Answer:
I think that cutting P.E. is not good. The class allows us to combat our growing obesity problem and it provides leisure time for students, something they sorely need. In Finland, schools have 15 minute breaks after every 45 minutes of teaching. This keeps the kids relaxed and happy. Sadness and stress are damaging to their health and their grades.
Explanation:
At a time when American children are increasingly absorbed in their screens and one-third are overweight, the need for robust physical education is acute. Last month, the federal government updated its recommendations for physical activity for the first time in 10 years. The guidelines now include recommendations for children as young as age 3, and advise a minimum of 60 minutes per day of moderate to vigorous activity for ages 6-17. Alas, only one in five teenagers meets this standard.
Inactivity has been called “the new smoking,” and the prevalence of obesity and inactivity may well mean children today will lead shorter lifespans than their parents. Children desperately need to learn the importance of physical fitness, how to achieve it, and how to maintain it. Well-taught physical education keeps students moving and motivated, building their competence and confidence so that they can stay fit over a lifetime.
Answer:
50 cm
Explanation:
Given that
Focal length of the mirror, f = 25 cm
Distance of the image, u = ?
Distance of the object, v = 50 cm
The formula for the focal length of a convex mirror is given by the relation
1/f = 1/u + 1/v,
where each of the parameters are exactly the same as what I've defined above. So now, if we plug in the values, we have
1/25 = 1/u + 1/50
1/u = 1/25 - 1/50
1/u = (2 - 1)/50
1/u = 1/50
u = 50 cm
So then, we can conclude that the size of the image is 50 cm
Your elbows should be glued to your ribcage as you lift/lower the weight. If you try to bring the bar to your chin, for example your shoulders will begin to move forward (shoulder flexion) and your exercise becomes a bicep-shoulder curl
