1
The mass density of an object is defined as its ______.
RRB ALP (Stage-II)
22/01/2019 / Shift-I
2019
✓ Answer:CMass per unit volume
Density is mass per unit volume: ρ = m/V.
2
During the free fall of an object, which of the following energies increases at a point in its path?
RRB Group D
19/09/2018 / Shift-II
2018
✓ Answer:BKinetic energy
As an object falls, gravitational potential energy is converted into kinetic energy.
3
What is the mass per unit volume of a substance called?
RRB JE; RRB Group D
30/08/2019 / Shift-I; 05/10/2018 / Shift-I
2019; 2018
✓ Answer:CDensity
Density is the mass per unit volume of a substance.
4
A block of mass 2 kg slides on a horizontal surface at 4 m/s and compresses a spring until it stops. The kinetic frictional force is 15 N and the spring constant is 10000 N/m. What is the compression of the spring?
RRB Group D
10/12/2018 / Shift-I
2018
✓ Answer:D5.5 cm
Using energy conservation, (1/2)mv² = (1/2)kx² + 15x. Thus 16 = 5000x² + 15x, giving x ≈ 0.0551 m = 5.5 cm. The source calculation omits friction but selects the same approximate answer.
5
What form of energy is not generated when riding a bicycle?
RRB ALP & Technician
10/08/2018 / Shift-I
2018
✓ Answer:AChemical energy
Riding uses stored chemical energy and converts it into mechanical energy and heat; chemical energy is not generated.
6
What is the value of 100 grams of mass in SI units?
Mass measures the amount of matter present in a substance.
9
Which statements are correct? 1. The mass of an object is equal to its weight. 2. The mass of an object is not equal to its weight. 3. Mass is a scalar quantity while weight is a vector quantity.
RRB ALP (Stage-I)
26/11/2024 / Shift-II
2024
✓ Answer:DStatements 2 and 3 are correct.
Mass and weight are different physical quantities. Mass is scalar; weight is the gravitational force and is a vector.
10
Which option is correct regarding mass and inertia?
