The potential energy decreases while the kinetic energy increases.
Answer:
Difference threshold or also Just Noticeable Difference
Explanation:
The above mentioned case between room mates, where one room mate was able to detect a minute change in volume shows an instance of the difference threshold.
Difference threshold can be defined as stimulation at its minimum level that can be detected by an individual almost 50 % of the times.
It is the lowest possible level of sound that is detectable by a person.
That is what happened in the mentioned case that when the volume was increased from 14 to 15, Amber was able to detect it.
Answer:
c. increase momentum
Explanation:
When cars bounce off each other, or rebound, there is a larger change in momentum and therefore a larger impulse. A larger impulse means that a greater force is experienced by the occupants of the cars. When cars crumple together, there is a smaller change in momentum and therefore a smaller impulse.
Based on the nature of constructive interference,
none of the wave intersections will produce constructive interference.
<h3>What is constructive interference?</h3>
Constructive interference is interference that occurs when two waves of the same frequency amplitude and wavelength travelling in the same direction are superposed with the resultant effect of reinforcement of both waves to produce a larger wave.
Constructive interference occurs when the path difference between two identical waves at a point is:
where n = 0, 1, 2, ...
For the various intersections:
- 1.77 cm crest intersecting with a 0.65 cm crest; n = 1.77/0.65 = 2.7
- A 1.2 mm crest intersecting with a 3.9 mm trough is destructive.
- A 4.55 N trough intersecting with a 1.59 N trough; n = 4.55/1.59 = 2.8
- A 0.44 inch trough intersecting with a 0.72 inch crest is destructive.
- A 7.42 mm trough intersecting with a 1.93 mm trough; n = 7.42/1.93 = 3.8
Therefore, none of the wave intersections will produce constructive interference

Answer:
Two
Explanation:
A neutral point is a point in the magnetic field of a bar magnet where the resultant magnetic field intensity is zero
The neutral point is formed in the region of the combined magnetic field where the magnetic field from the bar magnet is balanced by the horizontal component from the Earth's magnetic field
Two neutral points are formed adjacent to the north and south poles of a bar magnet when the south pole of the bar magnet points in the magnetic north pole of the Earth with the north pole of the bar magnet pointing towards the south pole of the Earth's magnetic field
Two neutral points are also formed on the west and eastern facing sides of a bar magnet when the north pole of the magnet is pointing to the magnetic north of the Earth's magnetic field and the south pole of the bar magnet points south
Therefore, two neutral points are formed for each orientation of the bar magnet when placed horizontally in the Earths magnetic field with the poles of the magnet facing the North and South poles direction of the Earth's magnetic field.
