An iPod uses a standard 1.7 volt battery. How much resistance is in the circuit if it uses a current of

weeeeeb [17]

Answer:

R = 56.6 ohms

Step-by-step explanation:

Given that,

The voltage of the battery, V = 1.7 volt

We need to find the resistance in the circuit if it uses a current of 0.03 A.

Let the resistance be R. It can be solved using Ohms law as follows :

V = IR

$R=\dfrac{V}{I}\\\\R=\dfrac{1.7}{0.03}\\R=56.6\ \Omega$

So, the resistance in the circuit is 56.6 ohms.

Answer:

see explanation

Step-by-step explanation:

A column vector has the form $\left[\begin{array}{ccc}x\\y\\\end{array}\right]$

Following the direction of the arrow , the x- displacement = - 3 and y- displacement = 2 , then column vector is

$\left[\begin{array}{ccc}-3\\2\\\end{array}\right]$

h + k

= $\left[\begin{array}{ccc}4\\-3\\\end{array}\right]$ + $\left[\begin{array}{ccc}-2\\-1\\\end{array}\right]$ ← add corresponding elements from each vector

= $\left[\begin{array}{ccc}4-2\\-3-1\\\end{array}\right]$

= $\left[\begin{array}{ccc}2\\-4\\\end{array}\right]$
