As stars get older they get cooler and you know when you light a flame the part at the bottom is hotter so its also applies to stars, the star is very hot because it is newer and has more gas so it appears blue to us
Answer:
C. 2π cm
Explanation:
Measure of the length of arc(QR) = θ/360 × 2πr
Where,
θ = 60°
r = 6 cm
Plug in the values
Measure of the length of arc(QR) = 60/360 × 2 × π × 6
= 1/6 × 12 × π
= 2 × π
= 2π cm

Those big blocks
of folded land underneath the Earth’s surface are called Tectonic Plates. When

which we call Earthquakes. Earthquakes happen all the time but some are so weak
that they cannot be felt by people on the surface.
