calculate the pressure due to the ocean, in atmospheres, at the bottom of this trench, given that its depth is 11.0 km and assuming the density of seawater is a constant 1.025 × 103 kg/m3 all the way down.

Eddy whose mass is 55kg climbs up the 1.50 meter high stairs in 2s. calculate eddy’s power rating

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

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?
