Answer:
I feel like to demonstrate you would use an elastic band as the material. You obviously have to put force in order to see how far it stretches. From this you can also find about its resistance and durability
Also you have to make sure the distance between the two hands are equal as you want an accurate result.

Answer:
288W.
Explanation:
P = IV = V^2 / R = (120)^2 / 50 = 288W.
Nothing will happen. The mercury and steel will not move. It’s just like filling a glass halfway with cement and then pouring water on top of it.
32. P = V * I
P = 230 * 4 = 920 w
In short, Your Answer would be: 920 w
33. I = P/V
I = 48/12 = 4 A
In short, Your Answer would be: 4 Ampere
34. Now, for this part you've given Voltage & Power, and you need to calculate Current & Resistance, so you could apply two equations here:
(i) For finding Current = P/V
(ii) For resistance = V²/P
So, Current for Bulb of Study Lamp = 60/230 = 0.260 A
Resistance of Bulb of Study Lamp = 230²/60 = 881.67 Ohm
In similar manner, substitute the known values (Power & Voltage) in each case, you'll have your answers!
35. We know, P = V²/R
P = 230²/48
P = 1102.08 w
Hope this helps!
