Scientific form = 6.5 x 109.
You have to do the math of each and see which one adds up to 66.5
Answer:
22.2 W
Explanation:
First of all, we calculate the work done by moving the wagon, using the formula:
where
F = 20 N is the magnitude of the force
d = 1000 m is the displacement of the wagon
is the angle between the direction of the force and of the displacement (assuming the force is applied in the direction of motion)
Substituting, we find
Now we can find the power generated, which is equal to the ratio between the work done and the time taken:
where
W = 20,000 J
t = 15 min = 900 s
Substituting,
And the same value in Joules/second (remember that 1 Watt = 1 Joule/second)
<h2>
Mercury, Neptune, and Jupiter </h2>
Explanation:
- Mercury has the largest semimajor axis that is 5.791 x 107 in km.
- Mercury is the planet with the fastest speed, which has an average orbital speed around the sun for about 47.87 km/s.
- Neptune has the longest orbital speed around the sun of any planet in the Solar System which is equivalent to 164.8 years (or 60,182 Earth days)
- Jupiter has the largest eccentricity.
Hence, the answer is Mercury, Neptune, and Jupiter respectively.
