Answer:
The weight will be more on planet B because greater is the gravity more is the weight of a body 
 
        
             
        
        
        
Answer:
Therefore,
The speed of the wave on the longer wire is 95 m/s.
Explanation:
Given:
For Short wire, speed is 

Let length of Short  and Longer wire be  such that
 such that

To Find:
 Speed on the longer wire
  Speed on the longer wire
Solution:
The speed of a pulse or wave on a string under tension can be found with the equation,

Where,
 = Tension on the wire
 = Tension on the wire
L = Length of Sting
m = mass of String
So here we have,
 = same
 = same

Therefore,
 ......equation ( 1 )
 ......equation ( 1 )
And
 .......equation ( 2 )
  .......equation ( 2 )
Dividing equation 1 by equation 2 and on Solving we get

Therefore,

Therefore,
The speed of the wave on the longer wire is 95 m/s.
 
        
             
        
        
        
Answer:
2.1x10^6m/s
Explanation:
One electron has a charge of –1.602e-19 C 
mass of electron is 9.1e-31 kg 
mass of proton is 1.6726e−27 kg 
mass ratio is 1.6726e−27 / 9.1e-31 = 1838
The force is constant, F
distance is constant, d
a = F/m
a increases by a factor 1838, as m decreases by that factor
a = a₀1838
v₀² = 2a₀d
v² = 2a₀d1838
v²/v₀² = 2a₀d1838 / 2a₀d = 1838
v² = 1838v₀² = 1838(45000)² 
v = 45000√1838 = 2.1e6 m/s
