Answer:
1. A blacksmith fixes iron ring on rim of wooden wheel of a horse cart. The
diameter of rim and iron ring are 3.453 m and 3.441 m respectively at
0°C. To what temperature should the ring be heated so as to fit on rim of
wheel? (afe = 1.20 x 10-5 K-1)
1) 290.6°C
2) 260.5°C
3) 330.4°C
4) 435.6°C
Can you solve this question plz .
2. A rod of length 2 m is pivoted at one end A and freely rotated in
horizontal plane at an angular velocity of 6 rad s=1, about vertical axis
passing point A. Suddenly temperature of system is increased by 200°C.
The percentage change in its angular speed is nearly
(a = 3 x 10-4K-1)
18.6%
41%
12%
36%
3. A tungsten lamp is at 3000 K and its surface area is 0.3 cm2. The
emissivity found experimentally for tungsten lamp is 0.4. The rate at
which heat is radiated from lamp is proportional to
3000^4
3273^4
2730^4
2727^4
