Two holes of unequal diameters d1 and d2 (d1 > d2) are cut in a metal sheet. If the sheet is heated, (a) both d1 and d2 will decrease (b) both d1 and d2 will increase (c) d1 will increase, d2 will decrease (d) d1 will decrease, d2 will increase Q2. In the previous question, the distance between the holes will (a) increase (b) decrease. (c) remain constant (d) may either increase or decrease depending on the positions of the holes on the sheet and on the ratio d1/d2
