Current can flow only downhill in a water conduit because of "gravity". Gravity pushes everything here on earth downwards. If a water is situated in a tank the higher tank is lifted up the more water will flow. The water can only flow uphill if there is an energy that provides to move it upward.
The force applied to raise the block would be 250N
Answer:
Volleyball was invented in 1895 by William G. Morgan, physical director of the Young Men's Christian Association (YMCA) in Holyoke, Massachusetts.
It will be 9.55 m/s.
as the velocity vector will be
6.38 in vertical direction pointing downwards after 1 second
and the horizontal will be 4.86
the angle between them is 35°
thus using parallelogram law of vector addition
you get
v^2 = 6.38*6.38+4.86*4.86+2(6.38)(4.86)cos35°
v^2 = 40.7044+23.61+26.92
v^2 = 91.24
v = 9.55 m/s
Answer:
11.04m
Explanation:
Convert kilometers to meters: 53km/h x 1000 = 53,000m/h
Convert hours to seconds: 53m/h / 3600 =14.72m/s
14.72 (.75) = 11.04
