Question

Match the following :
Technology Scientific Principles
(a) Aeroplane 1. Newton's Law
(b) Air Balloon 2. Bernoulli's Principle
(c) Rocket 3. Law of thermodynamics
(d) Steam Engine 4. Buoyant Force
(a) (b) (c) (d)
(A) 1 3 2 4
(B) 3 1 4 2
(C) 4 2 3 1
(D) 2 4 1 3

Answer 1

hey here is your answer :-

➡ option

▶"D"◀

is the correct answer.

hope it helps u..♥☺♥

Answer 2

answer : option (D) 2 4 1 3

explanation : aeroplane works on Bernoulli's principle,

Buoyant force acts on air balloon,

rocket works on Newton's 3rd law,

steam engine works on law of thermodynamics.

so, from above explanation, we can match all the options easily.

(a) aeroplane <=> 2. Bernoulli's principle

(b) air balloon <=> 4. Buoyant force

(c) rocket <=> 1. Newton's law

(d) steam engine <=>3. law of thermodynamics

hence, answer is option (D)
