Physics two experiment questions
2
Question one
Scientific notation is a way of expressing huge and small numbers easily so that they can be
easily compared and use in computation. It can express in terms of; N* n^c
Where N = number and 1 ≥N < 10
n= 10
c= an integer (can be a positive or a negative number)
A significant number is any number that is beginning with a nonzero number and ending with
either nonzero number of a zero number that is considered as an exact number.
Part a
37.60
Scientific notation = 3.760*10^1
Significant number = 3
Part b
0.001300
Scientific notation =1.300*10^-3
Significant number = 2
Part c
1300
Scientific notation =1.3*10^3

Significant number = 4
Part d
1.2300
Scientific notation = 1.2300*10^0
Significant number = 3
Question two
Part a
37.6*1.23
Applying the rule of multiplication of significant figures.
Rule 1
considering the first number of multiplications 37.6 which has 3 significant number, we have;
37.6 *1.23 =46.248 = 46.2
Rule 2
Considering the second number of multiplications 1.23 which also has 3 significant numbers
hence, 337.6*1.23 = 446.248 =46.2
37.6 *1.23 = 46.2 with 3 sign...
