Answer: Option D

57. the unit of angular acceleration is

- rad/s2

[A]. Doubled                          [B]. Half

[C]. One-fourth                       [D]. One-fourth

Answer. A. Doubled

59. What quantity of charge must be delivered by a battery with a Potential Difference of 110 V to

do 660J of Work?

A. 0.6 C                         B. 6 C

C.60 C                           D.  600 C

Answer: B. 6C

Explanation: Q = W / V = 660J / 110V = 6C

60. In case of Short Circuit ______Current will flow in the Circuit.

A. Zero                                B.  Very Low

C. Normal                           D.  Infinite

Answer: D. Infinite


At the short circuited point, the voltage difference is very low (about Zero) So then put the value in

I = P/V, so if we put V = 0, Then Current will be infinite.

61. A simply supported beam of span L carries a concentrated load W at its mid-span. The maximum

bending moment M is

- WL/4

62. The unit of moment of inertia of an area is

- mm4

63. which of the following is a vector quantity

A. Linear displacement                          B. Linear velocity

C. Linear acceleration                            D. All of these

Answer: Option D

64. The method of measuring distance by pacing is chiefly used in

[A]. reconnaissance surveys                 [B]. preliminary surveys

[C]. location surveys                            [D]. all of these

Answer: Option A

65. The height of a water column equivalent to a pressure of 0.15 MPa is

[A]. 15.3 m                            [B]. 25.3 m

[C]. 35.3 m                            [D]. 45.3 m

Answer: Option A


p = H*W.

p = 0.15 * 10^6 pa,

w = specific weight of water = 9810 N/m3.

i.e., H = (0.15 * 10^6)/(9810) = 15.3 m.

[C]. horizontal angle                           [D]. deflection angle

Answer: Option B

70. The horizontal angle between the true meridian and a survey line is called

[A]. magnetic bearing                           [B]. azimuth
