Answer:
Explanation:
24 - gauge wire , diameter = .51 mm .
Resistivity of copper ρ = 1.72 x 10⁻⁸ ohm-m
R = ρ l / s
1.72x 10⁻⁸ / [3.14 x( .51/2)² x 10⁻⁶ ]
= 8.42 x 10⁻² ohm
= .084 ohm
B ) Current required through this wire
= 12 / .084 A
= 142.85 A
C )
Let required length be l
resistance = .084 l
2 = 12 / .084 l
l = 12 / (2 x .084)
= 71.42 m
<h2><u>Question</u><u>:</u><u>-</u></h2>
Ryan applied a force of 10N and moved a book 30 cm in the direction of the force. How much was the work done by Ryan?
<h2><u>Answer:</u><u>-</u></h2>
<h3>Given,</h3>
=> Force applied by Ryan = 10N
=> Distance covered by the book after applying force = 30 cm
<h3>And,</h3>
30 cm = 0.3 m (distance)
<h3>So,</h3>
=> Work done = Force × Distance
=> 10 × 0.3
=> 3 Joules
![\small \boxed{work \: done \: by \: Ryan \: = 3 \: Joules}](https://tex.z-dn.net/?f=%20%5Csmall%20%5Cboxed%7Bwork%20%5C%3A%20done%20%5C%3A%20%20by%20%5C%3A%20Ryan%20%5C%3A%20%20%3D%203%20%5C%3A%20Joules%7D)

Answer:
is b and d hope id helpful
Explanation:
idk how to explain
Temperature doesn't really affect solubility on liquids so it can only be D besides it's already a liquid....
