Answer: Fibres are very thin, thread-like strands from which fabrics or cloth is made. Examples of fibres are cotton, wool, silk, flax, jute, nylon, polyester, polyacrylic. The fibres are spun into yarn which can then be woven on a Loom to make a fabric or cloth

Answer:
Tension T1 is less than tension T2.
T1 < T2
Explanation:
According to given data,
mass of box A ( mA) is grater than mass of box B (mB)
we can write,
m(A) > m(B)
Newton's second law states that:
Tension of object is directly proportional to the mass of the system.
T ∝ m
here Boxes A and B are being pulled to the right on a frictionless surface,
so Tension T1 generates due to the mass of box A m(A)
and Tension T2 arises due to mass of the system m(A) + m(B)
Thus tension T1 will be less than tension T2
T1 < T2

Answer:
If the absorbed beam is monochromatic (one wavelength) then it excites the H atom to some state n.
When that state decays, some of the atoms may decay to state 1, others to state 2, and still others to state 3
The net energy emitted in such a case would depend on:
n -1, n - 2, n - 3 which would produce 3 different wavelengths
