The information we have about the channel on Mars has mostly come from satellite images and scientific models. However, rovers and landers developed by NASA have made it possible to collect information directly from the surface of Mars. Think about the channel on Mars. What information would you want to collect from the surface of Mars to help you determine whether the channel was formed by flowing lava or flowing water?

The particles that are found in the nucleus of an atom are

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?

)consider two positively charged particles, one of charge q0 (particle 0) fixed at the origin, and another of charge q1 (particle 1) fixed on the y-axis at (0,d1,0). what is the net force f⃗ on particle 0 due to particle 1?
