Forget the numbers and think about how speed works for a second. If a plane flies at 600km/h, this means that it will fly exactly 600 km in 1 hour. So, how long would it take to fly 2400 km??
2400/600 = 4hours.
Do this for all three and add up the hours.
Total time: 12 hours
Average speed is the total distance / total time.
So,
Add up all the distances and divide by 12.
(2400+1200+2500) / 12
Average speed: 508.33333333 km/h
First we need to find the voltage difference between the initial and final location of the electron.
Since the electron travelled for a distance d=5 m in an uniform electric field of intensity E=300 N/C, the voltage difference between the final and initial location is
And then, we can calculate the change in potential energy of the electron, which is the product between the charge of the electron and the voltage difference:
And the negative sign is due to the fact that we assumed the electron traveled in the natural direction of the electric field, so traveling from a point at lower voltage to a point at higher voltage (the sign of
is positive), so since it's a negative charge the electron is losing potential energy.
Answer:
The sun produces energy by Nuclear Fusion.
Explanation:
Turns Hydrogen atoms to Helium which is then known as Nuclear Fusion.
