Two streams merge to form a river. One stream has a width of 8.5 m, depth of 3.8 m, and current speed of 2.3 m/s. The other stream is 6.7 m wide and 3.6 m deep, and flows at 2.4 m/s. If the river has width 10.7 m and speed 2.8 m/s, what is its depth?

Awind turbine is initially spinning at a constant angular speed. as the wind's strength gradually increases, the turbine experiences a constant angular acceleration 0.173 rad/s2. after making 2870 revolutions, its angular speed is 132 rad/s. (a) what is the initial angular velocity of the turbine? (b) how much time elapses while the turbine is speeding up?

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes
