Answer:
Question A:17.92 m/s
Question B:0.6 seconds
Explanation:
Question A:
Initial velocity(u)=24m/s
Height(h)=13m
acceleration due to gravity(g)=9.8m/s^2
Final velocity=v
v^2=u^2-2xgxh
v^2=24^2-2x9.8x13
v^2=24x24-2x9.8x13
v^2=576-254.8
v^2=321.2
Take them square root of both sides
v=√(321.2)
v=17.92m/s
Question B:
velocity(v)=17.92m/s
Acceleration due to gravity(g)=9.8m/s^2
Initial velocity(u)=24m/s
Time=t
v=u-gxt
17.92=24-9.8xt
Collect like terms
9.8t=24-17.92
9.8t=6.08
Divide both sides by 9.8
9.8t/9.8=6.08/9.8
t=0.6 approximately
Answer: Surface currents can flow for thousands of kilometers and can reach depths of hundreds of meters. These surface currents do not depend on weather; they remain unchanged even in large storms because they depend on factors that do not change. Surface currents are created by three things: global wind patterns, the rotation of the Earth, and the shape of the ocean basins. I don't know if this is right.....
Explanation:
The hydrologic cycle is the process, powered by the sun's energy, which moves water between the oceans, the sky, and the land. We can start our examination of the hydrologic cycle with the oceans, which hold over 97% of the planet's water.
