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.

mamaluj [8]

ANSWER:

(a) 1036 N

(b) -1036 N

(c) 2590 N

STEP-BY-STEP EXPLANATION:

Given:

Mc = 1400 kg

Mt = 560 kg

a = 1.85 m/s^2

(a)

Force by car on trailer:

\begin{gathered} F_c=m\cdot a \\ F_c=560\cdot1.85 \\ F_c=1036\text{ N} \end{gathered}

(b)

\begin{gathered} F_t=-F_c \\ F_t=-1036\text{ N} \end{gathered}

(c)

\begin{gathered} F_n=1400\cdot1.85 \\ F_n=2590\text{ N} \end{gathered}
