Q39 2.5+2.5+2.5 = 7.5 (so 3 half lives ) And if we divide 80 by 2 (3x) 40 20 10 Since it says sample decreases BY 70 so if we ad 40 +20 +10=70 which means total mass required to decrease 70 (If we divide the other options they don’t add up to 70 it’s just 80 which does)
Sir in q 14 both the values on top and bottom should have same unit to find efficiency but in this case gae and power have different units.can u please explain…

Beta gpe gained per second ka Matlab energy/time hai to yeah power ke unit mai lie kar rahi h to unit same h
