Answer:
The original concentration of ethanol is 16%(v/v)
Explanation:
concentration before dilution, C1 = ?
Concentration after dilution, C2 = 0.32% (v/v)
Volume before dilution, V1 = x
Volume after dilution, V2 = 50x
From the dilution principle
C1V1 = C2V2
(C1) * x = (0.32) * 50x
C1 = (16x)/x
C1 = 16%(v/v)
The power deposited in a metal is proportional to its electric resistance, so high-resistance metals heat more.
sorry I dont now the answer bro i am so sorry xd ;'(
C=0.4m/s
a=v/t
0.1=v/4.0
v=0.1*4.0
V=0.4m/s
