Explanation:
Both spoons are at the same temperature. However, metal is a good conductor of heat. When you touch it, it rapidly conducts heat away from your hand, making your skin feel a sudden drop in temperature (which you perceive as 'cold'). Wood is a poor conductor, so it draws heat from your hand very slowly.
One Parsec is a unit of astronomical distance. It is defined as the distance at which a radius of one astronomical unit (AU) subtends an angle of one second of arc. One parsec is approximately equal to:
Explanation:
The parsec (parallax second) is the largest standard unit of distance used in astronomy. 1 Astronomical Unit (AU) is approx 1.5 x 10^11 m. 1 Light Year (ly) is approx 9.46 x 10^15 m. 1 Parsec is approximately 3.08 x 10^16 m. Converting parsecs to light years: (3.08 x 10^16) / (9.46 x 10^15) ≈ 3.26 light years.
