Answer:
= 40 cm
Explanation:
given data
string length = 30 cm
solution
we take here equation of length that is
L = ...............1
so
total length will be here
so will be
= 40 cm
The remains of Mesosaurus- a crocodile-like reptilian tells United States that South America, Africa and Antarctica were once joined along which implies they were once an enormous continent. However, because of the idea called the geological phenomenon, this one massive continent began to break so making individual continents.
Hi there!
We know that:
Force due to gravity = Mgsinθ
Force due to friction = μMgcosθ
Let the positive direction be directed in the direction of the block's acceleration, which is downward.
Thus:
ΣF = Mgsinθ - μMgcosθ
Solving for acceleration requires diving all terms by the mass, so:
a = gsinθ - μgcosθ
Substitute in given values. (g = 9.8 m/s²)
a = 9.8sin(30) - 0.3(9.8)cos(30) = 2.354 m/s²
