Each half-life results in ~50% (1/2) of the original element remaining.
7500/1250 = 6 half-lives, so 100(1/2)^6
= 100(0.015625)
= 1.5625% of the original element would remain
The percentage of glucose given is m/v. This means that the given percentage of volume consists of mass.
In this solution, percentage of glucose is 5.5% m/v.
This means that 5.5% of the volume is the mass of glucose.
Given volume is 285 mL.
Therefore mass of glucose is 5.50% of 285 mL = (5.5*285)/100
mass of glucose = 15.67 g
I literally is 1000 ml. Therefor 1.2 literally is 1.2*1000 which is 1200 ml
Data:
F = 150 N
a = 5 m/s^2 (I corrected the units of acceleration)
m = ?
Formula: F = m*a (second Law of Newton).
Solution:
F = m*a => m = F / a
=> m = 150 N / 5 m/s^2 = 30 kg
Answer: the combined mass of the tricycle and toddler is 30 kg.
