The answer is; C
Nuclear reactors are small and lightweight (ratio of size to power generated) and provide energy reliably compared to other sources. They can carry their own weight by many folds ration. This is why they are also muted as the ideal source of energy in space exploration.
A. Tree
B. Shapes
C. Grass
D. Mehndi
Answer:
F1 is equal to F2
Explanation:
Here
F1 is the gravitational force exerted by the earth on the satellite.
F2 is the gravitational force exerted by the satellite on the earth.
Now these two forces are equal but opposite in nature. This is given by the Third law of motion by Newton. According to this law, when there is force exerted between two objects, one force is balanced the other force which is equal in magnitude and opposite in nature.
Thus the gravitational force of the earth exerted on the satellite is equal to the force exerted by the satellite on the earth.
Hence F1 = F2.
