If you are instead clinging to a position halfway from the center to the outer rim of the Ferris wheel, YOUR ROTATIONAL SPEED WILL STILL BE 2 REVOLUTION PER MINUTE.
This is because, every part of the wheel is moving with the same speed, so it does not matter where you sit on the wheel, the rotation per minute will still be the same. It is just like travelling inside a motor car, it does not matter whether you are sitting in the front passenger seat or at the back, the speed of the car remains the same.
Answer:
The tension increases by a factor of 8
Explanation:
We know that the tension, T in the string equals the centripetal force on the ball. So
T = mrω² = mr(2πf)² = 4mrπ²f² where m = mass of ball, r = radius of circle and f = frequency of rotation
If the radius and frequency are doubled, then r = 2r and f = 2f. So, the new tension is T' = 4mr'π²f'² = 4m(2r)π²(2f)² = 4 × 2 × 4mrπ²f² = 8T
Since T' = 8T,
So T'/T = 8.
So the tension increases by a factor of 8
Answer:
On 7.8 acres there are 31565.3 square meters
7.8 acres = 31565.3 m²
Explanation:
Conceptual analysis
Acre, square mile and square meter are area units, so their equivalences are in square units.
Known data
1 (mi)² = 640 acres
1 mi = 1609.34 m
Problem development
We know that 1 mile = 1609.34m, then: (1 mile)² = (1609.34m)²=(1609.34)²m²
We apply the known conversion factors to calculate the square meters (X) in 7.8 acres:
We eliminate acres and square miles (mi²) because they are in the numerator and denominator, so the answer is in square meters (m²)
X=31565.3 m²
On 7.8 acres there are 31565.3 square meters
7.8 acres = 31565.3 m²
Answer:
In collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.
Explanation:
In a collision two objects, there is a force exerted on both objects that causes an acceleration of both objects. These forces that act on both objects are equal in magnitude and opposite in direction.
Thus, in collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.
