In the book,the distance between two planets is given as 4.07×10^¹² kilometres. The speed of light is 1.1×10^⁹ kilometres per ho

Sphinxa [80]

Answer:

3700hours

154days

Step-by-step explanation:

Speed can be defined as the distance cover per time, it can be expressed as

Speed= distance/ time........eqn(1)

Given:

distance between two planets= 4.07×10^¹²

speed of light = 1.1×10^⁹ kilometres per hour

Time= ??

Then substitute the values into equation (1) we have

Speed= distance/ time

1.1×10^⁹ kilometres per hour= 4.07×10^¹²kilometre/ time

Cross multiply, we have

Time= (4.07×10^¹²kilometre) /(1.1×10^⁹ kilometres per hour)

Time= 3700hours.

To convert to day, we know that

60 minute= 1hour

24hour=1day

Time= (3700hour×1day)/24hour

Time= 154days approximately.

Hence, the time taken for light to travel from one of these planets to the other is 154days or 3700hours

Write the ordered pair that represents mp. Then find the magnitude of mp.<br> M(2, -1), P(-3, 4)

Sonja [21]

The magnitude of ordered pair MP is 7.07, If the given points are M (2,-1) and P (-3, 4).

Step-by-step explanation:

The given is,

The ordered pair that represents MP

M (2, -1)

P (-3, 4)

Step:1

Distance formula can be used to calculate the magnitude,

Formula to calculate magnitude of point MP is,

$Magnitude = \sqrt{(x_{2}-x_{1})^{2}+(y_{2} -y_{1} )^{2} }$ ................(1)

Where, $(x_{1}, x_{2} )$ and $(y_{1}, y_{2} )$ are points

From the given values,

M (2, -1) - $(x_{1}, y_{1} )$

P (-3,4) - $(x_{2}, y_{2} )$

Equation (1) becomes,

$Magnitude of MP = \sqrt{(-3-2)^{2}+(4 +1 )^{2} }$

$= \sqrt{(-5)^{2}+(5 )^{2} }$

$= \sqrt{25+25}$

$= \sqrt{50}$

= 7.07106 ≅ 7.07

Magnitude of MP = 7.07

Result:

The magnitude of ordered pair MP is 7.07, If the given points are M (2,-1) and P (-3, 4).
