Answer:
Explanation:
In electric circuit , the potential difference is always developed across the resistance .
Now is we are to amplify the voltage , that means low input voltage is converted into high voltage output .
Therefore we require low resistance at input for low voltage and high out put resistance for high output
Thus the statement given is wrong .
Answer:
Momentum is conserved in all three physical directions at the same time.
Explanation:
There is a peculiarity, however, in that momentum is a vector, involving both the direction and the magnitude of motion, so that the momenta of objects going in opposite directions can cancel to yield an overall sum of zero.
Answer:
Must be put in to break the bonds in the reactants and the energy that is released upon making the bonds in the products.
Explanation:
The heat energy is absorbed to break the chemical bonds, which are responsible for the attractive interactions between atoms and molecules, and which gives stability to chemical compounds. While the heat energy is released upon making the bonds in the chemical compounds.
In the opposite figure, the work done by the force F to push the box upwards from the ground to the top of the inclined plane is 600 J.Option c is correct.
<h3>What is work done?</h3>
Work done is defined as the product of applied force and the distance through which the body is displaced on which the force is applied.
The displacement value from the triangle is;
The work done is found as ;
The force F in the opposing figure does 600 J of effort to lift the box from the ground to the top of the inclined plane.
Hence option c is correct.
