Answer:

<u>c. I = 1.73A</u>

Explanation:

The formula for power :

  • P = VI

The formula for potential difference :

  • V = IR

Calculating P by inputting the formula of V :

  • P = (IR)(I)
  • P = I²R

Solving using the given values :

  • 18 = I² x 6
  • I² = 3
  • I = √3
  • <u>I = 1.73A</u>

We need voltage first

  • P=V²/R
  • V²=PR
  • V²=18(6)
  • V²=108
  • V=√108
  • V=10.4V

Apply oHMS law

  • V/I=R
  • I=V/R
  • I=10.4/6
  • I=1.73A

Basalt, formed from magma, contains iron-rich minerals. Why is this important?
Svetach [21]
Iron is a magnetic metal, and it is essential to the Earth's magnetic field!
Essentially it "records" (stores the information, maintains) the direction and orientation of the magnetic field.

Among others, the magnetic field protects the Earth from dangerous cosmic rays.

A small airplane takes on 302 l of fuel. If the density of the fuel is 0.821 g/ml, what mass of fuel has the airplane taken on?
ella [17]

To calculate the mass of the fuel, we use the formula

m = V \times  \rho

Here, m is the mass of fuel, V is the volume of the fuel and its value is V =302 \ L =  302 \ L \times \frac{10^{3}m L }{L} = 302 \times 10^{3} \ mL and  \rho is the density and its value of  0.821 g/mL.

Substituting these values in above relation, we get  

m = 302 \times 10^{3} \ mL \times 0.821 g/mL = 247942 g \\\\ m = 247. 94 \ kg

Thus, the mass of the fuel 247 .94 kg.

The x vector component of a displacement vector has a magnitude of 86.2 m and points along the negative x axis. The y vector com
Flauer [41]

Answer:

(a) Magnitude of Vector = 207.73 m

(b) Direction = 65.48°

Explanation:

(a)

The formula to find out the magnitude of a resultant vector with the help of its x and y components is given as follows:

Magnitude\ of\ Vector = \sqrt{d_{x}^{2} + d_{y}^{2}} = \sqrt{(86.2\ m)^{2} + (189\ m)^{2}}\\\\

<u>Magnitude of Vector = 207.73 m</u>

(b)

For the direction of the vector we have the formula:

Direction = tan^{-1}(\frac{y}{x})\\\\Direction = tan^{-1}(\frac{189\ m}{86.2\ m})\\\\

<u>Direction = 65.48°</u>
