A velocity selector 1ms a magnetic field of magnitude 0.3 T perpendicular to an electric field of magnitude 0.32 MV/m. The mass of an electron is 9.11 times 10-31 kg. How much energy must electrons have order to pass through undeflected? Answer in units of eV
A spring-loaded gun, fired vertically, shoots a marble 6.4 m straight up in the air. What is the marble's range
A submarine is 304 m horizontally out from the shore and 126 m beneath the surface of the water. A laser beam is sent from the sub so that it strikes the surface of the water at a point 232 m from the shore. If beam just strikes the top of a building..
An ocean liner leaves New York City and travels 20.0° north of east for 199km. How far east and how far north has it gone? In other words, what are the magnitudes of components of ship's displacement vector in the following directions.
An astronaut on the Mars attaches a small brass ball to a 1.00- length of string and makes a simple pendulum. She times 13 complete swings in a time of 35.4 seconds. From this measurement she calculates the acceleration due to gravity on the Mars.
