In the first second the car covers a distance of 2.0 meters. How fast will the car be moving at the end of the second second? O a) 16 m/s O b) 32 m/s O c) 2.0 m/s O d) 8.0 m/s O e) 4.0 m/sQuestion 6 (Mandatory) (1 point) Saved Which one of the following circuits has the largest resistance? a) 10 A 10 V O b) 40 A SV O d 10 A 2V O d) 20 V O e) 75 A 15 VTwo bicyclists travel at a uniform speed of 15 km/h toward each other. At the moment when they are 30 km apart, a bumble bee flies from the front wheel of one of the bikes at a uniform speed of 25 km/h directly to the wheel of the other bike. It touches it and turns around in a negligibly short time and returns at the same speed to the first bike, whereupon it touches the wheel and instantaneously turns around and repeats the back-and-forth trip over and over again - successive trips becoming shorter and shorter until the bikes collide and squash the unfortunate bee between the front wheels. What was the total mileage of the bee in its many back-and-forth trips from the time the bikes were 30 km apart until its hapless end? (This can be very simple or very difficult, depending on your approach.) Why? O a) This problem can not be solved O b) 50 km O c) 20 km O d) 25 km e) More than 50 kmQuestion 10 (1 point) How much energy is dissipated in braking a 1000-kg car to a stop from an initial speed of 20 m/s? a) 135 000 1 O b) 120 000 ] O c) 270 000 J O d) 120 000 J e) 165 000 JQuestion 19 (1 point) V Saved The total resistance of a 6-ohm resistor and a second 6-ohm resistor in parallel is O a) 37 ohms. b) 12 ohms. O c) 20 ohms. O d) 6 ohms. O e) 3 ohms.The coefficient of static and kinetic frictions between a 6.0 kg box and a desk are 0.10 and 0.15, respectively. What is the net force on the box when a 10 N horizontal force is applied to the box? ( a) 2.2 N b) 8.8 N O c) 5.9 N O d) zero
