Drag;
Drag is the aerodynamic force that opposes an aircraft's motion through the air. Drag is generated by every part of the airplane (even the engines!). How is drag generated? Drag is a mechanical force. It is generated by the interaction and contact of a solid body with a fluid (liquid or gas).
The drag on an object depends on several variables. The most important of them, to understand the experiments you carried out is the area of the object.
The area of the object is the most important factor to understand the experiments.

Answer:
F = 45 KN = 45000 N
Explanation:
Considering the downward direction as the positive direction:
where,
P = Resultant Pressure = ?
P₁ = Atmospheric Pressure = 100 KPa
P₂ = Pressure inside the can = 70000 Pa = 70 KPa
Therefore,
Now the resultant force will be given as:
where,
F = resultant force = ?
A = Area of side of can = 1.5 m²
Therefore,
<u>F = 45 KN</u>
Answer:
Explanation:
Given the following data;
Distance = 46 km
Time = 11 minutes
To find the average speed;
Speed = distance/time
