When you fly in an airplane at night in smooth air, you have no sensation of motion, even though the plane may be moving at 800 km/h 1500 mi/h2. Why?
Consider an electron entering a CRT area of deflation (2.3cm long) with a speed of 9.6 x 10^8
cm/s and a constant acceleration of 9.4 x 10^6 cm/s². The speed of the electron vertically
traveling is
2.25x 10^8 cm/s
1.35x 10^8 cm/s
3.75x 10^8 cm/s
8.75x 10^8 cm/s
None of the choices
If A = (6 m)i - (8 m) ĵ then 47 has magnitude:
O 10 m
O 56 m
O 40 m
0-8 m
08 m
