<span>If you can't measure the parallax that means that the star is far far away, beyond all possible reach of humanity with its current technology. The closer the star is the greater the parallax, so you either get a bigger, more powerful telescope, or you just accept that it's too far away to be measured at all. Eventually the technology will develop enough to measure it.</span>
Answer:
You don't have to take my word on this, but given that there is less wax on A after heating, it sent the most heat into the wax balls therefore it is a better conductor if heat
4.8 km because if u add the other bonus if speed and multiply you check the 48 taking off a decimal point
Because we can send high voltage, low current which is more efficient since large amounts of current in the line causes power inefficiencies. AC can be transformed locally to high current lower voltage
