Outside this square, he can walk at a speed 1 m/s. A fighter plane is flying horizontally at an altitude of 1.5 km with speed 720 km/h. (d) Equal path lengths are traversed in equal intervals. The time to cross this 80-meter wide river can be determined by rearranging and substituting into the average speed equation. Boy diving into the river from the wooden narrow pier. [11] [13] The body is bulky with a thin rostrum and proportionally long flippers, each around one-third of its body length. Answer A swimmer swims in still water at a speed of 5 km/hr. It hits the ground a few seconds later. (a) (A * B) * C is not zero unless B,C are parallel, (b) (A * B).C is not zero unless B,C are parallel, (c) If A,B,C define a plane, (A * B) *C is in that plane. 14:04mins. It aims to reach point A, however, because of the river speed it reaches another point B. In what direction does rain fall as observed by a ground based observer? (a) At point B, it will gain the same speed u and after that speed increases and will be maximum just before reaching C. (b) During upward journey from OtoA speed decreases and smallest speed attained by it is at the highest point, i.e., at point A. Even in safe areas, moving water can always present riskssuch as when a swimmer attempts to stand up on a rocky riverbed in strong current, risking foot entrapment. The sides of the square are 100 m. A central square of 50m * 50m is filled with sand. Niraj Kumar. 210K watch mins. So resultant velocity will be the vector sum of these two velocities. Multiple Choice Questions Single Correct Answer Type Sol: (b) . A river is flowing from east to west at a speed of 5 m/min.
