Inclined planes reduce the amount of effort needed to move an object, but increases the length of the ramp.
<u>Explanation:</u>
Mechanical advantage is the measure of amount of effort needed to move an object. The mechanical advantage can be calculated as the ratio of length of ramp to the height of ramp for an inclined plane.
As it is known that an object can be easily moved on an inclined plane than on a vertical plane, this is because, the inclined plane provides greater output force. But in that case, the effort required will be reduced with the cost of increasing the distance of the movement of object.
In other terms , the ramp's length of inclined planes has to get increased in order to reduce the amount of effort needed to move an object. This is because as the mechanical advantage has length of the ramp in the numerator, with the increase in numerator value or length value the mechanical advantage will also increase.
Answer:
The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.
Explanation:
A heat because heat is the transfer of energy.
Because it is a covalent bond meaning that they share the electrons to achieve full valence.
Answer: 
of PABA is 0.000022
Explanation:
cM 0 0
So dissociation constant will be:
Give c= 0.055 M and 
= ?
![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
![2.96=-log[H^+]](https://tex.z-dn.net/?f=2.96%3D-log%5BH%5E%2B%5D)
![[H^+]=1.09\times 10^{-3}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D1.09%5Ctimes%2010%5E%7B-3%7D)
![[H^+]=c\times \alpha](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3Dc%5Ctimes%20%5Calpha)
Putting in the values we get:
Thus of PABA is 0.000022
