I would say A, although it depends on what kind of machine. If it does not recycle, then most likely C. I would be able to give more context based on what kind of machine it is.
I’m not completely sure but I think the answer is car. Hope this helps!
For the answer to the question above, Due to water's polarity, water can absorb heat without a significant temperature change. <span>The specific heat of liquid water is 4.183 J / g K
I hope my answer helped you with your problem. Have a nice day!</span>
Answer:
greater from magnet B to A
Given:
rod of circular cross section is subjected to uniaxial tension.
Length, L=1500 mm
radius, r = 10 mm
E=2*10^5 N/mm^2
Force, F=20 kN = 20,000 N
[note: newton (unit) in abbreviation is written in upper case, as in N ]
From given above, area of cross section = π r^2 = 100 π =314 mm^2
(i) Stress,
σ
=force/area
= 20000 N / 314 mm^2
= 6366.2 N/mm^2
= 6370 N/mm^2 (to 3 significant figures)
(ii) Strain
ε
= ratio of extension / original length
= σ / E
= 6366.2 /(2*10^5)
= 0.03183
= 0.0318 (to three significant figures)
(iii) elongation
= ε * L
= 0.03183*1500 mm
= 47.746 mm
= 47.7 mm (to three significant figures)
