Answer:
x ’= 1,735 m, measured from the far left
Explanation:
For the system to be in equilibrium, the law of rotational equilibrium must be fulfilled.
Let's fix a reference system located at the point of rotation and that the anticlockwise rotations have been positive
They tell us that we have a mass (m1) on the left side and another mass (M2) on the right side,
the mass that is at the left end x = 1.2 m measured from the pivot point, the mass of the right side is at a distance x and the weight of the body that is located at the geometric center of the bar
x_{cm} = 1.2 -1
x_ {cm} = 0.2 m
Σ τ = 0
w₁ 1.2 + mg 0.2 - W₂ x = 0
x =
x =
let's calculate
x = 2.9 1.2 + 4 0.2 / 8
x = 0.535 m
measured from the pivot point
measured from the far left is
x’= 1,2 + x
x'= 1.2 + 0.535
x ’= 1,735 m
Its either B. force or A. net force but I will go with force because forces can either push or pull I hope it help you.
Answer:
30 m
Explanation:
Potential energy = kinetic energy + rotational energy
PE = KE + RE
mgh = ½ mv² + ½ Iω²
For a disk, I = ½ mr². For rolling without slipping, ω = v/r.
mgh = ½ mv² + ½ (½ mr²) (v/r)²
mgh = ½ mv² + ¼ m v²
mgh = ¾ m v²
gh = ¾ v²
h = 3v² / (4g)
h = 3 (20 m/s)² / (4 × 10 m/s²)
h = 30 m
It is to some sea creatures. Like the ones with air filled areas like lungs and swim bladders
Answer:
the heat of the water will cause the empty bottle to expand so as the air of the bottle gets bigger the balloon will get bigger
