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 .
I don’t know ask your parents
Answer;
B. The field is most concentrated at the poles of the magnet
Explanation;
A bar magnet is a rectangular object that has a magnetic field. It is usually made of iron or steel, but it can also be made of any ferromagnetic substance or a ferromagnetic composite.
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
If small compasses are used to map the magnetic field around a bar magnet, they will point in the direction away from the north pole of the magnet, toward the south pole of the magnet
Answer:
Explanation:
Hello,
In this case, since the acceleration in terms of position is defined as its second derivative:
The purpose here is derive x(t) twice as follows:
Thus, the acceleration turns out 4.8 meters per squared seconds.
Best regards.
