No, one more group must get the same result as the other group. This will make it more reliable and reproducible.
Coffee mug is cylindrical shape. Therefore,
Volume of mug = volume of cylinder = πr²h
r = inner radius of mug. h = height of coffee = 6 cm.
Density of coffee = Density of water = 1 g/ml
Therefore, volume of coffee = mass/density = 400/1 = 400 ml = 400 cm³
Volume of coffee = πr²h
400= πr²(6)
r² = 21.23
r = inner radius of mug = 4.607 cm
Well if u see here the graph is showing us 1.5 on the graph so we multiply that by 6 and we get 46 as our final anwser
Answer:
b) n = 1 to n = 4.
Explanation:
a ) n = 4 to n = 1 transition represents release of energy because transition is from high energy orbit to low energy orbit.
Similarly c) n = 2 to n = 1 represents release of energy because transition is from high energy to low energy orbit.
d ) n = 1 to n = 3 is also energy absorbing transition but amount of energy absorbed is less as compared with option b) transition .
So the correct option is b)
