Question

I need help with the following three physics problems please!

Answer 1

None of these is a Physics problem. The numbers, and the fractions that
they appear in, might have come from Physics problems, but these are
nothing more than arithmetic exercises, and they can be whipped out
in a hurry with a little bit of fancy calculator work.  You don't have to
know any Physics in order to answer any of these. 

The first one is 2.7 x 10⁻²⁴ Newton.
