In a pulley system, a 5-newton weight is to be lifted 2 meters. the rope is pulled 10 meters. the input force is two newtons.

the ima = .

the ama = .

the efficiency = %.

Explanation:

It is given that,

Input force,

Output force,

Input distance,

Output distance,

1. IMA of a machine is the ratio of input distance to the output distance. It is given by :

2. AMA is the actual mechanical advantage of the machine. It is the ratio of output force to the input force. It is given by :

3. The efficiency of the machine is the percentage of output work to the input work.

Hence, this is the required solution.

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
