Mira is much bigger than the Sun.
Only very massive stars will go through a supernova stage, causing the outer layer to explode away and the core to collapse in on itself, becoming very dense.
The approximate speed of sound in dry (0% humidity) air, in meters per second, at temperatures near 0 °C, can be calculated from

Here
Temperature in Celsius
Replacing with our values we have that



Therefore the speed of sound in air at that temperature is 366.1m/s
the answer is a because they start on the north side
R=U/I so
U=RxI
U= 10 x 42
U= 420 volts
Answer:
Ang answer units of J heat of fusion is 3.33 x 105
