Answer: 3.2 * 10^-3 C
Explanation: In order to solve this problem we have to use the Coulomb force given by:
F=k*q^2/ d^2 where he consider the same charge for each point
so, we have
q^2= F*d^2/k= 1.137* (10 C*9*10m)^2/9*10^9 N*m^2/C^2)=3.2 * 10^-3 C.
Answer:
10×2=20
10×2÷64=??
I am not sure what you are trying to say...
She recoil at a high speed than a low
if there were no invention of machines then life would have been more difficult and simple works could be hard to do. Even now we are using our phones, sitting in a AC room interacting to eachother from different places. without the invention of machines simple things like transportation would have been difficult. There would be horses and donkey for the transportation. There would be no electricity,no internet, no transportation, not even c computers or mobile etc. The market for business will be smaller, the knowledge and news about world would be less.
so the problem would have been bigger than we can imagine. But one thing is that nature could survive lot more compared to what we have done till now by destroying nature.
