Consider an omnidirectional robot with a ring of eight sonar sensors that are fired sequentially. your robot is capable of accelerating and decelerating at 50 cm/s2. it is moving in a world filled with sonar-detectable fixed obstacles. the maximum range of the sonar sensors is 5 m. given the bandwidth of your sonar sensors, compute your robot's maximum speed ensuring no collisions.

According to social exchange theory, altruistic behaviors benefit the individual who performs them. t/f

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.

Emagnitude of the electrical force acting between a +2.4 ×  10–8  c charge and a +1.8 ×  10–6  c charge that are separated by 0.008 m is    n, rounded to the tenths place.
