An electron moves with a constant horizontal velocity of 3.0 × 106 m/s, and no initial vertical velocity as it enters a deflector inside a TV tube
The electron strikes the screen after traveling 17.0 cm. horizontally and 40.0 cm vertically upward with no horizontal acceleration. What is the constant vertical acceleration provided by the deflector? (The effects of gravity can be ignored.)
A) 2.5 × 1014 m/s2
B) 8.3 × 102 m/s2
C) 1.4 × 104 m/s2
D) 1.2 × 1014 m/s2

The smelting of a metal
(a) Raises the temperature above the melting point. (b) Separates the metal from the ore. (c) Deforms the metal into a shape. (d) Cools the metal very rapidly from a high temperature.
Ice cubes submerged at the bottom of a liquid indicate that the liquid
A) produces insufficient buoyant force on the ice. B) is warmer than the ice. C) is only partly displaced by the submerged ice. D) is less dense than ice.
Why is continental crust lower in density than seafloor crust?
A) Continental crust is made of rock, while seafloor crust has more metals. B) Continental crust is made from volcanic rock called basalt, which is lower in density than what the seafloor crust is made from. C) Continental crust is made from remelted seafloor crust and therefore only the lower-density material rises to form it. D) Continental crust is actually denser than seafloor crust. E) Seafloor crust is more compact due to the weight of the oceans, but it is made of the same material as the continental crust.
A proton and a deuteron are moving with equal velocities perpendicular to a uniform magnetic field. A deuteron has the same charge as the proton but has twice its mass. The ratio of the acceleration of the deuteron to that of the proton is:
a. 1. b. 2. c. 0.5. d. There is no acceleration in this case.
