We have the equation for electric field E = kQ/![d^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D)
Where k is a constant, Q is the charge of source and d is the distance from center.
In this case E is inversely proportional to ![d^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D)
So, ![\frac{E_{1} }{E_{2}} = \frac{d_{2}^{2}}{d_{1}^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7BE_%7B1%7D%20%7D%7BE_%7B2%7D%7D%20%3D%20%5Cfrac%7Bd_%7B2%7D%5E%7B2%7D%7D%7Bd_%7B1%7D%5E%7B2%7D%7D)
= 485 N/C
= 0.208 cm
= 0.620 cm
= ?
![\frac{485 }{E_{2}} = \frac{0.620^{2}}{0.208^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B485%20%7D%7BE_%7B2%7D%7D%20%3D%20%5Cfrac%7B0.620%5E%7B2%7D%7D%7B0.208%5E%7B2%7D%7D)
= ![\frac{485*0.208^{2}}{0.628^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B485%2A0.208%5E%7B2%7D%7D%7B0.628%5E%7B2%7D%7D)
= 53.20 N/C
The large leaves help it survive as they serve as the<u> organ for photosynthesis.</u>
Explanation:
- Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy.
- During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds
- Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food.
- Through pores, or stomata, leaves breathe in carbon dioxide and breathe out oxygen. Leaves also release excess water.
- Most leaves are broad and so have a large surface area allowing them to absorb more light
- A thin shape means a short distance for carbon dioxide to diffuse in and oxygen to diffuse out easily.
- The exchange of oxygen and carbon dioxide in the leaf occurs through pores called stomata.
- Normally stomata open when the light strikes the leaf in the morning and close during the night.
Answer: <em>4</em><em>2</em><em>.</em><em>3</em><em>2</em><em> </em><em>ms-1</em>
Explanation:
v = u+ at
v = 24.4 + ( 3.2×5.6)
v = 42.32 ms-1
