Answer:
The  kinetic energy is 
Explanation:
From the question we are told that 
        The  radius of the orbit is  
        The gravitational force is  
The kinetic energy of the satellite is mathematically represented as 
        
where v is the speed of the satellite which is mathematically represented as 
      
=>  
substituting this into the equation 
       
Now the gravitational force of the planet is mathematically represented as 
       
Where M is the mass of the planet and  m is the mass of the satellite 
  Now looking at the formula for KE we see that we can represent it as 
      ![KE  =  \frac{ 1}{2} *[\frac{GMm}{r^2}] * r](https://tex.z-dn.net/?f=KE%20%20%3D%20%20%5Cfrac%7B%201%7D%7B2%7D%20%2A%5B%5Cfrac%7BGMm%7D%7Br%5E2%7D%5D%20%2A%20r)
=>    
substituting values 
        
          
  
 
        
             
        
        
        
Answer:
Option D
Explanation:
The work done can be given by the mechanical energy used to do work, i.e., Kinetic energy and potential energy provided to do the work.
In all the cases, except option D, the energy provided to do the useful work is not zero and hence work done is not zero.   
In option D, the box is being pulled with constant velocity, making the acceleration zero and thus Kinetic energy of the system is zero. Hence work done in this case is zero.
 
        
                    
             
        
        
        
Answer:
As the capacitor is discharging, the current is increasing
Explanation:
Lets take 
C= Capacitance 
L=Inductance
V=Voltage
I= Current
The total energy E given as

We know that total energy E is conserved so when electric energy 1/2 CV² decreases then magnetic energy 1/2 IL²  will increases.
It means that when charge on the capacitor decreases then the current will increase.
As the capacitor is discharging, the current is increasing
