Derive an expression for small ow rates over a spillway, in the form of function using dimensionless quantities. Use dimensional analysis with following parameters : height of spillway P, head on the spillway H, viscosity of liquid , density of liquid , surface tension , and acceleration due to gravity g.

what are the statements? x

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

i'm on my way to history not a mistory.
