Answer:
The answer to your question is time = 1 s
Explanation:
Data
time = ?
Power = 700 W
Work = 700 J
Power is defined as the work done per unit of time.
Formula
Power = Work / Time
-Solve for time
Time = Work/Power
-Substitution
Time = 700 / 700
-Result
Time = 1 s
Conclusion
In 1 second and with 700 J there will be produced 700 watts
That's false. Convection is the process of moving heat around
by heating a fluid and letting the fluid flow to somewhere else.
There's no fluid in the space between the sun and us, so convection,
and conduction too, aren't possible. The only way for the sun's light,
heat, and X-ray energy to get here is by the process of RADIATION.
The answer is c) sink and fill in the space.

Distance travel = 400km
Time it took to travel 400km = 5 hr
Average speed = (distance travel)/(Time for that travel)
s = 400km/5h = 80km/hr
The average speed is 80km/hr.
