Answer:
(D) Vf² = Vi² + 2ad
a = 2.269 m/s²
Explanation:
Given;
final velocity of the aircraft, Vf = 33 m/s
initial velocity of the aircraft, Vi = 0
distance traveled by the plane, d = 240 m
The acceleration of the plane is given by the following kinematic equation;
Vf² = Vi² + 2ad
where;
a is the acceleration;
Based on the given options, the correct option is "D".
Calculating the acceleration with the chosen equation;
Vf² = Vi² + 2ad
Vf² = 0+ 2ad
Vf² = 2ad
a = Vf² / 2d
a = (33)² / (2 x 240)
a = 2.269 m/s²
Pressure is the force acting per unit area and increases with increase in the weight of a body.
<h3>What is pressure?</h3>
Pressure is defined as the force acting per unit area of a body.
Pressure depends upon the amount of force on an object and the size of the area the force pushes or pulls on.
The greater the amount of weight pressing on an object, the greater the amount of pressure.
Of the following objects air, ice, plastic, and gold, gold is the most dense.
A dense object will produce more pressure than one that is not dense since it exerts a greater force per unit area.
Solids exert pressure because gravity is pulling downward on the object.
It is not true that the human body has more pressure sensors in the legs than in the fingertips as pressure sensors are more in fingertips.
Therefore, pressure is the force acting per unit area and increases with increase in the weight of a body.

It could combine with any other metal on the periodic table. If I had answers to choose from, then maybe I could help you better.
Hope this helps!!!
Answer:
A first-class lever: fulcrum is between input and output force; second-class lever: output force is between input force and fulcrum; third-class lever: input force is between fulcrum and output force
