The answer is <span>It protects the seed until it matures.
Through the process of elimination:
- </span><span>It protects the seed until it matures. YES. A female pine cone the unfertilized seeds until they become mature. Then, the cone opens and seeds fall out of the cone.
</span><span>- It makes food for the adult plant. NO. The food of plants in made of green leaves that contain chlorophyll in the process of photosynthesis.
- It allows for photosynthesis to occur. NO. The cones have nothing to do with photosynthesis but they are responsible for reproduction.
- It acts as an object to attract birds. NO. The birds look for colourful flowers while cones are woody.
- It serves as an ornamental object on the tree. NO. Every part of plants has more important function than serving as an ornamental object.</span><span>

Answer:
Explanation:
The magnetic field is straight up. It is reducing . As per Lenz's law , direction of induced current is such that it opposes the reason which creates it . magnetic field in upper direction is reducing . So current will be such that magnetic field produced by it increases magnetic field in upper direction . In other words , induced current should create magnetic field in upward direction. It is possible when direction of induced current is anti - clockwise, when seen from above.

Answer:
F = 
.
Explanation:
Gravitational force between two objects of masses 
kept at a distance r is given by the formula
F =
Here ,
= 2m
= 
Thus , F = 
F = .

A positively charged particle is slowly moved away
from a strong, negatively charged plate Electric
The string of a bow and arrow is pulled tight. Elastic
Energy is defined as the ability to do work. There are two main forms of energy which are:
- Potential energy
- Kinetic energy
Chemical energy energy is a form of potential energy produced through chemical reactions. A car battery is an electrochemical that converts chemical energy into electrical energy for use in the iPod. The battery is made up of electrodes through which electron flows in one direction and current is generated by the potential difference set up
Gravitational energy is a form of potential energy that tends to pull all bodies to the center of the earth. It is an attractive force.
Electrical energy is a form of energy produced through the flow of electric current in a body. As the positive charge moves away from the strong negative plate, an electric current is produced.
Elastic energy is a potential energy stored in elastic bodies that can be stretched and are not plastic.
