<h2>Answer:</h2>
<em>Metals are both good heat conductors and good electrical conductors because of the </em><em>looseness of outer electrons in metal atoms</em>
_________________________
Unlike nonmetals that are insulators, most metals are both good heat conductors and good electrical conductors. This is because within a solid metal there is one or more outer electrons in each atom that become detached and can move freely through the solid metal, but <em>what about the other electrons?</em> Well, the
y remain bound to the positively charged nuclei, and bound within the material in almost fixed positions. On the other hand, insulators are material having few, very few or no electrons that are allowed to move freely through the material.
Answer:
224236.76 W
Explanation:
Power: This can be defined as the rate of change of energy. The S.I unit of power is Watt(W).
From the question,
P = E/t ......................... Equation 1
Where P = power, E = Energy or work, t = time.
But,
E = Wt×d.................. Equation 2
Where Wt = Total weight of the passengers, d = distance.
Substitute equation 2 into equation 1
P = (Wt×d)/t.............. Equation 3
Given: Wt = 590×150 =88500 N, d = 244 m, t = 96.3 s.
Substitute into equation 3
P = (88500×244)/96.3
P = 224236.76 W
