Answer:
Time = 2758.62 seconds
Explanation:
Given the following data;
Speed = 290 m/s
Distance = 800 km to meters = 800 * 1000 = 800000
To find the time;
Time = distance/speed
Time = 800000/290
Time = 2758.62 seconds
Therefore, it will take the pilot 2758.62 seconds to reach the airport.
Answer:
C. stronger than
Explanation:
As Jupiter is 317 times massive than the Earth, its gravitational attraction would be stronger. This is because gravitational attraction force depends on mass and distance. At the same different, massive body will exert greater gravitational pull.
Thus, option c is correct.

Explanation:
From the question we are said that
The mass of the shed is
The pulling force is
The angle is
The distance covered is
The kinetic force is
Generally the work done is mathematically represented as
=>
=>
Generally according to the work-energy theorem
Here is total work done which is mathematically represented as
=>
=>
Also is the change in kinetic energy which is mathematically represented as
Here u is the initial velocity of the shed when at rest
=>
So
=>
=>
