Lately I've seen how kids today have it easy compare to previous times. My niece, who recently turned 5, disrespects her parents (my sister and brother in law) to the extent that she will even hit her own mother. I'm actually 17 years old. I know that times have changed but I remember when I was a kid, if I even dared showed attitude, I would have gotten my rear up whipped. I've seen a trend on this particular subject. When I babysitter for my niece and her friends, they always act disrespectful to anybody of higher authority. In addition, why does society claim that its politically incorrect to spank your children. When I did sometime wrong around their age, I get spanked with a belt. That pretty much taught me to not commit those actions again.

What are your thoughts on this subject?

1) What is the frequency of high energy ultraviolet radiation with a wave length of 125 nm?

(1 nm = 1 x 10^-9 m)

2) You shoot a laser beam at the moon and see the reflected beam 2.56 seconds later. How far away is the moon?

3x-4y = -1

x+y=-5

Why are distance/velocity in the horizontal direction and independent of distance/velocity in the vertical direction?

Physics word problem! HELP!?

When the 10 km/hr bikes are 20 km apart, a bee begins flying from one wheel to the other at a steady speed of 30 km/hr. When it gets to the wheel it abruptly turns around and flies back to touch the first wheel, then turns around and keeps repeating the back-and-forth trip until the bikes meet, and squish!

How many kilometers did the bee travel in its total back-and forth trips?

Can you also show me the work? Thanks. :)

1. -5(-6 - x) = 6 + 3(8+2x)

2. -6(7 -x )=10(x+3) - 24

3. -3(-4x + 5) = 5(-3x + 7) + 10

Solve each queation or formula for the variale provide. Show work.

1. 3x - 4y = 7, for x

2. 15y + 1 = x, for y

3. ex - 2y = 3z, for x

4. 3/5y + a = b, for y

Can you show me the work? Thanks. :)

1. -18z - 5(2x-2) = -21x + 3

2. 7(2x + 6) - 4(2x - 3) = 13x + 19

3. 4+3(5x+14) = -39x - 8
