Answer:
The Machine exerts a force of 9N.
Explanation:
Initial velocity (u) = 0 m/s
Final velocity (v) = 30 m/s
Time (t) = 0.5 s
Acceleration (a) = (v-u)/t
= (30-0)/0.5 m/s²
= 30/0.5 m/s²
= 60 m/s²
Mass = 0.15 kg
Force = Mass*Acceleration
= 0.15*60 N
= 9 N
Explanation:
Richard has conducted a study in which he compares the reading skills of six- year-olds, seven-year-old, and eight-year-olds-<u>They use one-way ANOVA Test</u>
Explanation:
The one-way analysis of variance also known as the ANOVA test is used to determine if there is any any statistically difference between the means of two or more independent or unrelated groups/variables
It is to be noted that there has to be minimum three groups rather than two groups

Factors of production are resources or inputs put into the production of goods and services. There are four factors of production. They are: land, labour, capital and entrepreneurship
Land is considered a non depreciablle factor of production. It refers to all natural resources or gifts of nature and income from it is called rent.
Labour is human capital or input in production example workers in a factory
Capital is man made goods utilized to produce other goods
Entrepreneurship/entrepreneur is the factor of production that organizes the other factors of production and carries the economic risk
From the example, the factors of production include:
The forest with all the wood which falls under land factor of production.
Bill who falls under labour factor of production
His father's chainsaw which falls under capital factor of production
Bill's idea to use logs of wood for Christmas tree business constitutes entrepreneurship and Bill is also the entrepreneur here. This falls under the entrepreneurship factor of production
There was both guerilla warfare and trench warfare in this global war
