During a storm, a tv reporter says, "the ocean
waves are 3 meters high. they are about 45 m
apart and are hitting the shore every
15 seconds." think about the four basic
properties of waves and describe these ocean
waves using the correct science words. (hint:
you will need to do some calculations first.)

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.

Why are nonmetals more likely to react with eachother by sharing electrons
