One carat is equal to 200 milligrams, or 0.2 grams.
3
4.2 kWh = ?
RRB Group D
2018
✓ Answer:B15.12 × 10⁶ J
4.2 × 3.6 × 10⁶ J = 15.12 × 10⁶ J.
4
10⁻⁹ meter is equal to ______ Angstrom.
RRB RPF Constable
2025
✓ Answer:A10
1 Å = 10⁻¹⁰ m, so 10 Å = 10⁻⁹ m.
5
1 Nano meter = ?
RRB Group D
2018
✓ Answer:B1/10⁹ m
1 nanometre = 10⁻⁹ m, which is 1/10⁹ m.
6
1 kilowatt is equal to ______.
RRB Group D / RRB Technicians Grade-III
2018 / 2024
✓ Answer:C1000 J s⁻¹
1 kW = 1000 W and 1 W = 1 J/s, so 1 kW = 1000 J s⁻¹.
7
1 coulomb/1s = ?
RRB Group D
2018
✓ Answer:B1 ampere
Electric current is charge per unit time: 1 A = 1 C/s.
8
One erg is equal to ______.
RRB RPF SI
2024
✓ Answer:D10⁻⁷ J
In the CGS system, 1 erg = 10⁻⁷ joule.
9
1 Pico meter = ?
RRB Group D
2018
✓ Answer:C10⁻¹² m
The SI prefix pico denotes 10⁻¹², so 1 pm = 10⁻¹² m.
10
1 atmosphere = ?
RRB Group D
2018
✓ Answer:A1.01 × 10⁵ Pa
Standard atmospheric pressure is 101325 Pa, approximately 1.01325 × 10⁵ Pa.
