46.6666 that is the mass number

It takes 20347.4098071s for light from the sun to reach Pluto.
The 6.1*10^9 is replaced by 6.1*10^12 on line 4 because we convert the distance from km to m.
c = speed of light. If a different value was given in the previous question then use that instead of the value I used to do the final calculation.
It is fairly easy to build an electromagnet. All you need to do is wrap some insulated copper wire around an iron core. If you attach a battery to the wire, an electric current will begin to flow and the iron core will become magnetized. When the battery is disconnected, the iron core will lose its magnetism. Follow these steps.
Step 1 - Gather the Materials
One iron nail fifteen centimeters (6 in) long
Three meters (10 ft) of 22 gauge insulated, stranded copper wire
One or more D-cell batteries
Step 2 - Remove some Insulation
Step 3 - Wrap the Wire Around the Nail
Step 4 - Connect the Battery
Answer:a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.

Answer:
Distance traveled will be 
Explanation:
We have given speed of the light 
We have to find the distance traveled by light in 1 year
We know that 1 year = 8760 hour
And 1 hour = 60×60 = 3600 sec
So 1 year 
We know that distance = speed × time
So distance traveled by light in one year 
We have to fond the distance in km
As we know that 1 km = 1000 m
So
