Answer:

Distance=\sqrt{\frac{Luminosity 4\pi }{App Brightness} }

Explanation:

The formula for apparent brightness is given by the next inequation:

B=\frac{L}{4\pi d^{2}  }

Where B equals apparent brightnes, L equals luminosity and D equals distance.

SO we just have to clear distance from the formula and are left with the inequation to calculate distance:

Distance=\sqrt{\frac{Luminosity 4\pi }{App Brightness} }

According to the spill-over effect , children who witness their parents engaging in frequent, aggressive conflict are more likel
Anna35 [415]

Answer:

parents who engage in dysfunctional conflict are also likely to have dysfunctional parenting styles

Explanation:

<u>Parents who raise children in a dysfunctional environment will most likely project their conflict into children.</u>

<u>Some common ways they will affect their children is:</u>

<u>Anxious behavior, which means that there will be a constant sense of nervousness and worry that will make them protective.</u>

<u>This can cause the kid at school will often be unable to relax, and parents will often remind him of the dangers or precautions to take while being absent from home.</u>

This can prevent a kid from relating to others, showing unjustified untrust.

On the other hand, other spillover effect can be hostile or angry behavior:

Since hostile parents will never be quite satisfied with their child's performance.

Parents will seek to gain compliance from their children.

<em>Since parents are the first-hand contact that a child has to know people, an aggressive tone of voice will make children have trouble interacting with more people.</em>
