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
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,
................(1)
Where,
and
are points
From the given values,
M (2, -1) - 
P (-3,4) - 
Equation (1) becomes,



= 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).
