Water enters vertically and steadily at a rate of 35 L/s into the sprinkler with unequal arms and unequal discharge areas. The smaller jet has a discharge area of 3 cm2 and a normal distance of 50 cm from the axis of rotation. The larger jet has a discharge area of 5 cm2 and a normal distance of 35 cm from the axis of rotation. Disregarding any frictional effects, determine (a) the rotational speed of the sprinkler in rpm (10-point) and (b) the torque required to prevent the sprinkler from rotating (10-point).

This punnett square shows the cross between two pants. one parent has round seeds (rr). and the other parent has wrinkled seeds (rr) which best describes their offspring as shown in this cross?

What is friction? how does it affect the motion of an object?

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
