Newton's 2nd law says:          Force = (mass) x (acceleration) .
I wrote Force and acceleration in bold letters because
they're both vectors ... they have size and direction.
The equation is saying that the Force and the acceleration
are both in the same direction.  
        
             
        
        
        
Answer:
D
Explanation:
Ball A is a non positively charged non metal while ball B is metal ball. 
Given: The ball B positive charge of small magnitude 
To prove: Balls will attract each other 
IN this condition because of induction negative charges on the sphere B move to the side closer to sphere A,(induction charging) while the positive charges move to the side further away from sphere A. The polarization of charge on B will cause a greater attractive force than the repulsion of the like charges.
Hence the correct answer will be D . 
 
        
             
        
        
        
Answer:
1.045 m from 120 kg 
Explanation:
m1 = 120 kg 
m2 = 420 kg 
m = 51 kg 
d = 3 m 
Let m is placed at a distance y from 120 kg so that the net force on 51 kg is zero. 
By use of the gravitational force 
Force on m due to m1 is equal to the force on m due to m2. 



3 - y = 1.87 y 
3 = 2.87 y 
y = 1.045 m 
Thus, the net force on 51 kg is zero if it is placed at a distance of 1.045 m from 120 kg. 
  
        
             
        
        
        
Answer:
When you look at a simple koi pond you can find Koi (the secondary consumer) that feeds off of the zooplankton (first consumer), they eat the phytoplankton (producers). All in a simple food chain
Explanation: 
Basically, Koi eat the little animal plankton (zooplankton) that then eats the plant plankton (phytoplankton) that can only end when a part of that habitat is removed. If you got rid of the plant plankton then the whole chain would collapse and most likely die.
