Two people play tug of war. the 100-kg person on the left pulls with 1,100 n, and the 75-kg person on the right pulls with 870 n. assume that neither person releases their grip on the rope with either hand at any time, assume that the rope is always taut, and assume that the rope does not stretch. what is the magnitude of the tension in the rope in newtons

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

What are similarities and differences between refraction, reflection, diffraction and absorption?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
