Answer:
The final velocity of 18 kg ball is 
= 42.09 
Explanation:
Mass of first ball 
= 18 kg
Mass of second ball 
= 47 kg
Initial velocity of 18 kg ball 
= 76
Initial velocity of 47 kg ball = 0
Final velocity of 18 kg ball = ??
Final velocity of 18 kg ball is given by the formula
= 
Put all the values in above formula we get
= 2 × 18 × 
= 42.09
Thus, the final velocity of 18 kg ball is = 42.09

- The stripe provides a readability function for electronic devices.
Answer:
Femur
Explanation:
The bone to forensically analyze in order to create a height profile of the victims would the <u>femur</u>.
The approximate height of a human can best be estimated by measuring the length of the bone that runs from the hip to the knee, otherwise known as the femur.
<em>For the males, the length of the femur in centimeters is multiplied by 2.32 followed by the addition of 65.53 in order to arrive at the approximate height of the individual. For the females, on the other hand, the length of the femur in centimeters is multiplied by 2.47 followed by the addition of 54.1.</em>
<em>Ten games</em> will be played.
The first team can be any one of 5 . For each of those, the opponent can be any one of the other 4 .
Number of ways to pair them up = (5 x 4) = 20 ways .
<em>BUT</em> ... Whether the Reds play the Blues, or the Blues play the Reds, it's the SAME GAME. Each possible game shows up twice in the list of 20 ways. So there are really only 10 different pairs ==> <em>10 games</em> .
