3.3cm
6.5cm
7.5cm
10.8cm
15.0cm
Correct answer is C
F \(\alpha\) e and m \(\alpha\) F
\(\frac{m_1}{e_1}\) = \(\frac{m_2}{e_2}\)
\(\frac{10}{5}\) = \(\frac{15}{e_2}\)
e2 = 7.5cm

A hot metal ball is suspended in the open air. As it cools it loses heat by?
conduction only
convection only
radiation only
conduction and convection
convection and evaporation
Correct answer is B
Convection occurs when heat is carried away from your body via moving air. If the surrounding air is cooler, the air will absorb heat and rise.
As the warmed air rises, cooler air moves in to take its place and absorb more warmth.
