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.
The engine's efficiency is (35J)/125J) = 28% .

Answer: The molecules in gases are different from other states of matter
Explanation:
The molecules in gases are different from other states of matter because unlike, for example, a solid, they move around freely and are much more spread apart. A gas can fill up any container, but once the container is unsealed, the gasses will immedietly be let out. Gases can be compressed much more easily than a solid or a liquid.
The equilibrium position for a pendulum is straight down. If it moves through that position every second then its period is actually 2 seconds. This is because the period is how long it takes to go from one extreme and back again. It will pass through the equilibrium point twice when doing this. Once on the way down and again on the way back.
Answer:
0.25hr
Explanation:
Given parameters:
Distance = 200km
Time = 2hrs
Now, let us find the rate which is the speed;
Speed =
Insert parameters:
Speed =
= 100km/hr
Since the speed of Imamu = 2 x speed of Mosi = 200km/hr
Time taken =
=
= 0.25hr
