We connect an ohmic conductor of resistance R = 10 homs to the terminals of a battery G of fem. E = 9.0 V and internal resistance r = 2.0 N. A current of intensity I then flows in the circuit. a) Make a diagram and specify the direction of the current. b) Calculate I. c) A shunt connection is connected to the terminals of R, an ohmic conductor of resistance R2 = 30 N. C.1) Calculate the new value l ’of the current intensity in the circuit. 0.2) Calculate the values, I1 and I2 of the intensities of the currents flowing respectively through R1 and R₂

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?
