The student who displaced the spring by 2 cm has less potential energy than the student who displaced the spring by 4 cm, this is because potential energy (elastic) is directly proportionate to extension (displaced amount), so as the amount of displacement of the spring is higher, then the potential energy of the springs is higher and vice versa.
Answer:
A path that allows most of the current in an electric circuit to flow around or away from the principal elements or devices in the circuit.
The greater the mass, the greater the fiction generated
The diagram shows a simple electric generator. The needle that measures electric current will move back and forth between a largely positive and a large negative value.
- What is an electric generator?
- An electric generator is physically equivalent to an electric motor. but it converts mechanical energy into electrical energy.
- The electrical field generated is dependent on the inclination of the wire with respect to magnetic field lines, and this inclination changes over time,
because of that she will experience a varying electrical field, and thus a varying electric current will be zero.
The maximum positive value will occur when the wire is perpendicular to the magnetic field lines after one-fourth of rotation, and then zero.
Hence option C is correct.
