Aleksandr [31]

Answer:

Oblique surface

Explanation:

Surfaces or lines situated at an angle in relation to all the main projection planes are oblique. An oblique surface never appears in any of the main perspectives as a line or true size area. It's Tipped to all main projection planes. doesn't quite appear on the edge of every standard view. doesn't quite show up in any view in true size.it has always been foreshortened.

Answer:

R/l = 0.25925 Ω / m

Explanation:

Ohm's law says that the potential difference is proportional to the product of the resistance by the current

         V = I R

         R = V / I

In this case, since we have two lengths, we can have two lengths, we can find the resistance for each

         L = 5 m

         R = 7.70 / 5.47

         R = 1,408 Ω

         L = 10 m

         R = 7.70 / 3.25

         R = 2,369 Ω

We can make a direct proportions rule (rule of three) to find the resistance per unit length

For L = 5 m

         R/l = 1,408 / 5

         R/l = 0.2816 Ω / m

For L = 10 m

        R/l = 2,369/10

        R/l = 0.2369 Ω / m

We can see that the value is similar that differs from the second decimal place, in this case the value for the longer re wire is more accurate because it has a lower joule effect.

One way also to find the average value

       R/l = (0.2816 + 0.2369) / 2

       R/l = 0.25925 Ω / m

Is position a base or derived quantity?
amid [387]

Position is measured in meters (m), so it is a base quantity.

<h3>What is base quantity?</h3>

A base or fundamental  quantity is a physical quantity, in which other quantities are derived from.

Example of fundamental quantities;

  • Mass
  • Length (position)
  • Time
  • Temperature
  • Amount of substance

<h3>What is a derived quantity?</h3>

Derived quantities are those quantities obtained or expressed from fundamental quantities.

Example of derived quantities;

  • Speed
  • Acceleration
  • Volume
  • Area
  • Density, etc

Thus, we can conclude that position measured in meters (m) is a base quantity.
