If a truck weighs 18,000 N and it’s tires are inflated to a pressure of 190 kPa how large is the area of the trucks tires that a
1 answer:
0.095m²
Explanation:
Given parameters;
Weight of truck = 18000N
Pressure = 190kPa or 190000Pa
Unknown:
Area of truck tires = ?
Solution:
Pressure is given as the force per unit area of a substance:
Pressure =
Since Area is the unknown, we make it the subject of the expression;
Area =
=
= 0.095m²

This problem uses the relationships among current I, current density J, and drift speed vd. We are given the total of electrons that pass through the wire in t = 3s and the area A, so we use the following equation to to find vd, from J and the known electron density n, so:
<span>The current I is any motion of charge from one region to another, so this is given by:
</span>
The magnitude of the current density is:
Being:
<span>
Finally, for the drift velocity magnitude vd, we find:
</span>
Notice: The current I is very high for this wire. The given values of the variables are a little bit odd
