Answer: orbit

Explanation:

Our sky is divided into 88 areas known as constellations. These constellations are identified by the brightest stars of these areas forming a recognizable pattern. As the Earth travels in its orbit around the Sun, different constellations are visible at different times of the year. This is because different part of the sky is visible as earth goes around the Sun.

Thus, As Earth travels in its<u> </u><u>orbit</u><u> </u>different constellations are visible at different times of the year.

What is the equivalent resistance in this circuit?<br><br> What is the current in this circuit?

kramer

All these resistors are in series so we can take the sum of them by:

Rtotal = R1 + R2 + R3......

So...

Rtotal = 2 + 3 + 4 + 6

Rtotal = 15

So now the total resistance in the circuit is 15 ohms and the potential difference applied to the circuit is 45 volts

Now we can use:

V = IR

Isolate for I

V/R = I

45/15 = I

I = 3 amps (A)

A wire 73.6 cm long carries a 0.720 A current in the positive direction of an x axis through a magnetic field with an x componen

Alex787 [66]

Answer:

(a)

0

(b)

- 0.0041

(c)

0.000143

Explanation:

$\underset{L}{\rightarrow}$ = length of the long wire = 73.6 cm = 0.736 $\hat{i}$ m

$\underset{B}{\rightarrow}$ = magnetic field = 0 $\hat{i}$ + 0.000270 $\hat{j}$ + 0.00770 $\hat{k}$

i = current in the wire = 0.720 A

Magnetic force is given as

$\underset{F}{\rightarrow}$ = i ( $\underset{L}{\rightarrow}$ x $\underset{B}{\rightarrow}$ )

Inserting the values

$\underset{F}{\rightarrow}$ = (0.720) ((0.736 $\hat{i}$ ) x (0 $\hat{i}$ + 0.000270 $\hat{j}$ + 0.00770 $\hat{k}$ ))

$\underset{F}{\rightarrow}$ = (0.720) (0 $\hat{i}$ - 0.0056672 $\hat{j}$ + 0.00019872 $\hat{k}$ )

$\underset{F}{\rightarrow}$ = 0 $\hat{i}$ - 0.0041 $\hat{j}$ + 0.000143 $\hat{k}$

(a)

x- component = 0

(b)

y-component = - 0.0041

(c)

z-component = 0.000143
