Myopia is the defect of human eye in which a person is not able to see the far off objects clearly but can see the nearby objects clearly.
It is due to the increase in focal length of the eye lens and the contraction in the size of eye ball.
It is cured by using the concave lens of suitable focal length.
Answer: i would chose a experiment that i have well researched and know how to do but nothing to common either such as the baking soda and vinegar experiment. A good one is Gummy Bear Osmosis, when i did that one came in first place. But there are several others as well.
Answer:
625000 N/ m
Explanation:
m= 20 kg
v= 30 m/s
x= 12 cm
k = ?
Here when the mass when hits at spring its speed is
Vi= 30 m/s
Finally it comes to rest after compressing for 12 cm
i-e Vf = 0 m/s
Distance= S= 12 cm = 0.12 m
using
2aS= Vf2 - Vi2
==> 2a ×0.12 = o- 30 × 30
==> a = 900 ÷ 0.24 = 3750 m/sec2
Now we know;
F = ma
F= -Kx
==> ma= -kx
==> 20 × 3750 = -K × 0.12
==> k = 625000 N/ m
I believe the answer is D. much smaller because most are only a little bigger than Jupiter.
