<h3><u>Answer;</u></h3>
Perpendicular
<h3><u>Explanation;</u></h3>
- The crest of a water wave moves <u>perpendicular</u> to the direction the wave energy moves.
- A transverse wave is a wave in which particles move up and down or side-to-side at right angles or perpendicular to the direction the wave travels.
- Examples of these waves are: vibrations in strings, ripples on water surface and electromagnetic waves. In a transverse wave, the particles of the medium oscillate in a direction perpendicular to the direction of propagation.
Answer:
Option B, to establish the reference polarity for induced voltages
Explanation:
Dot basically indicates the polarity of the electrical windings. Currents entering and leaving the same dotted ends will produce magnetic flux in same direction while the current entering at one dotted end and leaving at another dotted end will produce opposing magnetic flux.
Thus it is clear that dot represents the terminals having same phases of induced AC voltages so that only one winding is loaded at a time.
Hence, option B is correct
Answer:
distance travelled 7 metres and
displacement 3 metres
Explanation:
Distance travelled is the total diatance travelled by you which is 2m + 5m = 7m
Displacement is the shortest distance between two points start and stop which is 3m.
A. elastic motion because that's the answer
Answer:
It is wrong to say that "a single object all alone is moving" simply because it goes against Newton's law of inertia.
Explanation:
From Newton's law of inertia, it states that: An object at rest or in constant motion will continue in it's present state unless it is acted upon by an external force.
Which means that a single object by itself cannot move anywhere unless it is acted upon by an external force..
Thus, it is wrong to say that "a single object all alone is moving" simply because it goes against Newton's law of inertia.
