Answer:
2.7%,Almost three percent of adolescents
Explanation:
The two most common eating disorders are anorexia nervosa and bulimia what percentage of American adolescents have experienced anorexia nervosa or bulimia
The National Institute of Mental Health reports that 2.7% of teens, ages 13-18 years old, struggle with an eating disorder.Almost three percent of adolescents ages 13-18 are diagnosed with an eating disorder. Generally, adolescent girls are at a higher risk for developing an eating disorder than are boys.Eating disorders are a daily struggle for females and males in the United States in which It is estimated that 1.0%
Four out of ten individuals have either personally experienced an eating disorder or know someone who has
You are correct because nothing is being done to the cake
Explanation:
Given that,
Mass of a freight car, 
Speed of a freight car, 
Mass of a scrap metal, 
(a) Let us assume that the final velocity of the loaded freight car is V. The momentum of the system will remain conserved as follows :

So, the final velocity of the loaded freight car is 0.182 m/s.
(b) Lost on kinetic energy = final kinetic energy - initial kinetic energy
![\Delta K=\dfrac{1}{2}[(m_1+m_2)V^2-m_1u_1^2)]\\\\=\dfrac{1}{2}\times [(30,000+110,000 )0.182^2-30000(0.85)^2]\\\\=-8518.82\ J](https://tex.z-dn.net/?f=%5CDelta%20K%3D%5Cdfrac%7B1%7D%7B2%7D%5B%28m_1%2Bm_2%29V%5E2-m_1u_1%5E2%29%5D%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20%5B%2830%2C000%2B110%2C000%20%290.182%5E2-30000%280.85%29%5E2%5D%5C%5C%5C%5C%3D-8518.82%5C%20J)
Lost in kinetic energy is 8518.82. Negative sign shows loss.
The metric unit to measure work which equals one newton meter is called One Joule.
