In Star Wars, John Williams used the Leitmotif concept of romantic opera in which a character is assigned a short melody.
It is used for famous characters like Darth Vader, Princess Leia, and Han Solo all have their melody.
Leitmotif is generally described as a recurring theme shown or appears over musical or literary composition.
Leitmotif is more common in operas and symphonic poems. It is attributed to a specific person, idea, or situation.
Hence, in this case, it is concluded that in the movie Star Wars, John Williams used the Leitmotif concept of romantic opera.

A ball is thrown straight up from the ground with an unknown velocity. It returns to the ground after 4.0 s. With what velocity did it leave the ground?
Answer:
It must return at the same velocity with which it was thrown or else there would be a preferred direction of motion leading to perpetual motion.
a = (v2 - v1) / t = (v2 - 0) / 2 = v2 / 2 for a falling object
v2 = 2 a = 2 sec * 9.8 m/sec^2 = 19.6 m/s
You can check with
H = V0 t - 1/2 g t^2 (V0 and g are in different directions)
H = 0
V0 = 1/2 g * 4 = 19.6 m/s

what makes it difficult to see Mercury
Answer:
Mercury is the planet nearest the Sun and is the most difficult to observe, because it is always quite close to the Sun in the sky. Because of its orbital motion, it appears to swing back and forth around the Sun, reaching a maximum angular distance of about 28°.
Explanation:
I hope that helps you
Answer:
Mercury is very close to the Sun which means its hard to see the planet without the Sun's brightness outshining it. It is also the smallest planet in the solar system.
Hope this helps!

Answer:
P1 = momentum before collision = .5 kg * .32 m/s = .16 kg-m/s
Momentum is conserved
P1 = P2 = V * (M + m) = .16 kg-m/sec
V = .16 kg-m/sec / (.5 kg + .3 kg) = .2 m/sec

Explanation:
if the electron affinity for an element is a negative number, does it mean that the anion of the element is more stable than the neutral atom?
No, the anion of the element is more stable than the neutral atom but an electron in an atom or ion is lower in energy than a free electron.
We know that,
Kinetic energy is defined as the energy of the object that occurs due to the motion of the object. The total work needed by the body to starts accelerating it by the help of given mass which is supplied from the rest position and its mentioned velocity.
The energy body gets due to the process of acceleration by this the body will able to main the kinetic energy of the body without changing the speed of the body.
The energy which has been stored in the body or any object by the help of the particular position or the proper arrangement of the parts is known as potential energy.
There will be no effect of the outside environment on the potential energy that present inside the body.
The kinetic energy decrease or increase with change into the velocity.
Therefore, No, the anion of the element is more stable than the neutral atom but an electron in an atom or ion is lower in energy than a free electron.

write the importance of international Bureu of weights and Measures in the country.
Answer:
International Bureau of Weights and Measures (BIPM), French Bureau International des Poids et Mesures, international organization founded to bring about the unification of measurement systems, to establish and preserve fundamental international standards and prototypes, to verify national standards, and to determine fundamental physical constants. The bureau was established by a convention signed in Paris on May 20, 1875, effective January 1876. In 1921 a modified convention was signed.

What do you think will happen to current if we increase or decrease the resistance of the connecting wire?
Answer:
If resistance is increased, the current decreases and if the resistance is decreased, the current flowing through the wire increases.
Explanation:
V = IR is ohm's law which implies I = V/R, where I is the current and V is the voltage and R is the resistance. Hence, I is inversely proportional to R.
A projectile is shot on level ground with a
horizontal velocity of 17 m/s and a vertical
velocity of 34 m/s.
-Find the time the projectile is in the air.
The acceleration due to gravity is 9.8 m/s2.
Answer in units of s.
-Find range R.
Answer in units of m.
Answer:
time rising = 34 / 9.8 = 3.47 sec
total time in air = 2 * 3.47 sec = 6.94 sec
(time rising must equal time falling)
R = 17 m/s * 6.94 s = 118 m
Can also use range formula
R = v^2 sin (2 theta) / g
tan theta = 34 / 17 = 2
theta = 63.4 deg
2 theta = 126.9 deg
sin 126.9 = .8
v^2 = 17^2 + 34^2 = 1445 m^2/s^2
R = 1445 * .8 / 9.8 = 118 m agreeing with answer found above
