A wedge is a machine and it is used for separating bodies.
<h3 /><h3>
The Wedge as a Machine</h3>
The wedge is a combination of two inclined planes. When the wedge is driven into a body by an effort force, a much larger force will be exerted to each side by the wedge surfaces.
What are the importance of wedge?
A wedge is used to separate bodies which are held together by large forces example of this scenario is splitting of timber. A wedge is a machine and the example of wedge - type of machine are;
Note that a thin wedge has a higher mechanical advantage than a short thick one.
Therefore, a wedge is a machine and it is used for separating bodies.

Answer:
1) Speed in m/s equals 22.22 m/s.
2) Speed in miles per hour equals 49.712 mph.
Explanation:
Since we know that in 1 kilometer there are 1000 meters and in 1 hour there are 3600 seconds hence we can write

Now we know that 1 mile equals 1.609 kilometer hence we conclude that 1 kilometer equals
mile
Hence

Answer:
<em>The velocity of the ball as it hit the ground = 19.799 m/s</em>
Explanation:
Velocity: Velocity of a body can be defined as the rate of change of displacement of the body. The S.I unit of velocity is m/s. velocity is expressed in one of newtons equation of motion, and is given below.
v² = u² + 2gs.......................... Equation 1
Where v = the final velocity of the ball, g = acceleration due to gravity, s = the height of the ball
<em>Given: s = 20 m, u = 0 m/s</em>
<em>Constant: g = 9.8 m/s²</em>
<em>Substituting these values into equation 1,</em>
<em>v² = 0 + 2×9.8×20</em>
<em>v² = 392</em>
<em>v = √392</em>
<em>v = 19.799 m/s.</em>
<em>Therefore the velocity of the ball as it hit the ground = 19.799 m/s</em>
Answer:
9.6 km/h
Explanation:
20 minutes=1/3 minute.
The speed of the bicycle: 3.2:1/3=9.6 km/h.
