Answer:
ase of convenience, since the beneficiary by having a burrow and the shrimp benefits from knowing that there are predators nearby.
Explanation:
This exercise asks to study the dependence between two animals, the shrimp and the puffer fish.
Two types of dependency are defined:
* Complete. What is when one animal lives off the other
* Convenience if one animal does not live on the other
In this case, both the shrimp and the predator do not live on each other, since they feed independently.
So it is a case of convenience, since the beneficiary by having a burrow and the shrimp benefits from knowing that there are predators nearby.
The correct answer is: the balloon benefits by getting a burrow to live in and the shrimp knows when predators are nearby.
Answer:
1 N
Explanation:
From coulomb's law,
The force of attraction between two charges is inversely proportional to the square of the distance between the charges.
From the question,
Assuming the charges are the same in both case,
F ∝ /r²....................... Equation 1
Fr² = k
F'r'² = Fr²........................... Equation 2
Where F' = First Force, r'² = First distance, F = second force, r² = second distance.
make F the subject of the equation,
F = F'r'²/r².................... Equation 3
Given: F' = 4 N, r' = 3 m, r = 6 m
Substitute into equation 3
F = 4(3²)/6²
F = 36/36
F = 1 N
Answer:
The energy that drives this movement is heat within the earth, this heat comes from two main sources which are;
1) residual heat left over from the formation of our planet billions of years ago.
2) The radioactive decay of naturally occurring chemical elements (notably uranium, thorium, and potassium ) in the earth releases energy in the form of heat. These two sources of heat warm Earth’s mantle and cause it to rise and sink, this rising and sinking creates a convectional movement of earth mantle.
