Explanation:
They are,
1.Moving the load closer to the fulcrum will increase the mechanical advantage.
2.Moving the effort farther from the fulcrum will increase the mechanical advantage. This may require a longer lever.
Answer:
Acceleration,
Explanation:
It is given that,
Initial speed of the jetliner, u = 69 m/s
Final speed of the jetliner, v = 6.1 m/s
Distance covered, s = 750 m
We need to find the average acceleration of the jetliner. It can be calculated using third equation of motion as :
So, the average acceleration of the plane during landing is . Hence, this is the required solution.
Answer:
Pressure = 1194.03 N/m
Explanation:
Given the following data;
Force = 800 N
Area = 0.67 m²
To find the pressure on your feet;
Mathematically, pressure is given by the formula;
Pressure = force/area
Pressure = 800/0.67
Pressure = 1194.03 N/m
Answer:
A fundamental quantity is something that can only be found by measuring, such as measuring the length of a pencil. We have no other way to find out the length of the pencil other than measuring it in some way.
A derived quantity is something that is calculated and that is not measured <em>directly. </em>Area is found by multiplying two lengths together. We cant find the area other than computing it somehow
