Kinetic energy (k) has dimension kg m2/s2. it can be written in terms of the momentum (p) and mass (m) as k = p^2 / 2m. determine the proper units for momentum using dimensional analysis.

Iflow from a warmer object to a cooler object until both objects are the same temperature what am i?

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
