Answer:
The new distance is     d = 0.447 d₀
Explanation:
The electric out is given by Coulomb's Law
          F = k q₁ q₂ / r²
This electric force is in balance with tension.
We reduce the charge of sphere B to 1/5 of its initial value ( =q₂ = q₂ / 5) than new distance (d = n d₀)
=q₂ = q₂ / 5) than new distance (d = n d₀)
dat
      q₁ = 
      q₂ = 
      r = d₀
In order for the deviation to maintain the electric force it should not change, so we apply the Coulomb equation for the two points
          F = k q₁ q₂ / d₀²
          F = k q₁ (q₂ / 5) / (n d₀)²
          .k q₁ q₂ / d₀² = q₁ q₂ / (5 n² d₀²)
           5 n² = 1
           n = √ 1/5
           n = 0.447
The new distance is
          d = 0.447 d₀
 
        
             
        
        
        
Answer: 1.2 m/s
Explanation:
Velocity  is defined as the variation of position of an object or body in time. So, if we know the distance the seed traveled and the time, we can calculate its velocity:
 is defined as the variation of position of an object or body in time. So, if we know the distance the seed traveled and the time, we can calculate its velocity:

Where:
 is the distance the maple seed traveled
 is the distance the maple seed traveled
 is the time
 is the time
Then:

 This is the seed's velocity
 This is the seed's velocity
 
        
             
        
        
        
Answer:
The formula for force according to Newton's second law of motion is F=ma or force for an object to move is equal to mass times acceleration.
Acceleration or average acceleration defined as change in velocity per time.
F=ma
F=1.2x10³kg*(20m/s)(1/5s)=4.8x10³  Newtons

fthat's not the answer then i'm sorry
