Inflate the balloon, measure the width of the balloon, heat the balloon using the heat lamp, and then measure the width again.
Answer:
From the outside human arms, bird wings, and bats wings look very different. Humans are covered in skin, birds are covered in feathers, and bats are covered in hair. But on the inside there are many similarities among human, bird, and bat forearms. Did you know that humans, birds, and bats have the exact same types of bones in their forearm? These organisms share the same forearm bones because they all evolved from a common ancestor.
Human, bird, and bat forearm bones include the humerus, ulna, radius, carpals, metacarpals, and phalanges.

Answer:
a = g (m₂ -m₁ sin θ) / (m₁ + m₂)
Explanation:
To solve this we must locate a reference system in the inclined plane, in this case the axis eg. it is parallel to the plane and the axis and is perpendicular to the plane, we take the direction to the right as positive.
Let's write Newton's second law for block 1 on the plane
X axis
T - Wₓ = m₁ a
Y Axis
N – = 0
We use trigonometry to find the components of the weight
sin θ = Wₓ / W
Wₓ = W sin θ
cos θ = W_{y} / W
W_{y}= W cos θ
We substitute
T - m₁ g sin θ = m₁ a
N = m₁ g cos θ
We write Newton's equations for block 2 that is hanging.
Note that if block 1 goes up, block 2 must go down, therefore for this block the positive direction is down.
W₂ - T = m₂ a
Let's write the system of equations
T - m₁ g sin θ = m₁ a
m₂ g - T = m₂ a
Let's add
m₂ g - m₁ g sin θ = (m₂ + m₁) a
a = g (m₂ -m₁ sin θ) / (m₁ + m₂)
Acceleration is the same for both blocks as they are connected by a rope
