The velocity of the wave also increases, because molecules at higher temperatures have more energy.
Answer:
The speed of transverse waves in this string is 519.61 m/s.
Explanation:
Given that,
Mass per unit length = 5.00 g/m
Tension = 1350 N
We need to calculate the speed of transverse waves in this string
Using formula of speed of the transverse waves
Where, = mass per unit length
T = tension
Put the value into the formula
Hence, The speed of transverse waves in this string is 519.61 m/s.
<span>Operant conditioning by Burrhus Frederick
Skinner, showed that people learn to behave in certain ways because of
reinforcement. This a product of a psychology school of thought, behaviorism,
which comes in the notion that whatever a person behave is what matters instead
of his mind, pioneered by John B. Watson. If a person wants to retain the
behavior, then he will do positive reinforcements example, positive stroking.
If the behavior is undesired and needs to be exterminated, then a punishment will
be instilled.</span>

(but this is only if it's a free fall, which we assume since we didn't get the mass of the hulk)
Answer:
D,E,F
Explanation:
d. Earth's geographic north pole is actually a magnetic south pole.
e. The south poles of two bar magnets will repel each other.
f. The north pole of a bar magnet will attract the south pole of another bar magnet.
In a magnetic field like poles repel and unlike poles attract each other. The like poles which is south to south or north to north repel each other and the unlike poles which is north to south or south to north attract each other which makes E and F correct.
A is correct because compasses points to the North Pole when places in the Southern Hemisphere.
