"Exponential growth" means that the bigger it is, the faster it grows.
That's Choice 'D'.
Let us consider the centripetal force equation,
centripetal force F = mv² / r
f= force
v= velocity
m= mass
r= radius.
in all the factors only velocity has the power of 2. so when you double the velocity then it will become square of that.
if v= 2v , F = m4v² / r
so velocity is doubled it would produce the greatest change in the centripetal force.
Answer:
Pericardial sac has protective tole
Explanation:
Pericardial sac or pericardium is a fibrous tissue that surrounds the heart. It has two coats:
- the outter coat-parietal pericardium
- the inner coat-visceral pericardium or epicardium which is double-layered and contains pericardial fluid between those two layers (pericardial fluid is necessary as a lubricant for the heart movement).
Besides lubrication, percardium also protects heart from infections, fixes it and limits its movements.
Species is the correct answers!!!
