Answer:
Explanation:
If we express all of the cordinates in their rectangular form we get:
A = (1404.77 , 655.06) m
Since we need C to be (0,0) we stablish that:
That way we make an equation system from both X and Y coordinates:
Replacing values:
With this system we can solve for both Db and Dc and get the answers to the question:
Possibly something that interacts with the earth's magnetic field and produces the spectacular "Northern Lights", or "Aurora Borealis" if you prefer latin. Charged particles moving at relativistically high speeds, some of which may be from the sun via solar flares. I think that mu mesons are cosmic rays. First discovered by a scientist in a hot air balloon (he 'd gone up with instruments to detect them), and later used to verify the time dilation result of special relativity by MIT and the "mount washington experiment".
Answer:
The correct option is that both the ends will remain neutral.
Explanation:
As the rod is grounded all of the prolonged charge will be converted to ground so the overall charge on the rod in absence of the charged ball will be equal to zero.Such that the both ends will not bear any charge.
Answer:
Explanation:
The tension in a cable is given by:
Where 
is the mass density of the cable and v is the speed of the cable's pulse. These values are defined as:
The pulse makes four trips down and back along the cable, so 
Replacing (2) and (3) in (1), we calculate the tension in the cable:
