At a certain plane in space, the particle flux density is isotropic for 0 ws1 and zero for negative w, where w is the cosine of the angle made by the particle direction and a normal to the plane of reference. in that plane, what is (a) jn (w), the angular distribution of the flow rate, and (b) jt, the flow rate for all positive w?

Which force is most responsible for binding together an atom's protons and neutrons? electrostatic gravitational nuclear magnetic

An object resting on a table weighs 100 n. with what force is the object pushing on the table? with what force is the table pushing on the object? explain how you got your answer.

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
