Answer:
Work done, W = 10195.92 Joules
Explanation:
Given that,
Mass of the crate, m = 170 kg
Distance, d = 10.2 m
The coefficient of friction, 
Let W is the work done by the mover. It is given by in terms of coefficient of friction as :


W = 10195.92 Joules
So, the work done by the mover is 10195.92 Joules. Hence, this is the required solution.
Answer:
There are 1.806 X 1024 molecules in 3 moles of CO2. This concept is similar to counting 144 eggs and dividing by 12 to get the number of cartons.
