a geosynchronous satellite appears to remain over one spot on earth. a geosynchronous satellite has an orbital radius of 4.23 ×
Natasha2012 [34]

Given that,

radius, r = 4.23 x 10∧7 m

Period, T = ?

Since, we know that,

In a geosynchronous satellite, period is equal to the period of earth that is 24 hrs.

Therefore, Time period is equal to 24 hours.

serg [7]

Answer:

At the instant shown in the diagram, the car's centripetal acceleration is directed is discussed below in detail.

Explanation:

The direction of the centripetal acceleration is in a circular movement is forever towards the middle of the roundabout pathway. In the picture displayed, the East direction is approaching the center. So, the course of the car's centripetal acceleration is (H) toward the east.

A solenoid that is 133 cm long has a radius of 2.99 cm and a winding of 1740 turns; it carries a current of 3.91 A. Calculate th
erica [24]

Answer:

The value is  B = 0.0643 \ T  

Explanation:

From the question we are told that

   The length of the solenoid is  L =  133 \  cm  = 1.33 \  m

     The radius is  r = 2.99 \  cm   = 0.0299 \  m

     The number of turns is N  = 1740 \ turns

     The current it carries is  I = 3.91 \ A

Generally the magnitude of the magnetic field is mathematically represented as

           B = \frac{\mu_o *  N  * I}{L}

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

=>      B = \frac{  4\pi * 10^{-7} * 1740  * 3.91}{0.133}  

=>      B = 0.0643 \ T
