Increasing distance between the objects factor will cause the gravitational force between two objects to decrease. Therefore, option B is correct.
What causes gravitational force to decrease?
The gravitational force grows in proportion to the size of the masses . The gravitational force weakens rapidly as the distance between masses grows. Unless at least one of the objects has a lot of mass, detecting gravitational force is extremely difficult.
Gravity is affected by object size and distance between objects. Mass is a unit of measurement for the amount of matter in an object.
The force of gravity is proportional to the masses of the two objects and inversely proportional to the square of the distance between them. This means that the force of gravity increases with mass but decreases as the distance between objects increases.
Thus, option B is correct.

Answer:
B. 58°C
Explanation:
Hello,
In this case, the relationship among heat, mass, specific heat and temperature for water is mathematically by:
In such a way, solving for the final temperature we obtain:
Therefore, we final temperature is computed as follows, considering that the involved heat is negative as it is lost for water:
Thereby, answer is B. 58°C.
Regards.
Final answer:
The final temperature of the water is approximately 58°C (Option B) after it has lost 15 kJ of energy in the cooling process.
Explanation:
To calculate the final temperature of the water, we can use the formula of heat loss or gain, Q = mcΔT, where Q is the heat loss or gain, m is the mass, c is the specific heat, and ΔT is the change in temperature.
Setting the given values into our formula: -15,000 J = (135 g) * (4.184 J/g°C) * (T_final - 85°C).
Solving this equation for T_final gives us T_final ≈ 58°C. Hence, the suitable answer would be option B: 58°C.

Answer:
only chlorine can expand its octet.
Explanation:
An atom can expand its octet is it has empty d orbital
the electronic configuration of given elements will be:
B : 1s2 2s2 2p1 [Valence shell n =2 no d orbital]
O :1s2 2s2 2p4 [Valence shell n =2 no d orbital]
F : 1s2 2s2 2p5 [Valence shell n =2 no d orbital]
Cl :1s2 2s2 2p6 3s2 3p5 3d0 [Valence shell n =2 no d orbital]
Out of given elements only chlorine has empty d orbitals in its valence shell
Thus only chlorine can expand its octet.

3)HClO4=H+ +clo4—
C(H+)=0.023 M
pH=-log[H+]=1.63
POH=14-1.63=12.37
Final answer:
The pH and pOH for a solution are related through the equation pH + pOH = 14. The pOH for solutions with a pH of 2.23 is 11.77, and in a solution of perchloric acid with a concentration of .023M, the pH is 1.64 and pOH is 12.36.
Explanation:
The concept of pOH and pH are related through the equation pH + pOH = 14 at 25 °C. If you have the value of one, you can easily find the other. For your first two questions, the pH of solution is given as 2.23. Therefore, the pOH would be 14 - 2.23 = 11.77. Your answer to both questions 1 and 2 is B. pOH=11.77.
For question 3, the perchloric acid has a concentration of .023M. To find the pH, we calculate -log[H3O+], which gives about 1.64. Therefore, the pOH would be 14 - 1.64 = 12.36. Your answer to question 3 is B. pH=1.64 and pOH=12.36.
