A hole is drilled in a copper sheet. The diameter of the hole is 4.24 cm at 27 °C. What is the change in the diameter of the hole when the sheet
Given: d1 = 4.24 cm, ∆T = 227 – 27 = 200 °C, α = 1.70 × 10-5 °C-1 To find: Change in diameter (∆d) Formula: α = \(\frac{d_2-d_1}{d_1\triangle T}=\frac{\triangle d}{d_1 \triangle T}\) Calculation: From formula. ∆d =...

Mustard was growing in two fields- A and B. While Field A produced brown coloured seeds, field B produced yellow coloured seeds.
In field A, the reason for parental trait in consecutive generations of the offsprings is self-pollination. In field B, variation is seen to occur because of recombination of genes as cross...

What are some features of n-type semiconductor?
1. These are materials doped with pentavalent impurity (donors) atoms. 2. Electrical conduction in these materials is due to majority charge carriers i.e., electrons. 3. The donor atom loses electrons and becomes...

Can we take one slab of p-type semiconductor and physically join it to another n-type semiconductor to get p-n junction?
1. No. Any slab, howsoever flat, will have roughness much larger than the inter-atomic crystal spacing (~2 to 3 Å). 2. Hence, continuous contact at the atomic level will not be possible....
