The unit for the solid angle is

A
degree

B
rad

C
Sr

D
none of these

Solution

The unit of solid angle is steradian (Sr). One steradian is equal to (180/π)² square degrees.
Question 2

Which of the following is not a unit of power?

A
Wh

B
kW

C
HP

D
N ms^-1

Solution

Watt-hour (Wh) is not a unit of power. Wh is the unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time.
Question 3
1 / -0

Which of the following is a fundamental quantity?

A
Volume

B
Velocity

C
Time

D
Force

Solution

The seven fundamental quantities are weight, length, time, current, temperature, number of particles, and luminous intensity. Out of the four options, time is a fundamental quantity.
Question 4
1 / -0

Which is the correct unit for measuring astronomical distance?

A
Mole

B
Light Year

C
Kilometer

D
Angstrom unit
Question 5
1 / -0

Convert 5^` (minute of arc) into radians.

A
1.455 × 10^-3 rad

B
2.91 × 10^-4 rad

C
2.85 × 10^-6 rad

D
5.84 × 10 ^-4 rad

Solution

We know that 1 radian = 3437.75 minutes of arc
1 minute of arc = 1 ÷ 3437.75 radians
= 2.9 x 10^-4 radians
5 minutes of arc = 14.5 x 10^-4 radians or 1.45 x 10^-3 radians
Question 6
1 / -0

Convert π/2 rad into degree.

A
180°

B
360°

C
90°

D
270°
Question 7
1 / -0

1 A° is equal to

C
10^–3m

D
10^–6 m
Question 8
1 / -0

One Light Year is equal to

A
9.46 ×10¹⁵ m

B

C
1.66 × 10²⁷ m

D
2.76 ×10⁴ m
Question 9
1 / -0

One kilometer is equal to

A
10³ mm

B
10⁶ mm

C
10⁹ mm

D
10¹² mm

Solution

1 km = 1000 m
= 1000 x 100 cm
= 1000 x 100 x 10 mm
= 10⁶ mm
Question 10
1 / -0

The density of water is

A
0.1 kgm^-3

B
10 kgm^-3

C
100 kgm^-3

D
1000 kgm^-3

Solution

The density of water is 1 g/cm³.
1 g = 10^-3 kg
1 cm³= 10^-6 m³
1 g/cm³ = 10^-3/10^-6 kg/m³ = 10³ kg/m³
