What is the angle (in milliradians) subtended by the final telescopic image of Neptune? A) 1.3 mrad B) 0.90 mrad C) 1.5 mrad D) 1.7 mrad E) 1.1 mrad
You are standing on a platform and a train approaches you, moving at a constant velocity. Its whistle is blowing continuously. The train does not stop at the platform, but it continues to move past the platform at a constant velocity. Which of the following statements are true about the frequency of the train's whistle that you hear?
1.The whistle's frequency that you hear increases continually as the train approaches the platform and then decreases continually after the train passes the platform. 2.The whistle's frequency that you hear seems to you to remain constant for the entire duration of the train's passage. 3.The whistle's frequency that you hear decreases continually as the train approaches the platform and then increases continually after the train passes the platform. 4.The whistle's frequency that you hear remains constant as the train approaches the platform and then decreases immediately after the train passes the platform, after which it remains constant at a lower pitch than it had originally.
Given that the total number of atoms on our planet remains fairly constant, how is it ever possible to deplete a natural resource such as a metal?
A) The problem remains that not everyone recycles as they should. B) Recycling only forestalls the inevitable depletion of metal resources. C) The atoms don't leave our planet, which is why naturally occurring materials never really reach the point of depletion. D) The problem is with the expense of collecting metal atoms that are uniformly dispersed.
A 1.15-kg beaker (including its contents) is placed on a vertical spring scale. When the system is sent into vertical vibrations,
it obeys the equation y = (2.3 cm)cos(17.4 s-1 t). What is the spring constant of the spring scale, assuming it to be ideal?
