Take a look at 2 organisms in the open ocean. What zone do they live in, then make a food chain with the 2 organisms. Label the organisms and use arrows to state which way the food chains go.

What will a positive and a negative charge do if they are separated from each other?

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
