The ration of output work to input work expressed as a percentage is called <u>Efficiency</u>.
Answer:
A
Explanation:
Analytical people are less responsive to others. They hence tend to focus more on work than people and are less interested in leading, being happier to work by themselves. They may be prudent and systematic, making them good at analytic work.
Some character traits of Analytical people
Focuses on work and working more than people
Likes to be correct and will take time to ensure this
Thoughtful, careful fact-oriented and precise
Good at problem-solving
Likes organization and structure
Avoids working in a group, preferring to work alone
Can be over-critical and unresponsive
Cautious in decision-making
When stressed may withdraw or become headstrong
Answer:
In conductive materials, the outer electrons in each atom can easily come or go, and are called free electrons. In insulating materials, the outer electrons are not so free to move. All metals are electrically conductive.
as well.
1. Correct
Explanation
An inclined plane is a flat surface which lie at an angle, Its one end is higher than the other this inclined plane is used as an aid for raising or lowering a load. Staircase also work in similar manner
2. Correct
Explanation
yes all simple machine have a fulcrum
3. Incorrect
Explanation
when we swim that time our arms and legs 'push' the water due to which water displaced in backward direction so her we applied a positive work on the water. According to Newton's Third Law,same magnitude of work is done by water in opposite direction to push us back on our arms and legs. therefore water also does positive work on us.
4. incorrect
Explanation
The force exerted by a machine on an object is input force
5. Incorrect
Explanation
when the input force is greater than the output force that time machine have mechanical advantage of less than 1.
