+ Three forces of 20N, 90N and 30N are acting respectively on the left edge the middle and the right edge of a wooden bar of 100cm. Determine the resultant force of the three forces. .

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained

Inner peace.. jk it's  a stable electron configuration

If you're looking for an even spread of clay, silt and sand, add a considerable amount of sand and some clay until the 3 even out". soil texture triangle. silty clay loam soil is approximately 20 percent or less sand, 25 to 40 percent clay, and 40 to 70 percent silt.

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
