Answer:
Electric current can best be induced in a wire by moving a magnet up and down near the wire is the correct answer.
Explanation:
Electric current is the flow of electron that carries the negative charge in the electric circuit.
Electric current induced in the wire through:
- Electric current is induced in the wire when the magnet moves in and down of the wire that is connected to a very high resistance voltmeter and when we move the magnet up and down the magnetic flux gets change and these changes produce induced current
- When the coil of wire is put in the magnetic field which is changing then the current will be induced in the wire.
D.Simple Machine, is right.
When you push a door closed it doesn't travel in a straight line it turns around the hinges this is an example of a line
The final volume of the gas is 3 L
Explanation:
We can solve this problem by applying Boyle's law, which states that:
"For a gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"
Mathematically:
where
P is the pressure of the gas
V is its volume
The equation can also be rewritten as
For the sample of helium in this problem, we have:
Solving the equation, we can find , the final volume of the gas:
