Answer:
ΔL=0.14m
Explanation:
The period of oscillations of simple pendulum is
Here L is length of pendulum and g is acceleration due to gravity
So the length of pendulum is:
So increase in length is:
ΔL=L₂-L₁
![=\frac{T_{2}^{2}g }{4 \pi^{2} }-\frac{T_{1}^{2}g }{4 \pi^{2} }\\=\frac{g}{4 \pi^{2} }[T_2^{2} -T_1^{2} ]\\ =\frac{9.8}{4 \pi^{2}}[(1.15+0.22)^{2}-(1.15)^{2} ] \\=0.14m](https://tex.z-dn.net/?f=%3D%5Cfrac%7BT_%7B2%7D%5E%7B2%7Dg%20%7D%7B4%20%5Cpi%5E%7B2%7D%20%7D-%5Cfrac%7BT_%7B1%7D%5E%7B2%7Dg%20%7D%7B4%20%5Cpi%5E%7B2%7D%20%7D%5C%5C%3D%5Cfrac%7Bg%7D%7B4%20%5Cpi%5E%7B2%7D%20%7D%5BT_2%5E%7B2%7D%20-T_1%5E%7B2%7D%20%5D%5C%5C%20%3D%5Cfrac%7B9.8%7D%7B4%20%5Cpi%5E%7B2%7D%7D%5B%281.15%2B0.22%29%5E%7B2%7D-%281.15%29%5E%7B2%7D%20%20%5D%20%5C%5C%3D0.14m)

It is B
When we look at a red apple, it's absorbing colors from the sunlight. It absorbs all the colors of the rainbow—except for red. The red light reflects off the apple and our brain and eyes work together to let us know what color we are seeing.
