There are 2.6\times 10^{4} spectators in the soccer stadium.

Step-by-step explanation:

From this statement, we can calculate the number of spectators in a soccer stadium by dividing the amount of bacteria among the spectators in a soccer stadium by the amount of bacteria in the human body. That is:

x = \frac{2.6\times 10^{18}\,bacteria}{1\times 10^{14}\,bacteria}

x = \frac{2.6}{1}\times \frac{10^{18}}{10^{14}}

x = 2.6\times 10^{18-14}

x = 2.6\times 10^{4}

There are 2.6\times 10^{4} spectators in the soccer stadium.

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

30% of 420 are first year students

first year students = (30/100 )*420

=126 students

Student who are not in first year = 420-126

=294 students
