The answer to the problem is A because the velocity of the plane changes when she turns it
We can assume that all<span> gravitational potential energy is converted into
kinetic energy of the object.</span><span>
<span>Hence, </span>GPE = KE
Where GPE is gravitational Potential Energy (J)
and KE is Kinetic Energy (J)
GPE = mgh
<span>Where, m is the mass of the object (kg), g is acceleration due to gravity (9.8 m s</span></span>⁻<span>²) and h is the height to the<span> object from ground (m).</span></span><span>
m = 0.18 kg
g = 9.8 m s</span>⁻²<span>
h = 45 m
Hence,
GPE = 0.18 kg x 9.8 m s</span>⁻² x 45 m<span>
= 79.38 J
≈ 79 J
<span>Hence, </span>KE = GPE = 79 J
<span>Hence, the
answer is '79 joules'.</span></span>

A gas is something that takes up the space of the container, because it doesn't have a fixed shape.
Answer:
Neutralization reaction
Explanation:
This reaction involve an acid (HCl) reacting with a base (NaOH), producing a salt (NaCl) and water. Therefore it's a neutralization reaction.
