The blackness of silver coin is due to the formation of silver sulphide on its surface due to its exposure to air. On boiling, the aluminium foil reacts with the...
When two coins are tossed simultaneously, the possible outcomes are(H, H),(H, T),(T, H),(T, T) which are all equally likely. Here (H, H) means head up on the first coin (say on Rs.1) and...
The outcomes associated with this experiment are given by
HHH, HHT, HTH, THH, TTH, THT, HTT, TTT
Total number of possible outcomes = 8
Now, Hanif will lose the game if he gets
HHT,...
(c) : In vertical simple harmonic motion, maximum acceleration (aω2) and so the maximum force (maω2) will be at extreme positions. At highest position, force will be towards mean position...
The correct answer is (d) = v.
EXPLANATION:
Since the source and the observer both move with the same speed there is no relative motion. Thus there is no Doppler's effect and...
