Answer:
Move towards the wall.
Explanation:
When the balloon is kept near to the wall not touching the wall, there is a force of electrostatic attraction so that the balloon moves towards the wall and stick to it.
As there is some charge on the balloon and the wall is uncharged so the force is there due to which the balloon moves towards the wall.
<h2>
Speed of jet is 730 miles per hour and speed of wind is 160 miles per hour.</h2>
Explanation:
Let the speed of jet be j and speed of wind be w.
Flying against the wind a jet travels 1710 miles in 3 hours
Distance = 1710 miles
Time = 3 hours
We have
Distance = Speed x Time
1710 = Speed x 3
j - w = 570 miles per hour ----------------eqn 1
Flying with the wind the same jet travels 6230 miles in 7 hours
Distance = 6230 miles
Time = 7 hours
We have
Distance = Speed x Time
6230 = Speed x 7
j + w = 890 miles per hour ----------------eqn 2
eqn 1 + eqn 2
2 j = 1460
j = 730 mph
Substituting in eqn 2
730 + w = 890
w = 160 mph
Speed of jet is 730 miles per hour and speed of wind is 160 miles per hour.
