Science (Physics) Questions For CTET Exam: 22nd May 2019 (Solutions)_80.1
Solutions:
S1. Ans.(d) 
Sol. 
Pressure, P= F/A; P’ = F/A/2 = 2F/A; P’ = 2P 
S2. Ans.(b) 
Sol. 
When a simple pendulum immersed in water then its oscillations are damped and its wave is cosine wave. 
S3. Ans.(b)
Sol. 
S4. Ans.(c) 
Sol. 
As the body moves with a constant speed v along a straight line or rectilinear path hence body undergoes a uniform velocity. Here direction of the moving body is unchanged. 
S5. Ans  (a)  
Sol. If the train were moving with uniform velocity, the coin would fall back to the passenger’s hand. While, if the train is accelerated, the horizontal velocity of the train would be more than that of the coin by the time the coin returns. Therefore, the train travels a greater horizontal distance than the coin and coin falls behind the passenger.
