If the ball travels 19.6 meters every second and it travels for 3 seconds, obviously you have to multiply the velocity by 3:
19.6 x 3= 58.8m/s
Answer:
electromagnet: A magnet made of an insulated wire coiled around an iron core (or any magnetic material such as iron, steel, nickel, cobalt) with electric current flowing through it to produce magnetism. The electric current magnetizes the core material.
Explanation:
Yelling rude comments to the winning team or claiming the winning team cheated is one example. Another example could be something like crying about loosing and throwing a hissy fit over not winning
Answer:
Explanation:
The magnetic dipole moment of a circular coil with a current is given by
where
I is the current in the coil
is the area enclosed by the coil, where
is the radius of the coil
So the magnetic dipole moment can be rewritten as
(1)
Here we can assume that the magnetic dipole moment of Earth is produced by charges flowing in Earth’s molten outer core, so by a current flowing in a circular path of radius
Here we also know that the Earth's magnetic dipole moment is
Therefore, we can re-arrange eq (1) to find the current that the charges produced:
The part of a river that would have animals with muscular bodies and adaptations that let survive in turbulent water is in the transition zone, the mid-transition zone to be precise.
Water at the source zone possesses a lot of potential energy and as it flows from the upper reaches the potential energy is turned into kinetic energy when the course of the river begins to gradually level out and this translates into increase in velocity. By the time river water reaches the middle of the transition zone, most of the potential energy would have been turned into kinetic energy and thus water velocity would be quite high here.
Animals living here would develop muscles because of constantly fighting against the strong current to avoid being swept downstream.
