Answer:
Conduction
Explanation:
Conduction. When a substance is heated, its particles gain internal energy and move more vigorously. The particles bump into nearby particles and make them vibrate more. This passes internal energy through the substance by conduction , from the hot end to the cold end.
Answer:
Gravity and Friction
Explanation:
How gravity and friction work which u probably know
When you hit a hammer on the head of a nail, all the momentum associated with hammer is transferred into nail. And due to this, the surface of nail gets deformed or if you touch it you can feel the rise in temperature. When you hit a hammer on nail, hammer exerts force on nail and by Newton's 3rd law, nail will also exert a force on the hammer perpendicular to the surface of the hammer of same magnitude but its direction will be reversed. Thus, only 2 forces acts in this interaction and they are action-reaction pairs.
Answer:
<u>2.48 m</u> is the length of the rope.
Explanation:
Cycle period is 321
Time is 20 second
Wave travels at speeds = 26.4 m/s
We know that,
Frequency required for 321 complete cycle in 20 seconds is
Frequency = 16.05 hz
We know that,
λ = wavelength, the distance between "wave crests" (m)
v = wave velocity, the "speed" that waves are moving in a direction (m/s)
f = frequency, (cycles/ or Hz)
λ = 1.65 m
As per given question "length of the rope has three equal length segment"
Length of the rope = 2.48 m
Therefore, length of the rope is <u>2.48 m.</u>
