Answer:
3.91407 rad/s
11.742 rad/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement = 79 cm
g = Acceleration due to gravity = 9.81 m/s² = a
If the bread is rotating 1 side of a rotation would be 0.25 as there are 4 sides
Angular speed is given by
The minimum angular speed is 3.91407 rad/s
The maximum angular speed is 11.742 rad/s
Answer:
Explanation:
The centripetal acceleration of an object in circular motion is the acceleration with which the object is attracted towards the center of the circular orbit. Mathematically, it is given by
where
v is the speed of the object
r is the radius of the orbit
The speed of the object is also given by the ratio between the circumference of the orbit and the orbital period, T:
Substituting into the previous equation, we find a new expression for the centripetal acceleration:
In this problem:
- The radius of the orbit of the Moon is
- The period of the orbit is
Therefore, the centripetal acceleration is:
Answer:
carbon is a non metal that can conduct electricity
