WebAt. 7:28. in the video, he writes down Newton's 2nd Law in the x-direction, which is the direction that is toward the center since the circle is horizontal. So we see that the centripetal force in this case is the horizontal component of the tension, Tx = Tsin (30). That is the only force in the horizontal plane, so that is equal to the mass ... WebAug 30, 2024 · Since, distance travelled by a circular wheel = 176 m Total distance covered by the wheel = No. of revolutions made by wheel × (Distance covered in one revolution) ∴ No. of revolutions made by wheel = 176/4.4 = 40 Hence, the required number of revolutions made by a circular wheel is 40. ← Prev Question Next Question → Find MCQs & Mock Test
WebThe number of revolutions made by a circular wheel of radius 0.25 m in rolling a distance of 11 km is 7000. Explanation: Here, Number of revolutions = `"Total distance"/("Distance covered in" 1 "revolution")` Given, Radius = 0.25 m. Total Distance = 11 km = 11,000 m. Therefore, Distance covered in one revolution = Circumference of wheel = 2πr
