A rocket ejects gases backward and experiences an equal and opposite forward reaction.
37
The ______ of an object is fixed and does not change when it is moved to another place.
RRB Group D
20/09/2018 / Shift-III
2018
✓ Answer:BMass
The amount of matter, or mass, remains unchanged with location.
38

08/01/2021 / Shift-II; 26/10/2018 / Shift-II
2021; 2018
✓ Answer:CNewton
Sir Isaac Newton proposed the three laws of motion.
39
The momentum of a body is 50 kg·m/s and its velocity is 5 m/s. What is its mass?
RRB Ministerial & Isolated Categories (All PGTs and TGTs); RRB Group D
10/09/2025 / Shift-II; 29/10/2018 / Shift-III
2025; 2018
✓ Answer:D10 kg
p = mv, so m = p/v = 50/5 = 10 kg.
40
