Answer:
1.27 m
Explanation:
Distance = 192 m
number of rotations = 48
Distance traveled in one rotation = 2 x π x r
Where, r be the radius of wheel.
so, distance traveled in 48 rotations = 48 x 2 x 3.14 x r
It is equal to the distance traveled.
192 = 48 x 2 x 3.14 x r
r = 0.637 m
diameter of wheel = 2 x radius of wheel = 2 x 0.637 = 1.27 m
Answer:
Pushing molecules like a wave.
Explanation:
Answer:
Explanation:
(Assuming the cell in the circuit has 0 internal resistance)
Ohm's Law is given as:
Voltage is Current multiplied by Resistance.
We can rearrange this formula to give us:
Now we can plug in our values
Explanation:
Magnetic field is the surrounding around the magnet in which the magnetic force can be experienced.
Same poles of the magnets repel each other. The opposite poles of the magnets attract each other.
In a magnet, the magnetic field originates from the north pole and ends to south pole.
In the given problem, the south pole of a magnet get affected when a second south pole is brought near it. These poles will repel each other as both are south poles. Here, the magnetic field lines near the south pole of a magnet gets bend away from the south pole of the second magnet.
