Bruno the bat flies at a speed of 0.5 m/s in circle of radius 1 m. What is his acceleration?
beks73 [17]

Answer:

Acceleration is 0.25m/s^2

Explanation:

Given the following :

Speed = 0.5m/s

Radius(r) of circle = 1m

Acceleration round a circular path is given as :

a = v^2 / r

Where

a = acceleration of the body

v = speed / velocity

r = radius

Therefore,

a = v^2 / r

a = (0.5)^2 / 1

a = 0.25m/s^2

A tightly wound toroid of inner radius 1.2 cm and outer radius 2.4 cm has 960 turns of wire and carries a current of 2.5 A.
OLEGan [10]

Answer:

a

  B  = 0.0533 \ T

b

  B  =  0.04 \ T

Explanation:

From the question we are told that

   The inner radius is r = 1.2 \ cm = 0.012 \ m

   The  outer radius is  r_o  =  2.4 \ cm  =  \frac{2.4}{100} =  0.024 \ m

    The nu umber of turns is  N  =  960

    The current it is carrying is  I =  2. 5 A

Generally the magnetic field is mathematically represented as

      B  =  \frac{\mu_o  *  N* I  }{2 * \pi * r  }

Where  \mu_o is the permeability of free space with a constant value    

            \mu  =   4\pi * 10^{-7} N/A^2

And the given distance where the magnetic field is felt is  r =  0.9 cm  =  0.009 m

Now  substituting values

     B  =  \frac{  4\pi * 10^{-7}  *  960* 2.5  }{2 * 3.142 * 0.009  }

    B  = 0.0533 \ T

    Fro the second question the distance of the position considered from the center is  r =  1.2 cm  =  0.012 m

So the  magnetic field is  

        B  =  \frac{  4\pi * 10^{-7}  *  960* 2.5  }{2 * 3.142 * 0.012  }

        B  =  0.04 \ T

What does the term electron orbital describe? What does the term electron orbital describe? An electron orbital describes a thre
Yuliya22 [10]

Answer:

An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.

Explanation:

According to Heisenberg's theory we cannot observe the position and velocity of an electron in an orbit, but if they were around the nucleus (in orbit), it would be possible to know its velocity and position, which would be contrary to the principle of Heisenberg So we can say that no electron revolves around a certain orbit around the nucleus, so we can only predict if the electron will be in the right position at the right time.

From there we find two definitions for electron orbital let's see:

  • Orbital is considered the region of space, where each electron spends most of its time.
  • Orbital is considered the region of space that is most likely to find an electron.
