Mechanical advantage is defined as the ratio of output load to the input load. The mechanical advantage of the machine will be 0.1.
<h3>What is 
mechanical advantage?</h3>
Mechanical advantage is a measure of the ratio of output force to input force in a system, 
It is used to obtain the efficiency of forces in levers and pulleys. It is an effective way of amplifying the force in simple machines like levers.
The theoretical mechanical advantage is defined as the ratio of the force responsible for the useful work in the system to the applied force. 
Given
applied force = 250 N
Output force = 25 
Mechanical advantage = work output / work input
 


Hence the mechanical advantage of the machine will be 0.1

★ Velocity: Distance travelled by a body per unit time in given direction is called velocity .
 
 
        
                    
             
        
        
        
Answer:
As the tines of the tuning fork vibrate at their own natural frequency, they created sound waves that impinge upon the opening of the resonance tube. These impinging sound waves produced by the tuning fork force air inside of the resonance tube to vibrate at the same frequency.
 
        
                    
             
        
        
        
Hi there!
We can begin by deriving the equation for how long the ball takes to reach the bottom of the cliff. 

There is NO initial vertical velocity, so:

Rearrange to solve for time:

Plug in the given height and acceleration due to gravity (g ≈ 9.8 m/s²)

Now, use the following for finding the HORIZONTAL distance using its horizontal velocity:
