Answer:
Aeroplane
Explanation:
they have tail surfaces to stabilize the wings
D, making observations. If you make observations, you obtain information through the senses.
The mass of the cylinder increased by a factor of 3, the gravitational potential energy increases by a factor of 3.
The given parameters:
- <em>Initial mass of the cylinder, m₁ = 1.0 kg</em>
- <em>Final mass of the cylinder, m₂ = 3.0 kg</em>
The gravitational potential energy of an object is calculated as follows;
P.E = mgh
where;
<em>m</em><em> is the mass </em>
<em>g</em><em> is acceleration due to gravity</em>
<em>h</em><em> is the height of the cylinder</em>
<em>when the </em><em>mass </em><em>= 1 kg</em>
P.E = 1 x g x h
P.E = gh
<em>when the </em><em>mass </em><em>= 3 kg</em>
P.E = 3 x gh
P.E = 3gh
Thus, when the mass of the cylinder increased by a factor of 3, the gravitational potential energy increases by a factor of 3.
