf (V_2) [/tex] = 15.0 L

To Find:

Final Pressure [tex] \sf (P_2) [/tex]

Concept/Theory:

[tex] \bf{ \underline{Boyle's \: Law} \: (Pressure - Volume \: Relationship)}[/tex]

"At constant temperature, the pressure of a fixed amount of gas varies inversely with the volume of the gas."

[tex] \bf{P \propto \dfrac{1}{V} \: (at \: constant \: T \: and \: n)}[/tex]

It can be also stated as "At constant temperature, the product of pressure and volume of fixed amount of a gas remains constant."

[tex] \bf{PV = Constant}[/tex]

If the initial pressure and volume of a fixed amount of gas at constant temperature are [tex] \sf (P_1) [/tex] & [tex] \sf (V_1) [/tex] and final pressure of the gas is [tex] \sf (P_2) [/tex] and volume occupied is [tex] \sf (V_2) [/tex], then according to Boyle's law;

[tex] \bf{P_1V_1 = P_2V_2 = Constant}[/tex]

OR

[tex] \bf{\dfrac{P_1}{P_2} = \dfrac{V_2}{V_1}}[/tex]

Answer:

By using Boyle's Law, we get:

[tex] \rm \longrightarrow \dfrac{0.860}{P_2} = \dfrac{15.0}{11.2} \\ \\ \rm \longrightarrow P_2 = \dfrac{11.2}{15.0} \times 0.860 \\ \\ \rm \longrightarrow P_2 = \dfrac{9.632}{15.0} \\ \\ \rm \longrightarrow P_2 = 0.642 \: atm[/tex]

[tex] \therefore [/tex] Final Pressure [tex] \sf (P_2) [/tex] = 0.642 atm
