C. copper
Explanation:
Copper is the best conductor of heat from the given options. Plastic, wood and cotton are all poor conductors other wise known as insulators.
Metals are typically good conductors of heat.
- they generally do not have a high specific heat capacity which implies that they get heated easily.
- a good conductor allows heat to flow fast and it simultaneously loses heat readily too.
- copper is a good conductor, when heat its perfectly allows heat to pass through
- when heat is removed, it loses it very fast.

Sunny watched a video of her professor’s lecture on genes and environment the
night before class and her professor facilitated a discussion about the role of
nature and nurture with respect to development, Sunny is experiencing being
advanced in their lesson. Nurture plays an important part in this. The
environment poses an encouraging and stimulating atmosphere where Sunny might
enjoy learning about things.
Answer:
Explanation:
The question relates to time of flight of a projectile .
Time of flight = 2 u sinθ / g
u is speed of projectile , θ is angle of projectile
= 2 x 48.5 sin42 / 9.8
= 6.6 seconds .
Maximum height attained
= u² sin²θ / g
= 48.5² sin²42 / 9.8
= 107.47 m .
Answer:
Explanation:
Given:
- mass of rocket,
- time of observation,
- mass lost by the rocket by expulsion of air,
- velocity of air,
<u>Now the momentum of air will be equal to the momentum of rocket in the opposite direction: </u>(Using the theory of elastic collision)
