Vadim26 [7]

Answer : The question is incomplete, the complete question is attached in answer

To calculate the displacement by Ann's driving from north of her house to south;

we have the data as

In north - 10 km
in south - 5 km
total - 15 km

So we can calculate the displacement, which will be,

10 - 5 = 5 km.

Hence, the displacement will be 5 km

This is pseudoscience, because:
1) The researchers were so excited to report that they had discovered a fuel that burns so hot that it becomes cold. - This would have to be proven again. It may not be this that caused the explosion.
2) Much to the relief of the original team or researchers, no other scientist could ever replicate their find. - It can't be replicated, so once again, it proves that it may not be that the fuel burns so hot it becomes cold
3)The researchers quickly wrote up a report, created a press release, and applied for a patent. - The report can have errors if it had been 'quickly' written. Also, because it could not be replicated, there is no need for a patent, as it could not be 'proven' again

hope this helps
