Question

Answer the 2 one question and the 3 one beg you

Answer 1

Answer:

Physics

Explanation:

★ Question 1

» Unit of Force is NEWTON .

[ Option D ]

★ Question 2

Velocity is uniform ; so acceleration should be zero .

and we know that ; Force = Mass × Acceleration

so ; Force also zero .

[ Option D ]

★ Question 3

By momentum Conservation

★ M1 V1 = M2 V2 ★

- M1 = mass of bullet

- M2 = mass of Block and bullet

- V1 = velocity of bullet

- V2 = velocity of system

____________________________________________

V2 = M1 × V1 / M2 = ( 10 × 10-³ × 100 ) / ( 1 + 0.01 ) = 1 m / s

[ Option A ]
