Answer:
what is the question ? That is only a statement
Answer:The correct options are:
1. A system is a group of objects analyzed as one unit.
2. Energy that moves across system boundaries is conserved.
Explanation:
A system is defined as group of interrelated or interacting items existing as a single unit or a whole to achieve a specific objective.Energy lost by the system is equal to the energy gained by the surroundings.
Two statements are true about a system:
- A system is a group of objects analyzed as one unit.
- Energy that moves across system boundaries is conserved.
here the answer to your question hope it helps you
electric circuit
Answer:
- It can put out more force than the input force by decreasing the distance through which force is applied.
- It can apply a force to an object in a different direction than the force applied to the machine.
Explanation:
Assuming the machine is a simple machine, such as a lever or pulley, the machine will not do any more work than is put into it. However, it can change the magnitude or direction (or both) of the input force required to achieve a particular output force.
Because the machine does not increase the work done, if the output force is greater, the output distance must be less.
The applicable observations are ...
- It can put out more force than the input force by decreasing the distance through which force is applied.
- It can apply a force to an object in a different direction than the force applied to the machine.
