Well if that’s the case and it wasn’t obvious you were using the power you could say things like being unseen while your doing it like a silent killer or maybe not having to rush in with your fists.a disadvantage would be that you could accidentally use your power and hurt an innocent person

Draw/Label a motor OR give directions in words on how to build a motor.
Nina [5.8K]

you take a length of ordinary wire, make it into a big loop, and lay it between the poles of a powerful, permanent horseshoe magnet. Now if you connect the two ends of the wire to a battery, the wire will jump up briefly.When an electric current starts to creep along a wire, it creates a magnetic field all around it. If you place the wire near a permanent magnet, this temporary magnetic field interacts with the permanent magnet's field.

Since entropy is about how energy is shared, it is important to be able to identify places where energy can be put, or degrees o
Fiesta28 [93]

Answer:

Please see answer in explanation

Explanation:

1. Since each molecule has three kinetic degrees of freedom (can move in three independent directions), the gas must have 3N DoFs.

2. Each molecule has the three kinetic degrees of freedom the monotonic atom has ­­ moving without rotating ­­ but it can also spin. There are three axes for it to spin around so we would expect three rotational degrees of freedom, but as were as above, the one about the diatomic molecule's axis doesn't count because of quantum. So we have two rotational DoFs and three kinetic, for a total of 5 per molecules. So the gas will have 5N DoFs.

3.When a spring vibrates it has two DoFs, its KE and its PE, so adding 1 vibration adds 2 DoFs per molecule, giving 7 per molecule and giving thegas 7N DoFs.

r-ruslan [8.4K]

Answer:

d = 375 m

Explanation:

The speed of sound is constant in any medium, therefore we can use the uniform motion relationships

          v = x / t

          x = v t

In this case it indicates that the time since the sound is emitted and received is t = 0.50 s, in this time the sound traveled a round trip distance

           x = 2d

          2d = v t

          d = v t/2

     

let's calculate

          d = 1500 0.5 / 2

          d = 375 m
