Elena-2011 [213]

Answer:

The steady force required of each rocket is 31.36 N

Explanation:

Given that,

Mass of satellite = 3600 Kg

Radius = 4 m

Mass of rocket = 250 kg

Time = 5 min

Angular velocity = 32 rpm

We need to calculate the moment of inertia

Using formula of moment of inertia

I=\dfrac{1}{2}Mr^2+4mr^2

Where, M = mass of satellite

r = radius

m = mass of rocket

Put the value into the formula

I=\dfrac{1}{2}\times3600\times4^2+4\times250\times4^2

I=44800\ kg-m^2

We need to calculate the angular acceleration

Using formula of angular acceleration

\alpha=\dfrac{\omega}{t}

Where, \omega = angular velocity

t = time

Put the value into the formula

\alpha=\dfrac{2\pi\times32}{3600\times5}

\alpha=0.0112\ rad/s^2

We need to calculate the steady force required of each rocket

Using formula of torque

\tau=I\alpha

4rF=I\alpha

F=\dfrac{I\alpha}{4r}

Put the value into the formula

F=\dfrac{44800\times0.0112}{4\times4}

F=31.36\ N

Hence, The steady force required of each rocket is 31.36 N

A parallel-plate capacitor in air has circular plates of radius 2.8 cm separated by 1.1 mm. Charge is flowing onto the upper pla
Hatshy [7]

Answer:

The time rate of change of the electric field between the plates is  \frac{E }{t} =  2.29 *10^{14} \   N \cdot C  \cdot  s^{-1}  

Explanation:

From the question we are told that

    The  radius is  r =  2.8 \ cm  =  0.028 \ m

     The distance of separation is  d =  1.1  \ mm  =  0.0011 \ m

      The  current is  I  =  5 \ A

Generally the electric field generated is mathematically represented as

         E = \frac{q }{ \pi  *  r^2  \epsilon_o  }

Where \epsilon_o is the permitivity of free space with a value

          \epsilon_o  =  8.85*10^{-12 }\   m^{-3} \cdot kg^{-1}\cdot  s^4 \cdot A^2

So the time rate of change of the electric field between the plates is mathematically represented as

        \frac{E }{t} =   \frac{q}{t} *   \frac{1 }{ \pi  *  r^2  \epsilon_o  }

But \frac{q}{t }  =  I

So  

       \frac{E }{t} =   *   \frac{I }{ \pi  *  r^2  \epsilon_o  }

substituting values  

        \frac{E }{t} =   *   \frac{5 }{3.142  *  (0.028)^2 *   8.85 *10^{-12}  }

        \frac{E }{t} =  2.29 *10^{14} \   N \cdot C  \cdot  s^{-1}
