A long, current-carrying solenoid with an air core has 1800 turns per meter of length and a radius of 0.0165 m. A coil of 210 tu
Hoochie [10]

Answer:

The mutual inductance is  M  =  0.000406 \  H

Explanation:

From the question we  are told that

    The  number of turns per unit length  is  N =  1800

    The radius is  r = 0.0165 \ m

     The  number of turns of the solenoid is  N_s  =  210 \ turns

   

Generally the mutual inductance of the  system is mathematically represented as

       M  =  \mu_o  *  N *  N_s  *  A

Where A is the cross-sectional area of the system which is mathematically represented as

       A  =  \pi  *  r^2

substituting values

      A  =  3.142 *  (0.0165)^2

       A  =  0.0008554 \ m^2

also   \mu_o is the permeability of free space with the value  \mu_o  =   4\pi * 10^{-7} N/A^2

So  

      M  =  4\pi * 10^{-7}   *1800 *  210  *  0.0008554

      M  =  0.000406 \  H

a baby carriage is sitting on the top of a hill that is 21 m high. the carriage with a baby 75kg. the carriage has what energy?
lara31 [8.8K]

Answer:

It has potential energy

PE = 15450.75 J

Explanation:

we know its potential energy because the carriage is not moving, although it can

PE = mgh

in this case, m is 75, h is 21, and g is always 9.81

plug these in: PE = (75) (21) (9.81)

your answer: PE = 15450.75 J
