Answer:
See the answer below
Explanation:
Dora ran a complete lap around the track, including the straight side of the track; while Clark only ran a 100-meter along the straight side of the track.
<em>Hence, </em><em>Dora</em><em> must have traveled a greater distance.</em>
Dora finished the race where she started it, her change in position or displacement is zero. Clark finished the race at a different point from their starting position.
<em>Hence, </em><em>Clark</em><em> a greater change in position than Dora.</em>
Answer:
41.8° to the vertical ( west of North) , 44.6 s
Explanation:
Using Pythagoras theorem, taking the direction it must go line as the hypotenuse
vh² = vs² + vd² vs is the speed of the stream, vh is the speed in the direction it must go to the vertical and vd is the speed going directly north
3 ² = 2² + vd²
9 - 4 = vd²
√5 = vd
2.24 m/s = vd which is the resultant speed
the direction it will go = tan θ = 2 / 2.24
θ = tan⁻¹(2 / 2.24) = 41.8° to the vertical ( west of North)
b)t = distance / v = 100 / 2.24 = 44.6 s
Hey
in the summer it is because of the meting of snow
in the spring it is rain
hope l helped
