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.
Answer:
Explanation:
The volume of the tank = 50 kton
50 kton = 5 × 10⁷ kg
Since 18 grams of water will contain: 10 electrons × 6.023 × 10²³
Then;
5× 10⁷ kg will contain 
= 1.67 × 10³⁴ electrons
(b)
Suppose:

Then;
10⁻⁶ of 

Thus, the number of high energy neutrinos which will interact with water is:
= 
= 
= 
For 1.67 × 10³⁴ electrons, the detection rate is:


= 9.668 per day
Answer:
906.5 cm
Explanation:
1 m = 100 cm
9.065 m = 100 cm * 9.065 m = 906.5 cm
Let north as positive
Fnet=10n-5n
=5n north
