Answer:
66.26 kg
Step-by-step explanation:
weight = mass x g ; where g = acceleration due to gravity = 9.81 m/s²
mass = weight ÷ g
given, weight = 650 N
mass = 650 / 9.81 = 66.26 kg
Answer: B
Step-by-step explanation:
Division of components are consistent - the same
Answer:
3.2
Step-by-step explanation:
Answer: 2
Step-by-step explanation:
Recall from the laws of Logarithms:
Log a - Log b = Log ( a/b )
That means
Log 200 - Log 2 = Log ( 200/2)
= Log 100 , which could be written as
Log 
Recall from laws of Logarithms:
Log
= b Log a
Therefore:
Log
= 2 Log 10
Also from law of Logarithm
Log 10 = 1
Therefore 2 Log 10 = 2 x 1
= 2
