Part b The smaller (16, \Omega,16Ω) resistor is replaced by an 8, point, 0, \Omega,8.0Ω resistor. The 4, point, 0, V,4.0V cell remains the same. What value resistor would replace the larger (20, \Omega,20Ω) resistor if the power dissipated in the smaller resistor is to remain the same as in the previous part of the question? Give your answer to 2 significant figures.

part a A series circuit consists of a 4, point, 0, V,4.0V cell and two resistors of value 20, \Omega,20Ω and 16, \Omega,16Ω. What is the power dissipated in the 16, \Omega,16Ω resistor, to 2 significant figures?

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.
