Apotential difference of 35 mv is developed across the ends of a 12.0-cm-long wire as it moves through a 0.27 t uniform magnetic field at a speed of 4.0 m/s. the magnetic field is perpendicular to the axis of the wire. part a what is the angle between the magnetic field and the wire's velocity?

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
