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: 
Explanation:
When a number is written in scientific notation (representing the number using powers of base ten) it is expressed so that it contains a digit in the place of the units and all other digits after the decimal point, multiplied by the respective exponent.  
Then, the significant figures (or significant digits) will be the digits that are before the power of ten.  
Now, in the case of the number 299,792,458 if we want to write it with three significant digits, we have to write it in scientific notation as:

Answer: The option (C) is correct. The energy travels horizontally.
Explanation: When the pebble is thrown into a calm lake, there will be disturbance in the lake. The ripples are formed from the center and move outward because the energy is carried out from particle to particle. 
The distribution of the energy among the particles starts from center and it will carry out outward. This disturbance will occur horizontally.
Therefore, the energy travels horizontally.
