The motorist is traveling at 65 miles per hour
Answer:
W = 1493.9 J = 1.49 KJ
Explanation:
The work done by the elevator on the object will be equal to the gain in is potential energy:
W = ΔP.E
W = mgΔh
where,
W = Work = ?
m = mass of object = 7.4 kg
g = 9.8 m/s²
Δh = gain in height = 20.6 m
Therefore,
W = (7.4 kg)(9.8 m/s²)(20.6 m)
<u>W = 1493.9 J = 1.49 KJ</u>
Density of Earth: 5.514 g/cm³
Density of Jupiter: <span>1.326 g/cm³
1.326 g/cm³ / 5.514 g/cm³ </span>≈ <span>0,24
0,24 * 100 = 24%
Jupiter has 24% of earth's density.
(Density numbers are from internet, you may calculate with your own ones if u have )</span>
