Question

An unfilled electron state in the valence band of a semiconductor is called an empty positron. An empty electron a positron a conduction electron. Convex spherical mirrors produce images which could be larger than or the same size as the actual object, depending on the placement of the object. Could be smaller than or the same size as the actual object, depending on the placement of the object. Are always smaller than the actual object. Are always the same size as the actual object. Are always larger than the actual object. Scandium, ^43_21 Ca^43_21 Sc^45_21 Sc^44_20 Sc^44_20 Ca A spaceship approaches the earth with a speed 0.50c. A passenger in the spaceship measures his heartbeat as 70 beats per minute. What is his heartbeat rate according to an observer that is at rest relative to the earth? 61 beats per minute 65 beats per minute 69 beats per minute 80 beats per minute 73 beats per minute With respect to the earth object 1 is moving at speed 0.80c to the right. Object 2 is moving in the same direction at speed 0.80 degree C with respect to object 1. How fast is object 2 moving with respect to the earth? 0.80 C 1.6 C 0.98 c 0.64 C 0.0c Coherent light passes through four identical shits to produce a diffraction pattern on a distant screen. At a point P on the screen, the phase difference between light from the first and the last slits is 2 pi. Which of the phasor diagram below best describes this situation? (V) (IV) (II) (III) (I) If the ground state energy level of a proton in a rigid 1D box is 5.0 MeV, what is the width of the box. 2.7 times 10^-13 m 2.7 times 10^-15 m 6.4 times 10^-14 m 6.4 times 10^-13 m 6.4 times 10^-15 m

Explanation / Answer

8. e Unfilled electron state in a semiconductor is called a hole.

9. c The image produced by convex lens is always smaller in size as compared to the actual object.

10. c Positronium can be represented as 10e . Hence when it is added to the given nuclei, it results in the 'c' nuclei.

11. e 73 bpm
