Answer:
Answer is given below:
Explanation:
<em>Given Data:</em>
mass = 80kg
acceleration = 4 ms
force = 800N
<em>Find out:</em>
friction = ?
<em>Formula</em><em>:</em>
F-friction = weight - f-net
<em>Solution:</em>
weight = (80)(10)
= 800 N
F-net = ma =(80)(4) = 320N
F-friction = weight - F-net
=800 N - 320N
=480N
<em>Answer</em> :
Friction = 480 N
Valence electrons in their outer shell
Answer:
C: Good conductors of electricity
Explanation:
By definition, Metals have metallic bonds and thus they are good conductors of electricity due to the fact that their electrons in the electron sea are usually free to flow and carry electric current. Thus, the correct answer is option C.
