In a hydraulic garage lift, the smallpiston has a radius of 5.0 cm and the large piston has a radius of15 cm. What force must be applied on the small piston in order tolift a car weighing 20,000 N on the large piston? a. 6.7 ×103 N
b. 5.0 ×103 N
c. 2.9 ×103 N
d. 2.2 ×103 N

Option  d) 2.2 × 10³ N is the correct answer

Explanation:

Given that;

radius of A₁ = 5.0

large piston has a radius of A₀ = 15 cm

Weight F₀ = 20,000 N

Force that must be applied to lift the weight F₁ = ?

Now we know that from Pascal Law

ΔP ⇒ F₁/A₁ = F₀/A₀

F₁ =  (F₀/A₀)A₁

where A = πr²

so we substitute

F₁ =  (20,000 / π(15²)) × π(5²)

= (20,000 / 706.8583) × 78.5398

= 2222.22 ≈ 2.2 × 10³ N

Therefore Option  d) 2.2 × 10³ N is the correct answer.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
