Work = Force x Distance
Force = Mass X Gravity (Near earth approximation)
So
Work = 30kg x 9.8 m/s2 x 20m = 5880 joules
the average height would be 5'6 after research was done in 1930 and found the average human height to set at. No further research has been done to change the height to todays height

No I don't think so. I think you should ask your doctor about that question. But, I'm pretty sure you can not.
Honestly, there's no way of knowing that unless Ray Toro states it in an interview which he never has done.
No, a person is done growing by the time they hit 28 years old. If a person does continue to grow, it is due to a medical condition.
The potential energy of the book on the shelf is equal to the work done to lift the book to the shelf. This is because the potential energy of an object at a certain height is equivalent to the work done against gravity to lift it to that height.
Work = (force) x (distance) (300 poundforce) x (60-ft) = 18,000 foot-pounds
Cowboys loved a colorful phrase! This means quickly, with energy. A cowboy had to move like bricks when there was work to be done.
Depends on how much is done and how big the house is.
They work everywhere.
Brick makers actually make bricks by hand. This is done by mixing the materials and pouring into molds to fire and harden. These bricks will be used for constructing homes and buildings.
yes we do work because work is done against the gravitational field in this case which is equal to w=mgh.

It is the same - work done is weight x height and potential energy change is the same at the new height
Are you the right weight for your height? It's important to know if you're the right weight for your height. This can be done by calculatating your BMI.
Yes, however it is very unlikely in day to day life. It could be done if the nessesary calcualtions are perfromed and an object is dropped from a precise height so that in a moment of time, its gravitational potential energy is equal to it's current kinetic energy. An even simpler way of making these energies equal is driving a car over a bridge of a known height and keeping the car at such a speed that its Ke is equal to it's GPe so that Ke=GPe
