An electric field of 1.27 kV/m and a magnetic field of 0.587 T act on a moving electron to produce no net force. If the fields are perpendicular to each other, what is the electron's speed

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

Two polarizers are oriented at 40∘ to each other and plane-polarized light is incident on them. if only 16 percent of the light gets through both of them, what was the initial polarization direction of the incident light?
