How do the interactions between the two atoms change when the atoms get closer than the balanced point?
ValentinkaMS [17]

Answer:

The strong attraction of each shared electron to both nuclei stabilizes the system, and the potential energy decreases as the bond distance decreases. If the atoms continue to approach each other, the positive charges in the two nuclei begin to repel each other, and the potential energy increases.

Chapter 05, Problem 15 Multiple-Concept Example 7 and Concept Simulation 5.2 review the concepts that play a role in this proble
Llana [10]

Answer:

Explanation:

The question relates to motion on a circular path .

Let the radius of the circular path be R .

The centripetal force for circular motion is provided by frictional force

frictional force is equal to μmg , where μ is coefficient of friction and mg is weight

Equating cenrtipetal force and frictionl force in the case of car A

mv² / R = μmg

R = v² /μg

= 26.8 x 26.8 / .335 x 9.8

= 218.77 m

In case of moton of car B

mv² / R = μmg

v²  = μRg

= .683  x 218.77x 9.8

= 1464.35

v = 38.26 m /s .

Two footballs (A & B) are thrown with the same amount of force. Football A has a greater mass. Describe the acceleration for
Sauron [17]
Newton's second law gives the relationship between force applied to an object, its mass and its acceleration:
F=ma
where F is the force, m the mass and a the acceleration.

A force F is applied to football A, whose mass is m_A, and so the acceleration of this football will be given by (re-arranging the previous equation)
a_A =  \frac{F}{m_A}

Similarly, the acceleration of football B will be
a_B= \frac{F}{m_B}
where m_B is the mass of football B, and where the force F applied to the two footballs is the same.

Since football A has greater mass than football B, m_A \ \textgreater \  m_B, if we compare the two previous formula we see that the acceleration of football B is greater than the acceleration of football A:
a_B \ \textgreater \  a_A
Therefore, if the same force is applied to the two footballs, football B will accelerate more than football A.

Why is our (a person's) gravitational pull NOT as strong as the Earth's gravitational pull
Bezzdna [24]

Answer:With gravity, two things with mass will want to move toward each other. However, we humans don't feel our gravity pulling on another person because it's not very big, but we do all feel the pull of Earth's gravity all the time - we're not all floating in the air, because that would be happening without Earth's gravity!
