Answer:
Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. In equation form, Newton's second law of motion is a=Fnetm a = F net m .

Answer:
estivation is my answer.
Explanation:
Hibernation and estivation are similar, but hibernation takes place during cold months.
Estivation during summer months, the amphibian becomes dormant during this time.
Answer:
a)r' = 4 r
b)
Explanation:
Given that car is moving with uniform speed.
At the verge of sliding
Friction force = Force due to circular motion
So we can say that
-----1
Where is the coefficient of friction
r is the radius of circular path
V is the velocity of car
a)
if the car speed become double
It means that new speed of car =2V
lets tale new radius of circular path is r'
---------2
From equation 12 and 2 we cay that
r' = 4 r
It means that we have to increase radius 4 times to avoid sliding
b)
In the above expression there is no any terms of mass ,it means that sliding speed does not depends on the weight of car.
So the sliding speed will remain same.
