It translates as: The net force on an object is equal to the mass of the object multiplied by the acceleration of the object. Or some simply say: Force equals mass times acceleration….

Q. How many mA is a?
Milliampere to Ampere Conversion Table
| Milliampere [mA] | Ampere [A] |
|---|---|
| 20 mA | 0.02 A |
| 50 mA | 0.05 A |
| 100 mA | 0.1 A |
| 1000 mA | 1 A |
- Force is measured in Newtons, N.
- Mass is measured in kilograms, kg.
- Acceleration is measured in meters per second squared, m/s2.
Q. How do you calculate Ma?
To determine its mechanical advantage you’ll divide the length of the sloped side by the width of the wedge. For example, if the slope is 3 centimeters and the width is 1.5 centimeters, then the mechanical advantage is 2, or 3 centimeters divided by 1.5 centimeters.
Q. Which one is correct formula for Mech efficiency?
Mechanical Advantage – To calculate the mechanical efficiency, divide the output work by the input work, then you have to multiply it by 100.
Q. What is called efficiency?
Efficiency is the fundamental reduction in the amount of wasted resources that are used to produce a given number of goods or services (output). Economic efficiency results from the optimization of resource-use to best serve an economy.
Q. Why efficiency is always less than 1?
Since a machine does not contain a source of energy, nor can it store energy, from conservation of energy the power output of a machine can never be greater than its input, so the efficiency can never be greater than 1.
Q. What is called mechanical efficiency?
Mechanical efficiency, measure of the effectiveness with which a mechanical system performs. It is usually the ratio of the power delivered by a mechanical system to the power supplied to it, and, because of friction, this efficiency is always less than one.
