Explanation:
Answer:
option (B) decreases
Explanation:
According to the Wein's displacement law, the minimum wavelength of the radiated emission is inversely proportional to the absolute temperature of the body which emits radiation.
![\lambda_{m}\alpha \frac{1}{T}](https://tex.z-dn.net/?f=%5Clambda_%7Bm%7D%5Calpha%20%5Cfrac%7B1%7D%7BT%7D)
Where, T is the absolute temperature of the body and λm is the minimum wavelength of heat radiated.
Here, as the temperature increases, the wavelength decreases.
Answer:
<em>The correct option is D) fruit</em>
Explanation:
Both the gymnosperm and the angiosperms plants produce seed. Seeds are an essential part of reproduction in plants.
After fertilization has occurred, the ripened ovule is the part which turns into a seed. The size of the seeds depends on the type if plant.
After fertilization, the ovary forms the fruit. As the ovule is present in the ovule hence after fertilization, the seed which was made from the ovule gets enclosed in the fruit which was made from the ovary.
