Consider the three dip1acement vectors A = (3i - 3j) m, B = (i-4j) m, and C = (-2i + 5j) m. Use the component method to determin
tia_tia [17]

Answer with Explanation:

We are given that

A=3i-3j m

B=i-4 j m

C=-2i+5j m

a.D=A+B+C

D=3i-3j+i-4j-2i+5j

D=2i-2j

Compare with the vector r=xi+yj

We get x=2 and y=-2

Magnitude=\mid D\mid=\sqrt{x^2+y^2}=\sqrt{(2)^2+(-2)^2}=2\sqrt 2 units

By using the formula \mid r\mid=\sqrt{x^2+y^2}

Direction:\theta=tan^{-1}\frac{y}{x}

By using the formula

Direction of D:\theta=tan^{-1}(\frac{-2}{2})=tan^{-1}(-1)=tan^{-1}(-tan45^{\circ})=-45^{\circ}

b.E=-A-B+C

E=-3i+3j-i+4j-2i+5j

E=-6i+12j

\mid E\mid=\sqrt{(-6)^2+(12)^2}=13.4units

Direction of E=\theta=tan^{-1}(\frac{12}{-6}=tan^{-1}(-2)=-63.4^{\circ}

The graph below shows the energy sources used to generate electricity in the United States.
DedPeter [7]

The correct answer is - D. 1 percent.

The United States are the biggest consumer of electricity in the world. Because of that the United States are using multiple different sources in order to satisfy the demand for the electricity. The solar energy though accounts for only 1% of the total amount of produced electricity in the country and that is concerning. The biggest concern of course is the environmental one as the majority of the electricity is produced by sources that are polluting the environment. The other concern is that the United States are not using their potential in gaining more electricity from the solar radiation when taken in account that they have very large areas in the country that have a lot of intense solar radiation and clear skies throughout most of the year.

Complete the calculations for total magnification produced by various combinations of the eyepiece and objective lenses. You may
lesya692 [45]

Answer:

a) m_ttoal = 40x , b)     m_total = 100X , c) m_total = 400X ,

d)     m_total = 1000 X

Explanation:

La magnificación o aumentos es el incremento de del tamaño de la imagen con respecto al tamaño original del objeto, en la mayoria del os sistema optico la magnificacion total es  el producoto de la magnificación del objetivo por la magnificación del ocular

       

    m_total = m_ objetivo  * m=ocular

apliquemos esto a nuestro caso

1)  m_total = 4 x * 10 x

    m_ttoal = 40x

2)  m_total = 10X * 10X

    m_total = 100X

3)mtotal = 40X * 10X

     m_total = 400X

4) m _totla = 100x * 10 X

     m_total = 1000 X

en este ultimo caso para magnificación grandes es decalcificar el objeto
