Answer:
Explanation:
Given:
The two rods could be approximated as a fins of infinite length.
TA = 75 0C θA = (TA - T∞) = 75 - 25 = 50 0C
TB = 55 0C θB = (TB - T∞) = 55 - 25 = 30 0C
Tb = 100 0C θb = (Tb - T∞) = (100 - 25) = 75 0C
KA = 200 W/m · K
T∞ = 25 0C
Solution:
The temperature distribution for the infinite fins are given by
θ/θb=e⁻mx
θA/θb= e-√(hp/A.kA) x1 ....................(1)
θB/θb = e-√(hp/A.kB) x1.......................(2)
Taking natural log on both sides we get,
Ln(θA/θb) = -√(hp/A.kA) x1 ...................(3)
Ln(θB/θb) = -√(hp/A.kB) x1 .....................(4)
Dicving (3) and (4) we get
[ Ln(θA/θb) /Ln(θB/θb)] = √(KB/KA)
[ Ln(50/75) /Ln(30/75)] = √(KB/200)

Answer:
Most of Our Grain is Being Consumed by Animals, Not Humans. How the Planting of Crops Used to Feed Livestock is Contributing to Habitat Destruction.
Explanation:
The major feed grains are corn, sorghum, barley, and oats.
Answer:
the three part are mass, spring, damping
Explanation:
vibrating system consist of three elementary system namely
1) Mass - it is a rigid body due to which system experience vibration and kinetic energy due to vibration is directly proportional to velocity of the body.
2) Spring - the part that has elasticity and help to hold mass
3) Damping - this part considered to have zero mass and zero elasticity.
