Aphysicist performing a sensitive measurement wants to limit the magnetic force on a moving charge in her equipment to less than 1.00 x 10 -12 n. what is the greatest the charge can be if it moves at a maximum speed of 30.0 m/s in the earth’s field? you may assume the earth’s magnetic field is 5.00 x 10 -5 t.

What is the relationship between the wavelength of a wave and it's energy?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
